The Custom House Maritime Museum/New London Maritime Society's mission is to preserve New London's U.S. Custom House and New London Harbor Light, and to promote and interpret the maritime history of the port of New London and the surrounding region through museum exhibitions and educational programs.
Special exhibitions include 'The Lighthouses of Eastern Long Island Sound' and Amistad: A True Story of Freedom' -' New London is the only US port to which the Amistad ever sailed.
Participation in Museum Day is open to any tax-exempt or governmental museum or cultural venue on a voluntary basis. Smithsonian magazine encourages museum visitation, but is not responsible for and does not endorse the content of the participating museums and cultural venues, and does not subsidize museums that participate.
