Groton Congregational Church

Groton Congregational was established in 1702. Its minister, Rev. Aaron Kinne, served as the chaplain for the American forces during the Battle of Fort Griswold, on September 6, 1781. Most adult male members of the church perished at the battle. The current building is the fourth meeting house, which was constructed in 1902 and is listed on the National Register of Historic Places. The sanctuary is comprised of polished oak; Moller Pipe Organ; original chandeliers; and stained-glass windows, most notably The Avery Memorial Window.
