Hogwarts Castle is a large, seven-story high building supported by magic, with a hundred and forty two staircases throughout its many towers and turrets and very deep dungeons. The castle was built in the late Early Middle Ages (c. 993) by a wizard architect and the four most celebrated wizards of the age: Godric Gryffindor, Helga Hufflepuff, Rowena Ravenclaw and Salazar Slytherin. The Castle houses Hogwarts School of Witchcraft and Wizardry, regarded as the finest wizarding school in the world.
Hogwarts is built in a valley area — surrounding mountains are part of the landscape — with the fairly large Great Lake to the south of the main building. The huge main oak front doors leading into the Entrance Hall face the west, and open up to sloping lawns. The deep Forbidden Forest extends around to the west of the Castle. There are also exterior greenhouses and vegetable patches on the school grounds.
It was the setting of the final battle of the Second Wizarding War, the Battle of Hogwarts, which resulted in the deaths of several witches and wizards who fought in defense of the castle, including Remus Lupin, Nymphadora Tonks, Fred Weasley, Colin Creevey, Lavender Brown, and Severus Snape. The castle was slightly damaged, but ultimately the Order of the Phoenix won when Harry Potter defeated his nemesis, Lord Voldemort, in the Great Hall.
The castle is supported by magic (unable to be maintained or constructed by any other means), a good example being the moving staircases, a feature contributed by one of the four Hogwarts founders, Rowena Ravenclaw.
Hogwarts is also protected by numerous ancient spells and incantations, such as the Anti-Disapparition Jinx; this can, however, be overridden by the Headmaster (and Dumbledore's phoenix, Fawkes) when necessary. It is also unplottable and has been bewitched so that, if Muggles approach the castle, all they will see is a mouldering ruin with a sign warning them to keep out and that it is unsafe. The protective magic over Hogwarts is not only strong enough to apparently resist the dispelling effects of the Taboo but also to repel even talented dark wizards.
As a result of all the magic that occurs on premises (both from learning students, magical artefacts therein and the enchantments cast over the building itself) a magical atmosphere pervades the entire structure, causing any technology that is not adapted to run off of itto fail. This is presumably why candles and lanterns are still in use. Mechanical things like watches seem to do alright, as Colin Creevey's (traditional, Muggle) camera seems to have worked until it was destroyed by the Basilisk's eyes. (Colin mentions that another student told him that he could develop the pictures so that they moved. One of his pictures shows Harry trying to escape a picture of him and Gilderoy Lockhart.)
Below The Ground Floor
Chamber of Secrets
- "He was standing at the end of a long, dimly lit chamber. Towering stone pillars entwined with more serpents, rose to a ceiling lost in darkness, casting long, black shadows through the odd, greenish gloom that filled the place."
- —Harry, exploring the Chamber.[src]
The Chamber of Secrets was allegedly created deep under the dungeons of Hogwarts Castle during the Medieval times by Salazar Slytherin, who disagreed with the other Hogwarts Founders on the merits of blood purity. The Chamber of Secrets was home to an ancient Basilisk, which was intended to be used to purge the school of Muggle - born students. The entrance can be found in Moaning Myrtle's bathroom on the second floor. In order to gain entrance one must say "open" in Parseltongue and a sink will open into a slide. While falling down the large, dark pipe, one can see hundreds of other pipes leading off. At the end of the pipe, one is launched into a damp, stone chamber. This room is stated to be "miles beneath the school" and under the Lake. This is where Tom Marvolo Riddle used his ability to speak parseltongue and attack Harry Potter.
The dungeons of Hogwarts Castle are located under the school, and it is colder there than in the main castle.
This cupboard is a small room off the Dungeon Corridor, just before the dungeon hall. This room was where Rubeus Hagrid hid Aragog in the early 1940s and, consequently, where Hagrid was framed by Tom Riddle on 13 June, 1943 as the one who had unleashed Slytherin's monster.
Deathday Party Hall
This was one of the roomier dungeons at Hogwarts Castle. The room is accessible via the Dungeon Staircase. On 31 October, 1992, this dungeon was where Sir Nicholas de Mimsy-Porpington's five-hundredth Deathday Party was held.
The Potions Classroom is where Potions classes are taught. The classroom used to be squared-sized, very large, with large tables and windows. From 1995-1996, the classroom was an oval shape and relatively smaller, with small work tables. In 1996, the classroom was extended, adding space for more work tables.
There is a storage basement under the Potions classroom at Hogwarts Castle. It is accessible via a trapdoor and it is used to store cauldrons, ingredients and phials.
Head of Slytherin's Office
This office was used by Severus Snape during his long tenure as Potions master at Hogwarts. It was a gloomy and dimly-lit room found in the school Dungeons. The shadowy walls were lined with shelves of large glass jars filled with slimy, revolting things, such as bits of animals and plants, floating in potions of varying colours. The office had a fireplace. In a corner, there was a cupboard containing Snape's private stock of potion ingredients. The office is sealed with a spell only wizards can break.
