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.
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.
