Custom House Maritime Museum

150 Bank Street, New London, CT 06320 - United States




In everything we do, we work to support our community.
NLMS was formed by citizens who stopped an impending federal sale to keep NL's US Custom House intact & accessible.
That's still who we are.
Today we run a local maritime history museum, provide a free education program in NL Public Schools, and preserve the custom house & three lighthouses.

The Custom House is a lively maritime museum, preservation, and educational organization. Housed in the 187-year-old Robert Mills building at 150 Bank Street, today we are a nonprofit historic site—the nation’s oldest continuously operating U.S. Custom House and scene to much of the area’s maritime history. Since 2009, NLMS also has taken on stewardship of the three major beacons leading into this historic port: New London Harbor Light — established 260 years ago and still an active aid to navigation, it is the first and the tallest lighthouse built on Long Island Sound; Race Rock Light Station, off Fishers Island, New York, built by local legend Captain T.A. Scott and lit in 1878; and New London Ledge Light, first lit in New London harbor, in 1909.


The Custom House Maritime Museum tells the stories of New London's waterfront with exhibitions on local lighthouses, the Amistad incident, and the US Customs Service.
