The Giant's Causeway gained its name due to the Irish myth surrounding its formation. Most likely because of the Causeway's uniform and unusual shape, the people of Ancient Ireland created a fable to understand how the Causeway was created. As lava cools, cracks within the material grow most efficiently at certain angles. In many places worldwide, such as Devils Tower in Wyoming and the Giant's Causeway in Northern Ireland (image), ancient lavas cooled into hexagonal blocks or columns. It is 2 miles (3km) from Bushmills village, 11 miles (18km) from Coleraine and 13 miles (21km) from Ballycastle.
