About Guilford

The town of Guilford is located in the southern region of Connecticut. It was settled in 1639. In 1643, the town became a part of the New Haven colony. In 1777, during the American Revolution, the town’s citizens organized the stealth attack on British provisions located at Sag Harbor. And then Guilford militia fought back the enemy’s attack in 1781, with only two town defenders killed.

Guilford is known for granite, quarried in Leetes Island, the town’s area. The granite was used to build the Statue of Liberty, the Brooklyn Bridge, and the Lighthouse at the Lighthouse Point in New Haven.
