The Jumel Mansion located at 160th Street near Amsterdam Avenue, is the most historic house on Manhattan Island. It was built in 1763 by Roger Morris, the husband of that Mary Philipse, for whose hand George Washington is said to have been an unsuccessful suitor. It was a farm house in 1790, when Gen. Washington gave a dinner in the old house to his cabinet officers and their ladies. It is now owned by the City and contains a museum of Revolutionary relics. Open to visitors every day from 9 to 5.
