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.
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.
