But the buildings stood. In 1946 Pfizer bought the yard for under a million dollars and filled those same halls with towering fermentation tanks. Groton went on to brew penicillin by the ton — enough to supply most of the United States and half the world — and helped drive the price of the miracle drug from twenty dollars a dose down to under two cents. The antibiotics perfected here traveled with medics to the front-line MASH tents of Korea, and then reached everyone else. Today that rocky point on Eastern Point holds a gleaming research campus where nearly every one of the company's medicines is shaped, in part. From a fish dock to a cure that circled the globe — the same half-mile of Thames riverbank.
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.
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.
