A scuffed and faded plaque by the door indicates that this room was once called the Half-Moon Ballroom, likely in reference to its semi-circle shape, though these days the room is known simply as the Assembly Hall. A large stage stands in the middle of the wood-panelled room along the single straight wall, with a large, ornate portrait of each founder resting prominently, center stage. Four sets of wooden benches curve around it, one section for each house. This room is largely used for the Sorting Ceremony, and as a gathering space for Penwick's theater and debate clubs, respectively, though it is also used for its traditional purpose as a ballroom on occasion, during which the benches are often simply floated up to the ceiling for storage, acting as some of the most peculiar balloons that you've ever seen. Dance lessons are held here biannually for all interested parties third-year and above, with one session in January and one session in May.
