Description

The Giant's Causeway is an area of about 40,000 interlocking basalt columns the result of an ancient volcanic eruption. It is located in County Antrim on the north coast of Northern Ireland about three miles (4.8 km) northeast of the town of Bushmills.
It was declared a World Heritage Site by UNESCO in 1986, and a national nature reserve in 1987 by the Department of the Enviroment for Northern Ireland. In a 2005 poll of Radio Times readers, the Giant's Causeway was named as the fourth greatest natural wornder in the United Kingdom. The tops of the columns form stepping stones that lead from the cliff foot and disappear under the sea. Most of the columns are hexagonal, although there are also some with four, five, seven or eight sides. The tallest are about 12 metres (39 ft) high, and the solidified lava in the cliffs is 28 metres (92 ft) thick in places.
