The Defence Against the Dark Arts Classroom is where Defence Against the Dark Arts class is taught. It is located on the third floor. In 1991, Professor Quirinus Quirrell taught in a different classroom because the third floor was out of bounds. An iron chandelier hung from the ceiling, as well as a Dragon's skeleton. On one end of the classroom stands a projector that is activated by magic. Several desks and tables can be found in the classroom as well as some sets of large windows. The classroom decoration had several changes over the years, spanning from lots of pictures of Gilderoy Lockhart to tons of skeletons and Shrunken Heads.
