DeWint House
20 Livingston Avenue
Tappan, NY 10983
United States
The house was built using brick and indigenous stone in 1700 by Daniel DeClark, a Dutchman, who emigrated to America in 1676 and bought the land from Native Americans in 1682. The DeWint House served as temporary headquarters for George Washington while he was Commander-in-Chief during the American Revolution. Washington signed the execution warrant in the house for Major John Andre. Andre had been captured in Tarrytown after plotting with Benedict Arnold to surrender West Point to the British.
Washington headquartered again at the DeWint House from May 4–8, 1783, while negotiating the final withdrawal of British troops from New York City. At the rear of the house stand seven small grave markers, each bearing one to three initials, which came from a nearby property. It is believed these markers came from a burial ground for slaves on that property. A 19th-century carriage house contains artifacts related to Washington, Andre, and Arnold.
