Bath is a city in Sagadahoc County, Maine, in the United States. As of the 2000 census, the city population was 9,266. It is the county seat of Sagadahoc County. Located on the Kennebec River, Bath is a port of entry with a good harbor. The city is popular with tourists, many drawn by its fine 19th-century architecture. It is home to the Bath Iron Works and Heritage Days Festival, held annually on the Fourth of July weekend.
Several industries developed in the city, including the manufacture of lumber, iron and brass, with trade in ice and coal. But Bath is renowned for shipbuilding, which began here in 1743 when Jonathan Philbrook and his sons built 2 vessels. Since then, roughly 5,000 vessels have been launched in the area, which at one time had more than 200 shipbuilding firms. Bath became the nation's fifth largest seaport by the mid-1800s, producing clipper ships which sailed to ports around the world.
The last commercial enterprise to build wooden ships in the city was the Percy & Small Shipyard, which was acquired for preservation in 1971 by the Maine Maritime Museum. But the most famous shipyard is the Bath Iron Works, founded in 1884 by Thomas W. Hyde. It has built hundreds of wooden and steel vessels, mostly warships for the U.S. Navy. During World War II, Bath Iron Works launched a new ship every 17 days. The shipyard is a major regional employer, and operates today as a division of the General Dynamics Corporation.
The city is noted for fine Federal, Greek Revival, and Italianate architecture, including the 1858 Custom House and Post Office designed by Ammi B. Young. Bath is sister city to Shariki (now Tsugaru) in Japan, where the locally-built full rigged ship Cheseborough was wrecked in 1889. Scenes from the movies Message in a Bottle (1999) and The Man Without a Face (1993) were filmed in the city.
