History of Peirce Island

Peirce Island has a rich history, especially during early American wars. It's located just past the historic Point of Graves Burial Ground.

Fort Washington and Fort Sullivan

During the American Revolution, two important forts were built on and near Peirce Island in 1775. These were Fort Washington and Fort Sullivan. Fort Washington was located right on Peirce Island. It was built in a star shape using earthworks, which are walls made of earth.

These forts were named after important figures:

• George Washington, who became the first President of the United States.
• John Sullivan, a local war hero from New Hampshire.

Both forts were led by Captain Titus Salter during the American Revolution. They helped protect the area. The forts were used again during the War of 1812 but were no longer needed after that war ended.
