Rock formation on the Antrim coast of Northern Ireland
The Giant's Causeway is an area of approximately 40,000 interlocking basalt columns, the result of an ancient volcanic fissure eruption, part of the North Atlantic Igneous Province active in the region during the Paleogene period. It is located in County Antrim on the north coast of Northern Ireland, about three miles northeast of Bushmills.