Slytherin Common Room
The Slytherin Dungeon is located behind a wall in the dungeons of Hogwarts. A Password spoken to the wall is required to enter it; whereupon a passage is revealed leading to the Common room—a low-ceilinged, dungeon-like room with greenish lamps and chairs. This dungeon extends partway under the lake. Off of this room also includes the Slytherin Boys Dormitory.
Philosopher's Stone chambers
These chambers were a series of rooms underneath Hogwarts School of Witchcraft and Wizardry that served as the defences surrounding the Philosopher's Stone during the 1991–1992 school year. There were seven chambers in total that contained an obstacle or task that guarded the stone from being stolen.
- Fluffy (Stationed in the Third Floor Right Corridor guarding the trap door entrance to the chambers below)
- Devil's Snare
- Winged Keys
- Human Chess Game
- Logic riddle 
- Mirror of Erised

Hufflepuff Common Room
- "It is a very cosy and welcoming place, as dissimilar as possible from Snape’s dungeon. Lots of yellow hangings, and fat armchairs, and little underground tunnels leading to the dormitories, all of which have perfectly round doors, like barrel tops"
The Hufflepuff Basement is the common room for Hufflepuff students at Hogwarts. The entrance to the Hufflepuff Basement is hidden behind a stack of barrels. It can be entered by tapping a certain rhythm on the barrels. It is located near the kitchens. The cellar is decorated with yellow hangings and filled with fat armchairs. Underground tunnels lead off to the students' dormitories and all the doors are perfectly circular, like barrel tops. This is the only common room Harry Potter does not enter at some point during his years at Hogwarts.
The Hogwarts kitchen is located directly under the Great Hall, down the same staircase that leads to the Hufflepuff Common Room. It contains tables identical to those in the Great Hall and are directly below them; food must simply be placed on the tables in the kitchens, and it magically appears in the Great Hall. The kitchens are staffed by over 100 house-elves including Dobby, Winky, and Kreacher (after Harry Potter inherited him and ordered him there in 1996). To gain access to the kitchens, one must tickle the pear on a fruit portrait, which then turns into a door knob.
The Boathouse is an underground harbour at Hogwarts where the boats are stored and docked after bringing the first years to the castle every 1 September. Up until 1995 a portrait of Percival Pratt, hung on the walls, concealing a short-cut to the Grand Staircase. After Pratt's portrait was removed, there were only three entrances to this building: the path outside the Paved Courtyard, the stairs down from the Viaduct Courtyard, and the Great Lake.
The Hogwarts Entrance Hall is located on the ground floor of Hogwarts School of Witchcraft and Wizardry, with a wide marble staircase opposite the oak doors. Double doors to the right lead into the Great Hall. The Hufflepuff common room, the kitchens, the dungeons, and the Grand Staircase can also be accessed via the Entrance Hall. There is also an annex off the hall where Professor McGonagall speaks to the first years before the Sorting ceremony at the beginning of each school year.
Chamber of Reception
The Viaduct Courtyard is located off the Entrance Hall. Most students witnessed the departure of Fred and George Weasley here in the spring of 1996. This courtyard replaced the Entrance Hall antechamber beyond 1994. Part of the Battle of Hogwarts was fought here on 2 May, 1998 and in response the courtyard sustained damage along with most other parts of the school.It can be assumed that after the battle the courtyard was repaired.
The Great Hall in Hogwarts is the main gathering area in the school. Students eat their meals, receive daily owl posts, and have certain special events. The Great Hall is a large hall that can easily hold all of the school's students, staff and guests. It has tall walls that reach up to the ceiling, which is enchanted to look like the sky above. It was the scene of Harry Potter and Lord Voldemort's final showdown, which was the Dark Lord's ultimate defeat. This was because the Elder Wand refuse to kill its true master, so Harry was not killed. Since Voldemort was now a mortal man, the curse rebounded on him, killing Tom Marvolo Riddle once and for all.
The caretaker's office is the room where Argus Filch lived in Hogwarts Castle. It is connected to the Entrance Hall, on the Ground Floor of Hogwarts Castle. It is a small, simple, windowless room with a single oil lamp in the ceiling. It smells vaguely of fried fish.
This is one of the cloisters in the inner part of Hogwarts Castle. This courtyard has grass in the open area, in which a big tree has grown over the centuries. There is one massive iron Armillary Sphere that stands in the centre of the courtyard.
This classroom is where Transfiguration class is taught. The classroom is located on the ground floor around the Middle Courtyard. The classroom itself is big, surrounded by high windows, has four rows of three desks, and still has enough room for several cages and bookshelves, two chalkboards, and a desk.
Classroom Eleven is on the ground floor of Hogwarts Castle. It was used by the Centaur Firenze, who taught the subject of Divination. Albus Dumbledore changed the room to look like the Forbidden Forest, Firenze's home.
This viaduct is constructed of stone, and extends all the way down to the lake. It is connected to the Viaduct Courtyard at one end and is connected to the left long viaduct tower and the right long viaduct tower.

