Fort Trumbull State Park
Fort Trumbull
A 19th-century granite coastal fort at the Thames River mouth in New London, with Cold War and Coast Guard exhibits and a waterside walkway.
Fort Trumbull lies on the west bank of the Thames River in New London. Its surviving granite pentagonal fort was built between 1839 and 1852 and, together with Fort Griswold across the river, guarded the river mouth. Inside, exhibits trace the story from the Revolutionary War and the War of 1812 to underwater sonar research during the Cold War. From the ramparts you can see the submarine base, New London Harbor and Groton across the river. The park has a fishing pier and a waterfront walkway; entry to the grounds is free, and the fort museum is open seasonally.
