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.
The room is presumably used by students to study outside of Study Hall and the Hogwarts Library, and, therefore, away from Madam Irma Pince. One night, after an Anti-Dementor lesson with Professor Lupin, Harry Potter, Ronald Weasley and Hermione Granger had to sneak past Severus Snape, who met Lupin in the Study Area to give him a goblet full of Wolfsbane Potion. They managed to using a secret passageway.
