Northern Ireland: the Giant's Causeway
The Giant's Causeway is on the north-east coast of Northern Ireland. It is a mass of stone columns made by volcanic lava about 50 million years ago, and many legends have grown up around it.
The best-known legend is a lively one. The Irish giant Finn McCool laid this stone road across the sea to go and fight a Scottish giant, but when he saw how much bigger his rival was, he ran home and got his wife to dress him up as a baby. The Scottish giant took one look at the huge "baby", decided the father must be terrifying, and fled back to Scotland, smashing the road as he went. Geologists say the lava simply shrank and cracked as it cooled, forming the columns.
