The Great Hall was designed by Walter Cope (of Cope and Stewardson) in 1901 and built by Stewardson and Jamieson several years later. It was inspired by the dining hall at Wadham College, Oxford and features a king post truss ceiling painted by Lockwood de Forest with geometric renaissance patterns that continue down the wall, ending with tulip-bordered corbels situated between large, arch-shaped lead-paned windows, which flood the space with light.
Free parking is available in the visitor lot off New Gulph Road, a short walk from the hall. Handicapped parking is available near the building and access is available on the left.
