Southwest Ledge Light is an active lighthouse marking the main entrance channel to the harbor of New Haven, Connecticut. Completed in 1877, 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.[6]: 3 The lighthouse was listed on the National Register of Historic Places in 1990 as Southwest Ledge Lighthouse.[5][6]