- Temporary Defence Against the Dark Arts Classroom
The Grand Staircase is a massive structure in Hogwarts Castle, mainly used to access each floor of the castle, including the dungeons. There are hundreds of Portraits covering the walls in this tower, some of which conceal secret passages to other areas within the school. The multiple staircases in the Grand Staircase lead from platform to platform and go as high as the seventh floor where they come to an end.
Defence Against the Dark Arts Classroom
This classroom is where Defence Against the Dark Arts class is taught. An iron chandelier hung from the ceiling, as well as a Dragon's skeleton. On one end of the classroom stands a projector that is activated by magic. Several desks and tables can be found in the classroom as well as some sets of large windows. The classroom decoration had several changes over the years, spanning from lots of pictures of Gilderoy Lockhart to tons of skeletons and Shrunken Heads.
History of Magic Classroom
This classroom is where History of Magic classes are taught at Hogwarts School of Witchcraft and Wizardry. The subject is taught by Professor Cuthbert Binns, a ghost, who is widely regarded by almost all Hogwarts students as the most monotonous and boring teacher in existence.
Muggle Studies Classroom
The Hospital wing was run by Poppy Pomfrey. Students who suffer mishaps during the school year are sent or brought to the hospital wing for treatment. The hospital wing is well equipped to deal with all manner of magical and mundane injuries, from broken limbs to regrowing lost bones. Only in the most severe cases
are students sent to St. Mungo's Hospital for Magical Maladies and Injuries for further treatment, such as when Katie Bell touched a cursed Opal necklace in 1996.
This office is a large room adjacent to the Hospital wing at Hogwarts Castle owned by Poppy Pomfrey, the matron. It contains a bookcase, a desk, two closets, two beds for patients, and another bed closed off from the room by a curtain.
Gryffindor Head's Office
The Gryffindor Head Office is positioned on a corridor which may be accessed by climbing the large staircase in Hogwarts' Entrance Hall. This office was occupied by Professor McGonagall, head of Gryffindor house, for many years.
This corridor located on the first floor of Hogwarts Castle. It connects the Viaduct Entrance to the main first floor. Its walls are covered in tapestries and, hung over the tapestries, portraits of wizards.
This storeroom is located in the Tapestry Corridor, this was where Severus Snape stored his private supply of potions and potion ingredients. It was one of two known potions' store rooms in the castle; this being his private store; the other being the student store cupboard. The students cupboard is located in the dungeons. Items stored in Snape's store room included Veritaserum and ingredients for Polyjuice Potion.
Girl's Lavatory - Out of Order (Moaning Myrtle's Bathroom)
The Quad battlements
There were battlements all around the top of The Quad at Hogwarts Castle.
These battlements were used by the Hogwarts defence during the Battle of Hogwarts. They were heavily damaged during the course of the battle, with parts of the floor falling in, revealing the corridors below.

Defence Against the Dark Arts Professor's Office
The office used by the Defence Against the Dark Arts Professor at Hogwarts School of Witchcraft and Wizardry is located on the second floor of Hogwarts Castle. It is connected to the Defence Against the Dark Arts classroom by two staircases.
The Armoury is a corridor adjacent to the Trophy Room. There are a bunch of suits of armour on exhibition in this corridor.
This classroom is where Charms classes are taught at Hogwarts School of Witchcraft and Wizardry. The classroom has four long, large desks that are built like stairs, and are located on both sides of the classroom. There is also a large fireplace in the room, as well as several stacks of books, where Professor Flitwick lectured his pupils.
Clock Tower Entrance
This is one of the three main entrances of Hogwarts Castle. It consists of a large open space at the base of the Clock Tower with two stairwells going up towards the upper levels of the tower. Opposite the main entry there is a large window. A portrait of Damara Dodderidge was hung here and, in 1995, so was a portrait of Termeritus Shanks. The massive pendulum of the Clock swings over this entrance. The entrance can be sealed with a portcullis (which can be lowered and raised with the aid of a lever) and the massive double doors can be locked with numerous bolts.
The Library is located on the third and fourth floors of Hogwarts School of Witchcraft and Wizardry and contains tens of thousands of books on thousands of shelves. Overseen by Madam Irma Pince, the library is where students can go to peruse or borrow books to supplement their studies (or for personal enjoyment). The library closes at 8 pm.
One-Eyed Witch Passage
The One-Eyed Witch Passage is a secret tunnel that leads from Hogwarts to the cellar of Honeydukes Sweetshop in Hogsmeade. Harry Potter first learned of it from Fred and George Weasley when they gave him the Marauder's Map in 1993.
The Trophy Room is where awards, trophies, cups, plates, shields, statues, and medals are kept in crystal glass displays. This room also contains a list of Head Boys and Head Girls. Prominently displayed are Hogwarts Awards for Services to the School, with known recipients being Tom Marvolo Riddle, Harry Potter and Ron Weasley. Probably, in 1995, the Triwizard Cup was placed here as well. The Trophy Room is connected to an Armour Gallery.
Third Floor Corridor
The Third Floor Corridor on the right side of the Castle was out of bounds during the 1991–1992 school year because it was the access point to the Chambers where the Philosopher's Stone was being hidden. Fluffy, a three-headed dog owned by Rubeus Hagrid, guarded a trap door that led into the Chambers.
