Nestled high above the Thames River in Groton, Connecticut, Fort Griswold Battlefield State Park offers a poignant and picturesque journey back to the Revolutionary War.

Birdwatchers will delight in the calls of Carolina Wrens and Song Sparrows, while observant eyes may even catch a glimpse of an Eastern Red-backed Salamander or the playful antics of an Eastern Gray Squirrel. The park also features the Monument House Museum, which offers compelling exhibits and artifacts from the Revolutionary War era, and the restored Ebenezer Avery House, providing further historical immersion.

Fort Griswold's construction began on December 5, 1775, and was completed in 1778, serving as a vital defense for New London and the Thames River during the American Revolutionary War. On September 6, 1781, the fort became the site of the infamous Battle of Groton Heights, where British forces, led by the traitor Benedict Arnold, attacked and massacred the American defenders. To commemorate the 88 American patriots who died in this brutal battle, the impressive 135-foot Groton Monument was erected between 1826 and 1830, standing as the oldest monument of its type in the country. The site was officially designated as Fort Griswold Battlefield State Park in 1953, preserving this significant piece of national heritage for future generations.
