Groton's stories run to the water. The town took its name from Groton, the Suffolk manor of John Winthrop, who led the founding of the Massachusetts Bay Colony; the river it sits on, the Thames, is named for London's — though locals say it plainly, "Thaymes," not the English way. They'll tell you Groton built more than seventy submarines for the fleet in a single world war, and that for decades the new boats slid down the ways straight into the Thames, the way the Nautilus did in 1954. Down at Fort Griswold every September, the town still gathers to remember the men who fell in 1781. The harbor that made Groton a target in the Revolution is the same deep water that made it the Submarine Capital of the World — the whole story turns on that one stretch of river.
The Submarine Capital of the World — where the first nuclear submarine slid into the Thames in 1954. Groton, Connecticut sits on the east bank of the Thames River, on a deep-water harbor that has been building and berthing ships for three centuries. It is the place where the world's first nuclear-powered submarine, the Nautilus, was launched in 1954 — and where she still floats today, open to anyone who wants to walk her decks at the Submarine Force Museum. Groton has earned the title Submarine Capital of the World for a simple reason: the boats that disappear beneath the world's oceans have been built and based here for generations. But the town's salt runs deeper than steel — back to a 1705 shipbuilding-and-whaling village, and to the hallowed ground of Fort Griswold.
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.
