Welcome to the Custom House Maritime Museum

Discover the maritime history and heritage of Newburyport, Massachusetts, the Merrimack River Valley, and of course the Custom House itself. Built in 1835 to facilitate tax collection on imported goods from a growing overseas trade in one of America’s earliest ports, the Custom House was designed by Robert Mills, architect of the Washington Monument and U.S. Treasury Building.  

See our unique collection of maritime art, model clipper ships, displays of famous shipwrecks, the history of the Coast Guard, and much more!
