Southwest Ledge Light is a lighthouse in New Haven, Connecticut. United States, on the reef at main entrance to New Haven Harbor. It was one of the first to be built on a cylindrical iron foundation, an innovation by Maj. George H. Elliot to address shifting ice that is regarded to be very important in lighthouse design.[4]:3
History [link]
Construction on the Southwest Ledge Lighthouse started in 1873 and was finished in 1877. The superstructure originally intended for this light was put on display at the Philadelphia Exposition of 1876; in order to more quickly finish the light, however, a duplicate superstructure was built and installed at this light. The original house remained at the exposition until its close, and was then used for the Ship John Shoal Light in Delaware Bay.[1]
The lighthouse was automated in 1973.
The lighthouse was listed on the National Register of Historic Places in 1990 as Southwest Ledge Lighthouse.[3][4]
The lighthouse is currently an active aid to navigation.
