It contains tables identical to those in the Great Hall; food must simply placed on the tables in the kitchens, and it magically appears in the Great Hall.

Also contained in the Entrance Hall are the four hourglasses which show current state of House Points.

The common room has a fireplace and armchairs. There are separate dormitories for girls and boys, which are subdivided by year. Girls are permitted to enter the boys' dormitories, but boys cannot visit the girls', because the founders of Hogwarts felt that boys were less trustworthy than girls. Harry Potter and Ronald Weasley learned this when Ron ran up the stairs leading to the girl's dormitory to get Hermione Granger, and the stairs turned into a flat slide, causing him to fall all the way down.

West Tower
The Owlery is at the top of West Tower.
