Greens Ledge Light

Greens Ledge Light is a cast-iron lighthouse standing on an artificial pier foundation in Long Island Sound near Norwalk and Darien. The tapered tower structure sits in open water and marks this busy waterway for vessels passing through the region.

Construction of this lighthouse began in 1902 after Congress allocated funds for the project in 1899, starting with temporary lighting equipment. The structure served as a navigation aid for over a century in these busy waters.

The annual Arthur J Ladrigan Swim Race attracts participants who swim one mile from the lighthouse to Bayley Beach in Rowayton since 1935.

This offshore structure can only be reached by boat, so plan to travel by water to view it up close. Information about guided visits should be checked in advance since access depends on weather and available tours.

Rocks from the demolition of Radio City Music Hall were repurposed to reinforce the foundation in the 1930s and delivered by ship to the site. This unlikely connection links this lighthouse to a famous New York building through material reuse.
