Giant’s Causeway (Irish: Clochán an Aifir) is an area of about 40,000 interlocking basalt columns along on the coast of Northern Ireland.
Located in County Antrim, the causeway can be found about three miles (4.8 km) northeast of the town of Bushmills. This place, one of Northern Ireland’s most visited tourist attractions, continues to leave people marveled by the fact that it is a natural creation, not formed by human hands. 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.
Much of the Giant’s Causeway and Causeway Coast World Heritage Site is today owned and managed by the National Trust.
