Overview:
Perched out in Long Island Sound, at the mouth of the Thames River, Ledge Light has served for over a century. Around 1900, the Lighthouse Board determined that the increased boat traffic to New London Harbor warranted a new lighthouse to supplement New London Harbor Light, upriver on Pequot Avenue. The New London Ledge Lighthouse Foundation was formed in 1989 to help care for this historic site and is a former chapter of the American Lighthouse Foundation. In 2015, the New London Maritime Society (NLMS) took ownership of the lighthouse under the National Historic Lighthouse Preservation Act.
