Belfast, a city, port of entry, and the county-seat of Waldo county, Maine, U.S.A., on Belfast Bay (an arm of the Penobscot), and about 32 m. south-south-west of Bangor. Pop. (1890) 5294; (1910) 4618. It is served by the Belfast branch of the Maine Central railway (connecting with the main line at Burnham Junction, 33 m. distant), and by the coasting steamers (from Boston) of the Eastern Steamship Co. The city, a summer resort, lies on an undulating hillside, which rises from the water’s edge to a height of more than 150 ft., and commands extensive views of the picturesque islands, headlands, and mountains of the Maine coast. It has a public library. Among the industries of Belfast are trade with the surrounding country, the manufacture of shoes, leather boards, axes, and sashes, doors and blinds, and the building and repairing of boats. Its exports in 1908 were valued at $285,913 and its imports at $10,313. Belfast was first settled (by Scottish-Irish) in 1769, and in 1773 was incorporated as a town under its present name (from Belfast, Ireland). The town was almost completely destroyed by the British in 1779, but its rebuilding was begun in the next year. It was held by a British force for five days in September 1814. Belfast was chartered as a city in 1850.
