Belfast (Northern Ireland's Antrim Coast and Giants Causeway), is a UNESCO World Heritage Site

The Giant's Causeway and Causeway Coast is the only UNESCO world heritage site in Northern Ireland and its most visited attraction.  It was inscribed in 1986.  The dynamic coastal landscape is made up of 40,000 massive layered black interlocking, basalt, polygonal columns rising from the sea, rugged cliffs, fascinating geographical antiquities - the result of intense volcanic and geographical activity-displaying 60 million year-old legacy to the cooling and shrinking of successive lava flows - on the Antrim plateau of Northern Ireland.  They are a rampart against ferocious Atlantic storms.

Galway's (Ballyvaughan) Ailwee Caves

Galway is the capital of the west of Ireland and - not far from Galway - are the impressive Ailwee caves the most important caves in Ireland.  The story of Ailwee began millions of years ago.  It is a stunning creation of nature formed by the melting waters of a prehistoric ice age.  The caves, carved out of limestone, cut into the heart of the mountain, and is an underground treasure.
