The Groton Monument was built between 1826 and 1830, and is the oldest monument of its type in the country. Built of granite quarried locally, the Monument stands 135 feet tall with 166 steps. There is a marble memorial plaque with the names of the defenders who fell during the Battle of Groton Heights on September 6, 1781.
