Ballylumford Dolmen

Portal tomb on the Islandmagee peninsula, County Antrim, Northern Ireland, situated in a private front garden near Ballylumford power station. Known locally as the Druid's Altar, it consists of four upright stones supporting a heavy capstone, with a fallen stone inside that may have blocked the tomb entrance. A wall plaque dates it to approximately 2000-1600 BC, though it could be the remains of an even earlier passage grave. It is a State Care Historic Monument in the townland of Ballylumford.
