The Giant's Causeway is an area of coastline in county Antrim. Its interlocking basalt columns, many of which are hexagonal, make it a spectacular place to visit. It is a UNESCO World Heritage Site.
The unusual formation of hexagonal, pillarlike structures, was formed over 50 million years ago by volcanic activity. Molten basalt was pushed through chalk beds, and as it cooled it contracted and fractured resulting in the shapes we see today.
Such unusual shapes and rock formations gave rise to legend, myth and folklore of giants and Fionn MacCool. The curious can find out more at the Visitor Centre
