In 1844 a souterrain was discovered, known to the islanders as the House Of Fairies. It consists of a lintelled passage, some 9m long with at least one known lateral branch. The stones used in its construction are large, with massive walls converging towards to the top to accommodate the lintels. The structure which has been excavated numerous times since 1844 with finds giving a suggested date back to the first or early second millennium AD. A few decorated potsherds are similar to standard Iron Age finds uncovered elsewhere in the Western Isles.
