Giant Cuaseway , (85 images) For centuries countless visitors have marvelled at the majesty and mystery of the Giants Causeway. At the heart of one of Europe's most magnificent coastlines its unique rock formations have, for millions of years, stood as a natural rampart against the unbridled ferocity of Atlantic storms. The rugged symmetry of the columns never fails to intrigue and inspire our visitors. To stroll on the Giants Causeway is to voyage back in time.Your imagination will travel along stepping stones that lead to either the creative turbulence of a bygone volcanic age or into the mists and legends of the past.The Causeway proper is a mass of basalt columns packed tightly together. The tops of the columns form stepping stones that lead from the cliff foot and disappear under the sea. Altogether there are 40,000 of these stone columns, mostly hexagonal but some with four, five, seven and eight sides. The tallest are about 40 feet high, and the solidified lava in the cliffs is 90 feet thick in places. Photo: Knut Skaar