Other locations on the third floor
The Restricted Section is an area in fourth floor section of the Hogwarts Library closed off by a rope and only accessible to students with permission from a professor. In order to enter, they must present a signed note from a professor. The books within the Restricted Section typically discuss the Dark Arts or other information not for the general public or young children. They may be studied by older students for Defence Against the Dark Arts.
This study area is a library on the fourth floor of Hogwarts Castle, located near Classroom 4F. There is a secret passageway hidden behind a bookshelf which leads to the Seventh Floor Corridor, just opposite a portrait of Sir Cadogan, as well as another behind a tapestry, which Hermione Granger accessed using Draconifors. There is a large fireplace, and a door leading to the Fourth Floor Corridor.
This room is where the Mirror of Erised was kept from September to December 1991 and where Harry saw the image of himself and his deceased relatives including his parents. After this it was moved under orders from Dumbledore to protect the Philosopher's Stone.
Cuthbert Binns's office
This office was used by Cuthbert Binns as Professor of History of Magic at Hogwarts School of Witchcraft and Wizardry. The office had a fireplace. It also had two closets, the teacher's desk and a table. Behind a curtain was Cuthbert's bed, although since becoming a ghost it is unlikely that he used it.
Other locations on the fourth floor
This is a special bathroom that is restricted to use by school Prefects, Head Boys, Head Girls and Quidditch captains. It is located on the fifth floor behind the fourth door to the left of a statue of Boris the Bewildered, which only opens when given the correct password, which when mentioned in the fourth book; by Cedric Diggory, is 'Pine Fresh.'
Other locations on the fifth floor
- Boys' Restroom
- Classroom 5B
- Fifth Floor Corridor
- Fifth Floor hospital tower corridor

- Wizard Card Collectors' Club room
Sixth Floor Corridor
The Sixth Floor Corridor is one of the many corridors in Hogwarts Castle. It includes a professor's office and some kind of birds that Draco Malfoy used in his plan to mend the Vanishing Cabinet in the Room of Requirement. It is very similar to the Seventh Floor Corridor.
This is a large hall located on the sixth floor of Hogwarts Castle. There is a huge fireplace in the center of the room and some portraits hung on the walls. There are various suits of armour, which guard the room after the sun is down. The entrance is located on the Glanmore Peakes' Corridor and it has an entryway to the room Fred and George Weasley hid the Marauder's Map.
There is a passage leading from this bathroom to the seventh floor.
Study of Ancient Runes Classroom
This classroom is where Study of Ancient Runes and Ancient Studies classes are taught at Hogwarts School of Witchcraft and Wizardry. It includes some desks, a bookcase and a lectern for the professor.
Horace Slughorn's office
This office was once used by then-Defence Against the Dark Arts Professor Galatea Merrythought, it is now used by Horace Slughorn, Potions Master. Fairly roomy, this office included a fireplace with two large sofas surrounding it, a round dinner table big enough to sit ten people and access to a private balcony. It had enough space to hold a Christmas party. Also, the room has two entrance doors, with at least one connecting to the sixth floor.
Room of Rewards
This room is a secret room at Hogwarts that notes students' various achievements. It can be accessed via the portrait of Vindictus Viridian on the Grand Staircase. It is not to be confused with the Trophy Room.
Other locations on the sixth floor
- Classroom 6A
- Empty classroom on the sixth floor
- Glanmore Peakes' Corridor
- Writing Supplies Room
- West Tower battlements
Ravenclaw Head's Office
The Ravenclaw Head's office is the thirteenth window from the right of the West Tower. The office contains portraits, a desk, and sleeping quarters. This was where Sirius Black was held captive, awaiting the Dementor's Kiss in 1993. He was rescued by Harry Potter and Hermione Granger, and escaped on Buckbeak the Hippogriff.
Room of Requirement
The Room of Requirement is a secret room in Hogwarts that only appears when a person is in great need of it. The room then transforms itself into whatever the witch or wizard needs it to be at that moment. It is believed that the room is Unplottable, as it does not appear on the Marauder's Map, nor do its occupants, although this could simply be because James Potter, Remus Lupin, Sirius Black, and Peter Pettigrew never found the room.
Hall of Hexes
The Arithmancy Classroom is where Arithmancy classes are taught at Hogwarts School of Witchcraft and Wizardry. It is located on the seventh floor of Hogwarts Castle. It includes number charts, a blackboard and large rows of tables for students to sit in. It may also be where Advanced Arithmancy Studies is taught.
Fat Lady's Corridor
This corridor contains the portrait of the Fat Lady that serves as the entrance to Gryffindor Tower. The corridor is at least one turn away from the Grand Staircase. In the 1993-1994 school year, security trolls were stationed here to protect the Fat Lady following the attack on her by Sirius Black.
This wing has hundreds of bookshelves lined along the walls and various tables and furniture placed around the room. It serves the Castle as a reading room and study hall. There are two entrances; one in the seventh floor corridor and the other by the Fat Lady's portrait.
