What's with Gungywamp? Tucked in the woods inland from the harbor is one of the strangest-looking places in Connecticut — a hundred-acre site of stone chambers, old foundations, and a double ring of laid stones called Gungywamp, now a State Archaeological Preserve. Because the chambers are low and stone-roofed, and because one of them catches a shaft of sunlight through a small opening at the equinox, the site has drawn a century of romantic theories — Irish monks, Norse voyagers, ancient astronomers. The archaeology tells a quieter story: Native people used this land for thousands of years, and the stone structures themselves are colonial-era — root cellars that worked like early refrigerators, and a double stone circle that was almost certainly a mill for grinding bark or grain. The equinox light through the chamber window is real, and genuinely lovely; the lost civilization is not. Gungywamp is Groton's reminder that the most interesting history is usually the true one.
The Pequot people lived along these coves and rivers long before the colonists — their presence at the Gungywamp site inland reaches back thousands of years. Groton was settled as part of New London and incorporated as its own town in 1705, growing into one of New England's busy Thames-River shipbuilding and whaling ports. On September 6, 1781, that prosperity made it a target: a British force under the turncoat Benedict Arnold raided the Thames, and at Fort Griswold roughly 165 Connecticut militia under Colonel William Ledyard made an outnumbered last stand. They were overwhelmed, and most of the defenders fell. The town never forgot them — in 1830 it raised a 135-foot granite obelisk, the Groton Monument, over the battlefield to the dead. A U.S. Navy yard followed on the Thames in 1868, and in the twentieth century Groton became the cradle of the American submarine.
Why People Visit Groton Connecticut
Groton draws people who love the sea and the stories that come with it. It is the Submarine Capital of the World, with the first nuclear submarine open to walk through; it is a Revolutionary battlefield with a monument to its fallen; and it is a working shoreline of deep harbor, forts, beaches, and lighthouse points. Visitors come for the rare combination — naval history you can stand inside, colonial history you can climb, and a Connecticut coast you can walk all in one town on the Thames.
