Connecticut River Museum
Housed in an 1878 steamboat warehouse, this museum tells the story of the Connecticut River through maritime artifacts, interactive displays, and ship models. The riverfront museum even has a full-size working reproduction of the world's first submarine, the American Turtle (named for its appearance); the original was built by David Bushnell, from nearby Westbrook, in 1775 as a "secret weapon" to win the Revolutionary War.
