Ballylumford Dolmen is situated on Islandmagee, County Antrim, Northern Ireland, near the north-west tip of the Islandmagee peninsula and near Ballylumford power station.[1] It is known locally as the "Druid's Altar", and could be 4000 years old, or the remains of an even earlier passage grave. The dolmen consists of four upright stones, with a heavy capstone and a fallenstone within the structure. This may have been put there to block the entrance to the tomb. The dolmen is in the front garden of a house.[2][3] A wall plaque at the site describes the dolmen as a single chambered grave erected about 2000-1600 BC. Local finds indicate occupation of the neighbourhood during the Bronze Age.[4]
