Ruud Streefkerk

We are on the Atlantic coast in Northern Ireland. The stones are overgrown with moss and algae. This district is named after two of Northern Ireland's most visited tourist attractions: the Giant's Causeway on the north coast, consisting of some 40,000 basalt columns created by a volcanic eruption some 60 million years ago, and a World Heritage Site since 1986. And secondly  to the Glens of Antrim: nine river valleys that descend from the Antrim Plateau to the coast. The Glens are also a major tourist attraction in northern Antrim.
