What is Giant's Causeway?
The Giant's Causeway is an area of about 40,000 interlocking basalt columns, the result of an ancient volcanic eruption. It is also known as Clochán an Aifir or Clochán na bhFomhórach in Irish and tha Giant's Causey in Ulster-Scots.
The Giant's Causeway northern Ireland, renowned for its polygonal columns of layered basalt, is the only UNESCO World Heritage Site in Northern Ireland and in 2015 was awarded the UKs Best Heritage Attraction at the British Travel Awards.
Resulting from a volcanic eruption 60 million years ago, this is the focal point of a designated Area of Outstanding Natural Beauty and has attracted visitors for centuries. It harbours a wealth of local and natural history.
Sea birds can be seen off the coast around the Causeway, with species such as fulmar, petrel and razor-bill being frequently observed alongside rare and unusual plant species on the cliffs and nearby rock formations.
The Giant’s Causeway is also steeped in myth and legend. Some say it was carved from the coast by the mighty giant, Finn McCool who left behind an ancient home full of folklore. Look out for clues of his existence including The Giant’s Boot and Wishing Chair.
Rising and blending into the landscape, with walls of glass, basalt columns and a state of the art interior designed by award winning architects Heneghan-Peng, The Giant’s Causeway Visitor Centre is truly innovative. The grass roof offers 360 degree views of the Causeway coastline. Explore the interactive spaces, watch Finn McCool on the big screen and unlock the secrets of this inspirational landscape.
Geological History
The unusual formation was born of natural processes during the Paleogene (65-23 million years ago), when Northern Ireland was subject to powerful volcanic activity. During this period, molten basalt came into contact with chalk beds, forming a lava plateau. When the lava cooled quickly, the plateau contracted and cracked, forming 40,000 hexagonal columns of varying heights that look like giant stepping stones. The largest stand almost 36 feet tall.
History
According to legend, an Irish giant by the name of Fionn mac Cumhaill constructed the causeway himself so that he could skip over to Scotland to defeat his Scottish rival, Benandonner. Apparently, while in transit to Scotland, Fionn fell asleep, and Benandonner decided to cross the causeway to look for his competitor. To protect her slumbering slumbering husband, Fionn’s wife gathered him up and wrapped him up in cloth in order to camouflage him as their child. When Benandonner made it to Northern Ireland tour he saw the large infant and could only imagine how big Fionn must be. Frightened, Benandonner fled back to Scotland. But the causeway remained.
Although the phenomenon of basalt columns is relatively rare, there are a few dramatic examples of the rock formation found around the world, including Fingal’s Cave in Scotland, Los Prismas Basálticos in Mexico, and the Devil’s Postpile in California.
Giant's causeway location
It is located in County Antrim on the northeast coast of Northern Ireland, about three miles (4.8 km) northeast 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 or eight sides. The tallest are about 12 metres (39 ft) high, and the solidified lava in the cliffs is 28 metres (92 ft) thick in places.
Much of the Giant's Causeway and Causeway Coast World Heritage Site is today owned and managed by the National Trust and it is one of the most popular tourist attractions in Northern Ireland. The remainder of the site is owned by the Crown Estate and a number of private landowners.Tours of Ireland
