The Mansion at Glen Cove was designed in 1910 by renowned architect Charles Adams Platt. John Pratt, an attorney, and executive with the Rockefeller family’s Standard Oil Company, commissioned him. Pratt was one of the scores of wealthy Americans who built grand country estates with acres of landscaped grounds at the turn of the century.
The Mansion at Glen Cove, originally The Manor, is also a movie star, used several times as a location in big Hollywood productions, and is one of the very first conference center hotels in the United States.
