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.
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.
