The Clock Tower Entrance is one of the three main entrances of Hogwarts Castle (the other two being the Viaduct Entrance and the main Entrance Hall). 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. There is controversy however, as to why the window was placed there, considering if one looks at the whole structure of the Clock Tower, a building is propped right where the window is. A portrait of Damara Dodderidge was hung here  and, in 1995, so was a portrait of Temeritus Shanks. The massive steel and iron pendulum of the Clock Mechanism above, swings slowly over this Entrance. The pendulum seems to have an imprint of a many armed star on it, if one looks closely at it with what appears to be runic symbols on the outer rim of the pendulum bob. 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. 
Behind the scenes
- For unknown reasons when Harry Potter and the other members of Dumbledore's Army pass through this entrance in the film adaptation of Harry Potter and the Order of the Phoenix, the pendulum is missing. In the film adaptation of Harry Potter and the Prisoner of Azkaban, said pendulum is always present.
- The set used to film this Entrance Hall and the Clock Tower Courtyard was renovated into the Main Entrance Hall and the Entrance Courtyard in front of the Great Hall for Harry Potter and the Goblet of Fire and subsequent films.
- In the video game adaptation of Harry Potter and the Order of the Phoenix, the large window at the back of the tower looks out onto the surrounding landscape even though there is another tower directly behind it. This is corrected in the following game.
- Harry Potter and the Prisoner of Azkaban (film) (First appearance)
- Harry Potter and the Goblet of Fire (film)
- Harry Potter and the Order of the Phoenix (film)
- Harry Potter and the Order of the Phoenix (video game)
- Harry Potter and the Half-Blood Prince (video game)
- LEGO Harry Potter: Years 1-4
