The Giant’s Causeway is a World Heritage Site on the North Antrim Coast of Northern Ireland
It is made up of around 40,000 large stone columns , which lie at the bottom of a cliff and make a path that leads out of sea. Although, according to science, these columns were created by volcanic activity around sixtty million years ago, a legend says that the Causeway is what is left of a path that a giant built to join Ireland and Scotland.
In one story, the Irish giant, Fionn mac Cumhaill, built the Causeway to walk over to Scotland and fight the Scottish giant, Benandonner. However, when he went to meet Benandonner and saw that he was twice his size, he changed his mind. He dressed up as a baby and waited. When Benandonner saw him, he run away because he thought that the father of such a large child would be ready enormous. He destroyed the Causeway behind him, leaving only the stones we see today.
Today the Causeway is a huge tourist attraction. The area is also a nature reserve, and visitors can see unusual plants and rare birds and animals.
