Legend says that an ancient Irish giant called Fionn mac Cumhaill built stepping stones
off the coast of County Antrim in Northern Ireland to fight a Scottish
giant called Benandonner, who was coming to meet him from the other side
of the Irish Sea. Today, you can see those stones, which are actually
about forty thousand giant black columns that were formed by an ancient
volcanic eruption and that lead from the base of a cliff and disappear under the sea. The Giant’s Causeway is often considered
one of the natural wonders of the world. It is one of the most popular
tourist sites in Ireland, attracting almost a million visitors a year.
