Bath has been a shipbuilding center since 1607. The result of its prosperity can be seen in its handsome mix of Federal, Greek Revival, and Italianate homes along Front, Centre, and Washington streets. In the heart of Bath's historic district are some charming 19th-century homes, including the 1820 Federal-style home at 360 Front Street; the 1810 Greek Revival mansion at 969 Washington Street, covered with gleaming white clapboards; and the Victorian gem at 1009 Washington Street, painted a distinctive shade of raspberry. All three operate as inns. One easily overlooked site is the town's City Hall; the bell in its tower was cast by Paul Revere in 1805.
The venerable Bath Iron Works completed its first passenger ship in 1890. During World War II, BIW (as it's locally known) launched a new ship every 17 days. Not only is it still in production today, BIW is one of the state's largest employers, with about 5,600 workers, who turn out destroyers for the U.S. Navy. (It's a good idea to avoid U.S. 1 on weekdays 3:15–4:30 pm, when a major shift change takes place.) You can tour BIW through the Maine Maritime Museum.
