The remains of a portal tomb with a nearby burial chamber probably constructed using parts of the original tomb is located near Carnaghan (SW part of the island).  A 15th century castle stands on a cliff overlooking Lough Swilly. The island's Presbyterian Church is one of the smallest of the surrounding area (just some 14 families are members of it); its Catholic church, entitled to Our Lady of Lourdes, was built in 1932.
