An official Path Through History Site! Sagtikos Manor, is a unique jewel on Long Island’s South Shore. Its history spans more than three centuries from its original purchase from the Secatogue tribe by Stephanus Van Cortlandt in 1692 to the present. Family members who lived in the house included participants in the Revolutionary war and other prominent figures in state and local history. In 1790 George Washington spent the night at the house and recorded the stay in the diary he kept of his tour of Long Island. In the 19th and 20th centuries, the Manor was used for the most part as a summer home for the family. The last family member to live in the Manor owned the property from 1935 to 1985.
