Portland Harbor Museum
Visitors are provided with an opportunity to learn about the role that Portland Harbor has played in shaping Southern Maine's economic, social, and historic character. The Portland Harbor Museum is located on the grounds of Fort Preble and has a scenic view over Casco Bay. The museum houses permanent exhibitions on a 19th-century wooden shipbuilding, a working lighthouse, and a 19th-century fort. The bow of the Snow Squall, the only surviving American clipper ship, is on display at this museum. PHM also features an annually changing exhibit interpreting Portland's maritime history.
