In September 1975, a fire destroyed Dongan Hall, the center of the Todt Hill campus. The building's structure was irreparably damaged, and most of the Winter Memorial Library portrait and book collections was lost. A single remnant from Dongan Hall, a pendulum clock, was saved. The clock now hangs in Crowe Hall, which was built in 1976 on the site of the historic Dongan Hall building. Crowe Hall contains the Patrick Commons (the dining hall), the Head of School's office, and other administrative spaces. Haugen Hall, which houses the auditorium, the Stanley Library and arts classrooms, was also built in 1976.
