Classroom 11

Classroom 11 is a classroom in the ground-floor corridor leading off of the Entrance Hall on the opposite side to the Great Hall. It was one of several classrooms which were not regularly used and, as such, had the slightly neglected feeling of a cupboard or storeroom.

As Firenze was unable to climb the ladder to the Divination Classroom, Albus Dumbledore arranged for his classes to take place in Classroom 11 when he was hired as a Divination professor in 1996. In imitation of Firenze's natural habitat, he also had it redecorated with a mossy floor, boulders and trees. Firenze was able to make the stars appear in the ceiling for the students to observe.
