Home to Boston Light, the oldest lighthouse site in the country.

This bedrock outcropping is one of the Brewsters, a group of the outermost islands in the park. It is an active Coast Guard navigational aid facility, so the buildings are not open to the casual visitor and there are no public rest rooms on the island. A carry-in/carry-out policy applies to all trash.

Short History
This two-acre island is best known as the home of Boston Light, the country's oldest continually used lighthouse site (1716). Originally financed by a tax of a penny-a-ton on all vessels entering and leaving the harbor, the stone lighthouse was largely destroyed by the British when they evacuated Boston at the close of the Revolutionary War, but was rebuilt in 1783. In 1859, the tower was raised 14 feet to its present height of 102 feet above sea level, enabling its light to flash 27 miles out into the Atlantic. By 1990, the Coast Guard had automated every lighthouse in the United States, with Boston Light scheduled to be last in the process. Preservation groups appealed to Congress and the Coast Guard and funding was appropriated to keep Coast Guard staff on the island, where they remain to this day, recording meteorological data in addition to maintaining the light and structures on the island.

Boston Light is a National Historic Landmark, listed in the National Register of Historic Places. For more information about the facility, please go to the National Park Service Maritime Heritage Program Inventory of Historic Light Stations.
