The Giant's Causeway.

The Republic of Ireland is a sovereign state covering approximately five-sixths of the island of Ireland, off the coast of north-west Europe. The state's constitutional name is Ireland (in the Irish language: Éire) and this is how international organisations and residents usually refer to the country. It is a member of the European Union, has a developed economy and a population of slightly more than 4.2 million. The remaining sixth of the island of Ireland is known as Northern Ireland and is part of the United Kingdom.
