Collection: Groton Connecticut

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.

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.

Today the deep harbor that drew the shipwrights and the Navy still defines Groton. The Submarine Force Museum berths the Nautilus on the Thames; Fort Griswold Battlefield State Park keeps the monument and the memory; and the coast opens out at Bluff Point, Eastern Point Beach, and Avery Point, where the last lighthouse built in Connecticut still stands above Long Island Sound. Groton is Connecticut's hard-edged maritime soul — monuments, harbors, and the deep water that made all of it possible.

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.

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.

Our Groton logo carries the same emblem every Merlin Classics Connecticut town wears — an oyster above "Connecticut, Est. 1636," the colony's founding year, rendered in hand-printed black and white with a worn, vintage feel. The oyster is the shoreline state's mark, the through-line that ties Groton to every other Connecticut town we make. What makes this one Groton is everything around it: the submarine harbor, the monument on the heights, the deep Thames water. On a tee or a cap it reads less like a souvenir and more like a small piece of the Connecticut coast — Est. 1636, worn plain.

Today Groton is known the world over for its submarines, and at home for its monument, its harbor, and its shoreline parks. Its story blends Pequot beginnings, colonial shipbuilding, Revolutionary sacrifice, and the nuclear age that began on its waterfront. Our Groton designs gather that identity into wearable form — the Submarine Capital, the Thames, the Connecticut coast. Explore the collection and carry a little of Groton's depths with you.

Groton Connecticut — Travel Guide

Visiting Groton Connecticut Today

Groton sits on the east bank of the Thames River where it meets Long Island Sound, in New London County. The landmarks cluster along the waterfront — the Submarine Force Museum and the Nautilus near the river, Fort Griswold on the heights above the harbor, and a string of shoreline parks out toward the Sound. Summer is the peak window for the museum, the beaches, and the trails; spring and fall are quieter and good for the forts and the coast walks. September 6, the anniversary of the Battle of Groton Heights, is a solemn date in town.

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.

Kindred Cities

Greetings to visitors from Portsmouth, England and Halifax, Canada — fellow navy towns that send ships and crews to sea.

Few towns wear the navy as plainly as Groton, and Portsmouth and Halifax are its natural company. Portsmouth has been the Royal Navy's home for centuries, keeper of HMS Victory and the historic dockyard; Halifax anchors Canada's Atlantic fleet; Groton is the Submarine Capital of the World, where Electric Boat builds the boats and the base sends them to sea. Steel hulls and saltwater service, all three.

Groton favours anyone raised in a navy town: a working submarine base on the river, a shipyard that has launched the fleet for over a century, and the kind of harbour pride that comes with sending people to sea. Come and visit us soon.

When you plan the trip, the Town of Groton and the Connecticut Office of Tourism are the place to start.
