Horton Point Lighthouse in Southold was commissioned by George Washington and constructed in 1857.
Since a renovation project in 1990, it has been home to a museum, maintained by the Southold Historical Society.
Learn about the history of the property with this video, which was made possible by Heidtmann & Sons, Inc. Builders.
Our monthly series continues in October with a trip to the Suffolk County Historical Society building in Riverhead.
