Sagtikos Manor is one of the oldest structures in the Town of Islip. The original structure, which was later expanded, was built in 1697 by New York City's first native-born mayor, Stephanus Van Cortlandt. The manor functioned for a time, during the American Revolution, as local headquarters for British forces under General Sir Henry Clinton. George Washington used it as a stopover during a 1790 tour of Long Island. It was added to the National Register of Historic Places in 1976.
