The Dolmen can be found on the north east shore of Loughinisland Lake, within sight of Loughinisland Church. A slightly displaced capstone covers a rectangular chamber of which three side stones survive. An early account suggests that this was formerly inside a large circular cairn and approached through a lintelled passage, so it may be the remains of a passage tomb. It is famous as the platform from which Thomas Russell addressed a crowd of United Irishmen in 1803, after the main 1798 rising.
