Stratford Point Light is a historic lighthouse in Stratford, Connecticut, United States, at the mouth of the Housatonic River. The second tower was one of the first prefabricated cylindrical lighthouses in the country and remains active. It sits on a 4-acre (16,000 m2) tract at the southeastern tip of Stratford Point. The first Stratford Point Lighthouse was built in 1822. In 1855 a fifth order lens was added to the 28-foot (8.5 m) wooden tower. In 1881, the tower and dwelling were razed and replaced with a 35-foot (11 m) tall, brick lined cast-iron tower and equipped with a third order Fresnel lens. The light was automated in 1970 with a modern beacon. It is an active aid to navigation and is used for Coast Guard housing. The lighthouse was listed on the National Register of Historic Places on June 29, 1990.