This bathroom is accessible through a portrait in the reading room, as well as a door on the other side of the castle. It was unused prior to 1991, by which time Fred and George Weasley had taken up residence there and set up their own shop for Gryffindor students. In 1993, the twins abandoned the bathroom and set up their shop in a different bathroom on the sixth floor in the Glanmore Peakes' Corridor.
This is where Divination classes are taught at Hogwarts. It is located in the North Tower. It is accessible through a circular trapdoor and is described as looking like a cross between somebody's attic and an old-fashioned teashop. The Divination Staircase leads to this classroom.
Divination Professor's office
Other locations on the seventh floor
The Astronomy Tower is the tallest tower at Hogwarts Castle surrounded by a parapet and turret. It is where students study the stars and planets through their telescopes in Astronomy lessons with Professor Aurora Sinistra. This is usually done at midnight where the stars are best seen. The tower is usually out-of-bounds except for classes. All the way down from the boathouse you can see the huge window of the Astronomy Tower. Located within this tower is the Astronomy Corridor, Astronomy reading room, Astronomy classroom, Astronomy stairwell, Astronomy department and the Astronomy Room. In 1997, Hogwarts' headmaster, Albus Dumbledore was killed here on this tower by his eventual successor, Severus Snape. However, it was planned between Dumbledore and Snape to spare Draco Malfoy being a murderer and spare the headmaster from a slow painful death. This was because Dumbledore's hand was poisoned by a dangerous curse created by Tom Marvolo Riddle, to protect his Horcrux (Marvolo Gaunt's ring).
The Bell Towers are two towers that rise over the main entrance to the Herbology Greenhouses. Between the two towers are a set of double wooden doors which lead along the Ground Floor Corridor. Inside the left Bell Tower is Filch's Office.
The Clock Tower does not begin at the Ground Floor level. Because it is placed on top of a hill, the Tower begins at the Third Floor level. When you enter the Tower, there is a huge space, like an Entrance Hall with flights of wooden stairs at the right and left side. The first landing is at the Fourth Floor level. It is at this landing that are the clock's gears and face. This same corridor connects the Tower to the remaining castle. If you go up another flight of wooden stairs, you will get to another landing, this time at the Fifth Floor level. It is in this landing that are the clock's bells; some massive gold and copper bells. There is another corridor at this landing; like the other, it links the Tower to the main castle.
The Dark Tower is a small but high tower near the Transfiguration Courtyard at Hogwarts Castle. This tower seems to be used as a prison. It has several prison cells, with the topmost being at the roof. The cells are not, however, charmed or otherwise protected against breaking-in from the outside. It has seven floors.
Defence Against the Dark Arts Tower
The Defence Against the Dark Arts Tower overlooks the Suspension Bridge. The tower has a "semi-circular" shape and is where DADA lessons are held and where the DADA professor's office is. Minerva McGonagall's office is located on the first floor of this tower. The Defence Against the Dark Arts staircase runs through the centre of this tower.
Grand Staircase Tower
This tower is probably the most prominent and recognisable feature of Hogwarts Castle. The tower is a circular shape and has a cone shaped roof. The Grand Staircase is located here, and at the top of this tower, are three smaller towers which make up the Headmaster's tower and serve as the Headmaster's office and residence.
Gryffindor Tower is located behind the portrait of the Fat Lady on the Seventh Floor of Hogwarts Castle. A Password is required to enter it, which is spoken to the portrait. A circular hole is behind the painting, leading to the Common room, which is a circular room where Gryffindor students can relax after a long day of studying. The Common room is full of squashy armchairs, tables, and a bulletin board where school notices, ads, lost posters, etc. can be posted. A window looks out onto the grounds of the school, and a large fireplace dominates one wall.
The Gryffindor dormitories are also located in the Tower, with two doors leading off from the Common room that open to spiral staircases. One of them leads to the girls dormitory, the other to the boys. The stairs to the girls dormitories are enchanted to become a slide if any boy attempts to climb them, but not vice-versa, since it was deemed that girls were more trustworthy than boys.
The Headmaster's office is located within this tower. To gain entrance, a password must be given to a stone gargoyle, which will move aside at the correct password to reveal a spiral staircase with moving steps. The office is a circular room with windows, decorated with portraits of previous Headmasters including Dilys Derwent and Phineas Nigellus Black. Many magical instruments are kept here, such as the Sorting Hat and the Pensieve.
The Hospital Tower has a semi-ovular shape. It is located on one side of The Quad and is at the end of the hospital corridor which connects the Clock Tower to the rest of the castle. On the first floor of the tower is the hospital wing and school matron's office. There is also a staircase that leads to the fourth-floor corridor and, by extension, to the Grand Staircase.
The North Tower is one of the many towers in the castle. The tower is the location for Divination classes and the Divination teacher's office. The entrance consists of a ladder leading through a trap door.
