The Owlery was situated at the top of the West Tower at Hogwarts. This circular room was often full of hundreds of owls, both belonging to the school and pupils, who would live there during term time. It wasn’t the most pleasant of spaces. Not only was it cold and draughty (due to the windows having no glass in them), but the floor was also covered in droppings and regurgitated mouse and vole skeletons.
