The Giant’s Causeway is an area of about 40.000 interlocking basalt columns, the result of an ancient volcanic fissure eruption. It is located in County Antrim on the north coast of Northern Ireland, about 4.8 km northeast of the town of Bushmills.
Around 50 to 60 million years ago, Antrim was subject to intense volcanic activity. Highly fluid molten basalt intruded through chalk beds to form an extensive lava plateau. As the lava cooled, contraction occurred, with the cracks propagating down as the mass cooled, leaving pillarlike structures.
The discovery of the Giant’s Causeway is attributed to the Bishop of Derry who had visited the site in 1692. The site first became popular with tourists during the nineteenth century, particularly after the opening of the Giant’s Causeway Tramway.
Much of the Giant’s Causeway and Causeway Coast World Heritage Site is today owned and managed by the National Trust and it is one of the most popular tourist attractions in Northern Ireland.