The Ravenclaw Tower is located on the west side of Hogwarts, the staircase leading up to the common room is presumably located on the fifth floor, and is the location of the Ravenclaw common room and dormitories. The entrance to the room is at the top of a spiral staircase, and is a door without doorknob or keyhole but a bronze knocker in the shape of an eagle. In order to enter the room, you must answer a question asked by the eagle knocker; if you answer wrong, you must wait for someone who gets it right.

The Forbidden Forest
Also known as Dark Forest or Black Forest, the forest borders the edges of the Hogwarts School of Witchcraft and Wizardry grounds. As its name suggests, it is strictly off limits to students - except in the case of detention, or Care of Magical Creatures lessons that occasionally take place there. Of course, with the various dangerous creatures, such as centaurs, Thestrals, unicorns, Hippogriffs and Acromantula living in the Forest, few students would probably even want to venture into it.
Greenhouses and Gardens
There are at least three greenhouses in which Herbology classes are held, under Professor Sprout's supervision. Greenhouse Three is restricted to students as it houses dangerous plants such as Venomous Tentaculas, Mandrakes, and others.
The Great Lake is a large body of water located to the south of the castle. It is about half a mile in diameter and the Hogwarts plumbing network drains into it. It is home to a giant squid and a colony of Merpeople. The lake was also used as the site of the Second Task of the Triwizard Tournament.
The school has its own Quidditch pitch where each house's Quidditch teams practice and play games against each other. Each year will see a total of six inter-house matches, along with numerous training sessions by each house team.
The Quidditch Gate is the entrance to the Quidditch Pitch. It is flanked by two stone structures which resemble two of the spectator towers surrounding the pitch. Inside the gate, several trophies and shields are housed. Through the gates leads to a steep winding downhill decent from the vicinity of the Wooden Bridge.
The Entrance Gates to Hogwarts are located a short distance from Hogsmeade Station. The gates would be opened on the first day of term and carriages pulled by Thestrals would take students up to the castle. The Entrance Gates are made of magnificent wrought iron and are flanked by two columns topped with statues of winged boars. Just a few yards from the gates is a small guardhouse with a tall chimney.
Clock Tower Courtyard
The Clock Tower Courtyard is a cloister on the base of the Clock Tower at Hogwarts School of Witchcraft and Wizardry. This cloister seems to be one of the older parts of the castle and the ceiling and walls are dilapidated. It also leads to the Wooden Bridge.
The Wooden Bridge is a feature of Hogwarts Castle. The bridge appears derelict, and is constructed of wood beams which extend to the floor of the ravine it lays across. The roof of the Wooden Bridge is sagging and appears thatched and tarred. The bridge blends in with the natural environment surrounding it.
The Wooden Bridge begins at one end of the Clock Tower Courtyard, at the base of the Clock Tower. At the end of the Wooden Bridge there is a small stone gazebo with benches. Outside of it is the Sundial Garden. Given its unstable look it is possibly held up by magic.
This is where Flying classes are taught to first years at Hogwarts School of Witchcraft and Wizardry by Madam Hooch. The grounds are flat, short-cut grassy areas and are located near the Herbology greenhouses. It is overlooked by the Training Grounds Tower.
The White Tomb is the only grave at Hogwarts School of Witchcraft and Wizardry. Located on the shores of the Lake, it is the final resting place of Albus Dumbledore, who willingly gave his life in the service of the Order of the Phoenix fighting Lord Voldemort's Death Eaters in the course of the Second Wizarding War.

Book of Monster's Repair Workshop
The Book of Monster's Repair Workshop is one of the rooms at Hogwarts Castle that is seen on the Marauder's Map. It is, presumably, the place where damaged copies of The Monster Book of Monsters are repaired.
The Cauldron cupboard is one of the rooms seen on the Marauder's Map. It is possibly a store room where cauldrons are kept. It is possible that the cupboard is close to the Potions Classroom or Snape's provisions cupboard.
Stink Bomb Store
The Stink Bomb Store is one of the rooms seen on the Marauder's Map. It is possibly an illegal store, because when a Hogwarts Professor bursts in the students inside it run out of the room. It is (possibly) the place where Stink Bombs and Dungbombs are sold.
This is a wide, curved corridor in the Hogwarts Turris Magnus at Hogwarts Castle. One can access the Defence Against the Dark Arts, the Ghoul Studies and Arithmancy Classrooms through this corridor, as well as Lost Wands.

- When explaining the concept of Legilimency to Harry Potter, Snape said that many ancient spells and charms guard the Hogwarts walls and grounds, ensuring the inhabitants safety.
- It's seen that the interiors are not equal to exteriors of Hogwarts. (Ex: Curved walls inside, straight walls outside. Wide inside, narrow outside.) But this is possibly because Hogwarts is supported by magic.
- Hogwarts has different architecture in every adaptations and illustrations: Gothic the film adaptation, Medieval in the first three games and Mary GrandPre's illustration, Japonism in Kazu Kibuishi's, Flamboyant/Romanesque in Pottermore, and another different styles according to the version. But it is possibly it has its own unique architecture as Hogwarts is supported by magic, making it unique.
