The Giant’s Causeway is an extensive area covering about 40,000 interlocking basalt columns. It is spread over six kilometres along the northern coast of Northern Ireland, on the edge of the Antrim plateau. These stone pillars with up to seven irregular sides that point out of the cliff are just a spectacular sight.
This Causeway was formed some 50 million years ago as a result of a volcanic eruption that caused lava to flow towards the coast. When it came in contact with the sea, the lava cooled, forming layers of basalt columns. And because of the pressure between the columns, each of them sculpted into different shapes. Ever since it was first documented. in 1693, the Giant’s Causeway has been subjected to studies by geologists. It stands as a special place, not just for the formations but also for the grasslands close by. There were human settlements in the area during the 1800s, but it is now uninhabited. However, more than three lakh persons visit the site every year.
