Sitting at a strategic position along the Thames River, water has played a significant part in the growth of Groton, Connecticut. Visit Fort Griswold, a Revolutionary War era base built to defend the port of New London, most infamously known as the site of the betrayal of American forces by Benedict Arnold. Groton is also the "Submarine Capital of the World," home to the US Navy's main submarine base, as well as the Submarine Force Museum, where visitors can board the first nuclear submarine.