- It is revealed in Pottermore that Hogwarts Castle is the most haunted place in Great Britain. The castle is home to 20 or more ghosts.
- In the film adaptation of Harry Potter and the Chamber of Secrets, the entrance to Dumbledore's office is located in the Middle Courtyard, but in the video game adaptation of Harry Potter and the Half-Blood Prince, the entrance is located next to the Viaduct Courtyard. In both locations, the gargoyle must have to move quite a way to get to the tower or possibly there could be some kind of magical short-cut.
Differences between books, films, and LEGO Video Games
Throughout the Harry Potter films, Hogwarts Castle has changed significantly:
In the Philosopher's Stone film, only the parts of the castle that were needed for the film were created. This means that many areas of Hogwarts were missed. Areas of the castle included in the film were:
- The Great Hall
- The Grand Staircase Tower
- The Chamber of Reception
- The Viaduct
- The Viaduct Entrance
- The Central Tower
- The Bell Towers
- The Defence Against the Dark Arts tower
- The Training Grounds Tower
- The Transfiguration Courtyard
- The Quad
- The Training Grounds
- The Stone Bridge
- The Suspension Bridge
- The Boathouse
- Hagrid's Hut
- The Quidditch Pitch
In the Chamber of Secrets film, there are a few small changes:
- The Training Grounds Tower's design has been changed, it now looks similar to the Clock Tower, only without the clock.
- The Training Grounds have been redesigned to have a more ruined aged design.
- The Greenhouses are added to the east corner of the castle below the Bell Towers.
- The Whomping Willow is added to the Training Grounds. It is possible that it was there in Philosopher's Stone, but it was never shown.
- A new staircase to the ground similar to the Boathouse staircase is added to the left side of the Chamber of Reception. It is possible that it was there in Philosopher's Stone, but it was never shown.
- A trench is added to the Quidditch stadium.
The Prisoner of Azkaban film sees the most drastic changes to the castle in the series. But, the main shape of Hogwarts is still there. These changes probably came about because of the new director, Alfonso Cuarón. These are some of the main changes that are seen in this film:
- The Clock Tower, Clock Tower Courtyard, the Wooden Bridge, the North Tower and Sundial Garden are added to the back of the castle.
- The new stair from the Chamber of Reception is removed
- The Central Tower and Bell Towers now have taller, more gothic shapes.
- The Dark Tower is added in between the DADA Tower and Central Tower.
- Hagrid's Hut is moved down the hill at the back of the castle and a Pumpkin Patch is added.
- The Whomping Willow is moved from the Training Grounds to slightly down the hill from the Sundial Garden and off the path toward Hagrid's hut.
Inside the castle there are the following changes:
- Dumbledore's Owl Podium makes its first appearance in this film.
- The bronze statue of the Hogwarts Architect in the Entrance Hall has been removed (though it returns in the fifth film).
- The extra corridor connecting the Entrance Hall to the Grand Staircase has been removed. The Grand Staircase is now directly connected to the Entrance Hall.
- The entrance to the Gryffindor Common Room is moved to the Grand Staircase.
- The Grand Staircase is made higher, and now has 10 stories.
- The furniture in the Gryffindor Common Room has been re-arranged and there are more portraits on the wall in this film than in the others. This is due to a scene which was cut from the final film in which Sir Cadogan moves through the portraits and talks to Professor McGonagall.
In the Goblet of Fire film, there are the following changes:
- The Owlery is added on a hill behind the castle.
- A path from the Boathouse to The Quad is added.
- A new entrance to The Quad is added.
- The Quad no longer has the grass verges, and is now a paved courtyard.
- The Viaduct Courtyard replaces the Chamber of Reception, which is still wrongly seen in some scenes.
Inside the castle there are the following changes:
- In the Great Hall, the raised wooden platform on which the Staff Table sits is modified slightly. A second, higher section is added, allowing for a second table to be placed in front of the existing one. This table appears to be where the people in charge of the Triwizard Tournament sit. The table disappears following this film, but the second raised section remains.
- In the Entrance Hall, the door leading into the Chamber of Reception is replaced with two large wooden doors that connect the Entrance Hall to the Viaduct Courtyard.
- The cabinets in the Headmaster's Office receive a slight makeover. They now have glass in the doors (as opposed to grilles). Also the Pensieve Cabinet has been added.
The Order of the Phoenix film sees the least changes as nothing noticeable happens to the castle. However:
- The cones on the four smaller towers in front of the Central Tower are made taller.
- Cones are added to the turrets of the Clock Tower Courtyard.
- The Sundial Garden was removed from the entrance to the Wooden Bridge and is now seen lined up behind Rubeus Hagrid's cabin.
In the Half-Blood Prince film, there are two major changes from the earlier films:
- The Astronomy Tower is added which means that the D.A.D.A. Tower and Dark Tower are removed.
- The Training Grounds Tower is replaced by another smaller bell tower.
- The Entrance Gates are added further down the hill to the back of Hogwarts. It is possible that these were present in the previous film adaptations but were not shown.
- The Central Tower has been shortened by one story to make the new Astronomy Tower seem taller.
