Ballylumford Dolmen

Portal tomb on the Islandmagee peninsula, County Antrim, Northern Ireland, situated in a private front garden near Ballylumford power station [1] [2]. 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 [1] [3]. A wall plaque dates it to approximately 2000-1600 BC, though it could be the remains of an even earlier passage grave [1]. It is a State Care Historic Monument in the townland of Ballylumford [1].
