In the decades following Richard T. Crane, Jr.’s purchase of the property in 1910, Castle Hill came to exemplify the American Country Place Era with its farm and estate buildings, designed grounds and gardens, and diverse natural areas. The Cranes hired some of the century’s most notable architects and landscape architects. The first house built atop Castle Hill, an Italian Renaissance Revival villa designed by Shepley, Rutan and Coolidge, was razed and replaced in 1928 with the 59-room Stuart-style mansion designed by architect David Adler you see today. The Great House is furnished with period antiques.
