The Custom House Maritime Museum is managed by the Newburyport Maritime Society, Inc. The Society was established in 1968 for the purpose of protecting, preserving, and communicating the maritime heritage of the Merrimack Valley and its role in American history. We are connecting the past to the living history of today through new relationships with local artistic, business and environmental organizations.