- Two towers instead of one are now placed on the left side of the Clock Tower Courtyard. The right side remained with one tower.
- The Quidditch Pitch was moved to the opposite side of the Wooden Bridge beyond Hagrid's Hut. It is possible this change was there before, but not seen until Half-Blood Prince.
While omitted from Harry Potter and the Deathly Hallows: Part 1 aside from a brief cameo appearance, once the film was released, it was shown that although the third film had the highest number of modifications to date, Deathly Hallows: Part 2 has arguably the highest number of changes to prominent features and locations in and around Hogwarts. The noticeable changes to the castle are as follows:
- Viaduct Courtyard: It has been enlarged. Also, an archway opposite to the Entrance Hall doors connects it to the Viaduct and the floor has been modified. A short flight of stone steps that lead up to the castle doors has also been added.
- Entrance Hall: The walls are filled with Statues of Armour. The Architect of Hogwarts statue is replaced by the First Headmaster of Hogwarts statue.
- Viaduct Entrance: The two main larger towers on either side of the entrance have been made taller.
- The Quad: The Stone Bridge Tower has been changed into a tower resembling the one on top of the Astronomy tower. A bridge has been added to the tower, connecting it to a little tower overlooking the Quad.
- Boathouse: It has a new design.
- Viaduct: It no longer connects the courtyard with the Viaduct Entrance, but now to land on the other side.
- The Grand Staircase has changed and has now taken on the appearance of a much bigger Marble Staircase, as in the books, there are fewer portraits, and the stairs do not move.
- The Wooden Bridge was made longer.
- The central tower design has a little modification.
- The Great Hall is higher and a Hogwarts crest is added to the center of the back window, although it was broken at the end of Half Blood Prince, so it could have been replaced.
- The structure connecting the Entrance Hall to the Grand Staircase Tower has been shortened by 1 floor and has two small windows looking out onto the courtyard as opposed to one large one.
It should be noted that the castle shown burning in the teaser poster is actually the look of Hogwarts in Half-Blood Prince.
Most of these modifications were made in order to make the castle more convenient for the battle scene in the film.
Many of these edits to the castle's layout throughout the films can be explained as the effect of the school's ability to change its architecture by magic. However, certain elements, such as the Ravenclaw Tower, can be considered to have always been a part of the castle and simply never seen until the film they are introduced in, and the movement of the Viaduct and the redesign of the Grand Staircase in Deathly Hallows. The grounds around the castle seem to have change great throughout the films too, most notably in Prisoner of Azkaban and Deathly Hallows Part 2.
- The Great Hall
- The Grand Staircase Tower
- The Astronomy Tower
- The Viaduct and Viaduct Entrance
- The Viaduct Courtyard and the Stone Bridge
- Hagrid's Hut and the Whomping Willow
- Filch's office
Although it is based on the castle seen in Half-Blood Prince, most of it is missing and it differs greatly from the one seen in the films:
- The Viaduct is not connected to the Viaduct Courtyard.
- The Entrance Hall is not connected to the Grand Staircase Tower.
- The Astronomy Tower takes the place of the Central Tower.
- The Stone Bridge is only connected to the Grand Staircase Tower not the right Viaduct Enterance Tower.
- The stone bridge took the place of an archway building connecting the Grand Staircase Tower to the Stone Bridge Tower.
- Elements such as the Boathouse, the Sundial Garden, and the Wooden Bridge are missing.
- The Great Lake is also missing, but this is understandable as the lake takes up a great deal of space around the castle that was unavailable to the park. Also, it was required that the castle be easily accessible to visitors.
The castle seen during the ride is Hogwarts as seen in Half-Blood Prince, but there are some differences:
- The new Boathouse from Deathly Hallows is added.
- A skinnier version of the new tower seen in the Deathly Hallows trailers, adjacent to the Stone Bridge Tower, can be seen.
The castle seen here is the same as seen in the first film.
Hogwarts in the LEGO Harry Potter game seems to be based on the castle seen in Prisoner of Azkaban, although it is based on the first four films. Presumably this is because it includes the Entrance Hall Antechamber which only appears in the first three films; also, the Central and Bell Towers have the shape used from the third film onwards. However, the Clock Tower is not connected to the castle like in the films. Additionally, it seems that the Whomping Willow will change location from the second to third year as it does in the films. The North Tower also receives its own courtyard, the North Tower courtyard.
Hogwarts in LEGO Harry Potter: Years 5-7 seems to be based on the castle seen in Harry Potter and the Deathly Hallows: Part 2. However, there are some differences. The Astronomy Tower does not overlook the Middle Courtyard, and the Dark Tower is there instead, last seen in Harry Potter and the Order of the Phoenix (film). The Boathouse, the Training Grounds Tower and the Stone Bridge tower remain unchanged, and there are two Viaducts: one connecting the Viaduct Courtyard to the Viaduct Entrance, and the other connecting the same courtyard to the grounds, as it does in the last film adaptation. Despite that, the two checkpoint towers are not there. Finally, the Defence Against the Dark Arts tower is still there.
