The Owlery, where the school owls and the owls belonging to students live, is located on the top of West Tower .
The Owlery was a circular stone room, rather cold and drafty, because none of the windows had glass in them. The floor was entirely covered in straw, owl droppings, and the regurgitated skeletons of mice and voles. Hundreds upon hundreds of owls of every breed imaginable were nestled here on perches that rose right up to the top of the tower, nearly all of them asleep
