Greens Ledge Lighthouse is a lighthouse in Connecticut,
United States, off the southwest end of the Norwalk Islands, Long Island Sound, near Norwalk, Connecticut. It is on north side of the west end of Greens Ledge, west of Norwalk Harbor a mile south of the entrance to Five Mile River at Rowayton, and just over a mile southwest of Sheffield Lighthouse.

Since 1935, swimmers have been competing annually in the Arthur J. Ladrigan Swim Race, a one-mile race from the lighthouse to Bayley Beach in the Rowayton section of Norwalk.

History

When it was built in 1902, the "sparkplug" style lighthouse replaced the Sheffield Island Light. [ [http://www.lighthousefriends.com/light.asp?ID=785] "Greens Ledge Lighthouse, CT" Web page at Web site of LighthouseFriends.com, accessed September 12, 2006] At first it had a fifth order Fresnel lens. Three months after it was first lit, it was upgraded to a fourth order Fresnel lens. The 62-foot tower developed a tilt over time and the keepers also complained the station’s generators would cause the furniture to move to one side of the tower. They solved the problem by keeping all the furniture on one side. The light was automated by the United States Coast Guard in 1972 and in 1990 it was added to the National Register of Historic Places. The light is an active aid to navigation is not open to the public.
