The Gungywamp site is located in Groton, Connecticut. It has two separate areas called the South and North Complexes. Each complex has a high cliff, a swamp and brook in conjunction with man-made stone structures and features. Archaeological excavations at the site have confirmed the presence of Native Americans at the site over the past 4,000 years, and the settlement of the area by white farmers after 1780. There are two stone rows each with approximately twenty nine stones. Although some stones are currently missing they have been accounted for by the sockets. Each row is oriented north. Each row has an elliptical arch or crescent curve. The two rows are in the vicinity of the swamp. North Row is in deteriorated condition. By comparison the South Row is in good condition despite missing a few end stones. This suggests the North Row is much older than the South Row. The South Row has a bird effigy, stone paving, a rubbing stone, and a post hole.
