The Giant's Causeway  is an area of about 40,000 interlocking basalt columns, the result of an ancient volcanic eruption. It is located on the northeast coast of Northern Ireland, about two miles (3 km) north of the town of Bushmills. It was declared a World Heritage Site by UNESCO in 1986, and a National Nature Reserve in 1987 by the Department of the Environment for Northern Ireland. In a 2005 poll of Radio Times readers, the Giant's Causeway was named as the fourth greatest natural wonder in the United Kingdom. The tops of the columns form stepping stones that lead from the cliff foot and disappear under the sea. Most of the columns are hexagonal, although there are also some with four, five, seven and eight sides. The tallest are about 12 metres (36 ft) high, and the solidified lava in the cliffs is 28 metres thick in places. The Giant's Causeway is today owned and managed by the National Trust and it is the most popular tourist attraction in Northern Ireland

Dunluce Castle is literally translated as the Hill fort of the fairy fort is one of the most extensive ruins of a medieval castle in Northern Ireland. It is located on the edge of a basalt outcropping in County Antrim, Northern Ireland and is accessible via a bridge connecting it to the mainland. It is between Portballintrae and Portrush. The castle is dramatically surrounded by terrifyingly steep drops either side, which would have been a very important factor to the early Christians and Vikings who were drawn to this place where an early Irish fort once stood. At one point, part of the kitchen next to the cliff face collapsed into the sea, after which the wife of the owner refused to live in the castle any longer. According to a legend, when the kitchen fell into the sea only a kitchen boy survived as he was sitting in the corner of the kitchen which did not collapse
