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.
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.
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.
