Overview

Located on a peninsula on the northeast corner of New Castle Island, Fort Constitution State Historic Site overlooks both the Piscataqua River and the Atlantic Ocean. In 1791, the State of New Hampshire gave the United States the neck of land on which Fort William and Mary and a lighthouse were situated. The fort was repaired, renamed Fort Constitution, and garrisoned with a company of United States artillery. Renovations, which included a wall twice as high as that of the colonial fort and new brick buildings, were completed in 1808. It is the ruins of this fort that are seen today.

Outside the old fort in the area now occupied by the Coast Guard, a completely new system of fortifications was built between 1897 and 1903. This included a battery of two eight-inch guns on disappearing carriages, a mines casement, cable tank and a storage house for mines. The harbor was protected by mines during the Spanish American War and during World Wars I and II. Fort Constitution was returned to the state in 1961 and placed on the National Register of Historic Places on July 2, 1973.
