Fort Trumbull State Park

New London, CT

Fort Trumbull has a century-and-a-half-long legacy of service from the American Revolution to World War II to the Cold War. Along with serving as a federal military facility, the fort played a pivotal role in the country’s coastal defense system and as the original site of the U.S. Coast Guard. Visit the park for an interactive history, explore the massive granite fort and its ramparts for a view of the Thames River and Harbor, walk along the riverfront boardwalk, or fish the waters of Long Island Sound from our one-of-a-kind fishing pier. Pro tip: In the warmer months, take a ride on the Thames River Heritage Park water taxi for one of our favorite ways to discover the park!

Originally built in 1777 to protect the New London Harbor from British attack, the first masonry structure was destroyed after Benedict Arnold successfully raided the fort and the British burned New London to the ground.

Know Before You Go



The Fort and Museum

Built from 1839 - 1852, the fortification is part of the Third System of Fortifications, a group of forty-two forts constructed to defend the U.S. coastline and harbors. Unique in the "Third System" because of the Egyptian Revival features incorporated in the architectural design, it’s a masterpiece of stonework and masonry, exemplifying its era.

The fort contains informative markers and displays, a touchable cannon and artillery crew display, and gun emplacements.  The interior features 19th century restored living quarters, a mock laboratory, and a 1950's era office furnished to resemble a research and development lab at the facility. Don’t miss the ramparts for a spectacular view of the New London Harbor!

Interactive Exhibits 

This one-of-a-kind visitor center museum depicts over 225 years of military history and technological advances from the Revolutionary War to the Cold War. Three-dimentional models, touch screen exhibits, extensive graphics, and text panels bring to life the September 6, 1781 attack by the British under the command of Benedict Arnold, the U-boat menace during World War II, the anti-submarine efforts during the Cold War, and more.
