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.
And that's only half of it. This one patch of ground has lived four industrial lives. It built steel cargo ships in the First World War. It became one of the most advanced fish plants in America in 1927. It launched submarines in the Second World War — the boats that made Groton the Submarine Capital of the World. And in 1946 it started brewing penicillin by the ton. Ships, fish, submarines, medicine — the same riverbank, reinvented again and again.
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.
