ПОЖАЛУЙСТА! Нужен перевод текста. The Giant's Causeway
What Is It?
The Giant's Causeway is Northern Ireland's most famous landmark. It has been an official UNESCO World Heritage Site since 1986. Formed between 50 and 60 years ago by the volcanic activity, the 'causeway' draws people from far and wide to this corner of the North Antrim. This unique place occupies approximately 70 ha of land and 160 ha of sea. It is made up of some 40,000 massive hexagonal black basalt
columns which are packed tightly together and stick out of the sea. Some of the columns have four, five, seven and eight sides. The tops of the columns form stepping stones that lead from the cliff foot and disappear under the sea.
What Does the Legend Say?
The legend goes that the mythical Irish giant Finn MacCool built the causeway to Scotland and battle with the giant called Benandonner. When he got there, he found that the Scottish giant was asleep but also far bigger than himself, so Finn returned back across the causeway. When Benandonner woke up, he came across the causeway and was intent on fighting Finn. Finn's wife dressed up her husband as a baby. So when Benandonner arrived she said Finn wasn't at home. She also asked the giant to be quiet not to wake up the baby. When Benandonner saw the baby he decided that if the baby was that big, Finn must be massive. So he turned tail and fled back across the causeway ripping it up as he went. All that remains are the ends, here at the Giant's Causeway and on the island of Staffa in Scotland where similar formations are found.
A Wonder of the World?
In the past the causeway became widely known as the "The Eighth Wonder of the world" when large numbers of visitors came to view it from the 1700s. Perhaps now there is a chance it could be officially recognised as such a wonder.
In 2008 the Giant's Causeway was nominated one of the world’s seven natural wonders. The new seven wonders of the world were announced in Lisbon, Portugal in July 2007 and the new “Seven Wonders of Nature” as they are officially called were launched. These are currently being balloted and the chosen will be announced in 2010.
