Groton Monument

Groton Monument is a 41-meter-tall granite obelisk with a pyramid-shaped iron cap located in Groton, Connecticut. The structure stands within Fort Griswold Battlefield State Park and rises prominently above the surrounding landscape, visible from various points across the grounds.

The obelisk was completed in 1830 and honors American soldiers who died during the Battle of Groton Heights on September 6, 1781. This date marks a significant moment in the American Revolution when a British attack on the local fort resulted in heavy losses on both sides.

The monument displays plaques with the names of 88 American soldiers, including African American troops, who died defending Fort Griswold. These names make the personal stories of the place visible and honor individuals from different backgrounds who fought together.

The site is open from late May through early September and allows visitors to climb the monument and explore the adjacent museum. Access is through Fort Griswold Battlefield State Park, which provides parking and visitor information stations throughout the grounds.

Lightning struck the monument in 1918, destroying its iron cap and damaging the adjacent museum building. The structure survived this impact and today stands alongside the restored museum, which displays Revolutionary War artifacts.
