The Gungywamp complex in northwest Groton is a state-owned property stewarded by the Nature Center. It features meandering stone walls, stone chambers, and the remains of scattered colonial sites amongst interesting geological features and irregular ridges, bogs and swamps. Paleo and woodland Native American artifacts (stone implements and pottery shards), colonial and Early American artifacts have been found on the site, but the usage of some of the structures still remains a mystery. DPNC leads regular hikes on the property, and private walks are available by appointment. In 2022 DPNC nominated the property for listing on the State Register of Historic Places as an archeological preserve.
