The Giant's Causeway, renowned for its polygonal columns of layered basalt, is the only World Heritage Site in Northern Ireland.

Weathered formations have created circular structures round a core of basalt which are known locally as "giant's eyes". Some other formations with popular names are the Chimney Stacks, The Harp, The Organ and the Camel's Hump.
