Founded in 1912, Hamden Hall has grown to encompass three campuses: its Whitney Avenue campus, the Davis Street castle and the Skiff Street athletic complex, which features an indoor pool, indoor basketball courts and other facilities.
The Davis Street castle was built for Frederick D. Grave in 1906. In 1960, it briefly belonged to Eero Saarinen, who at the time agreed to serve as department head for the Yale School of Architecture. He remodeled the castle but never used it because he died in 1961.
