Interlocking basalt columns in Ireland
The Giant's Causeway is an area of about 40,000 interlocking basalt columns, the result of an ancient volcanic fissure eruption.
Around 50 to 60 million years ago,[3] during the Paleocene Epoch, Antrim was subject to intense volcanic activity, when highly fluid molten basalt intruded through chalk beds to form an extensive volcanic plateau.
[13] Across the sea, there are identical basalt columns (a part of the same ancient lava flow) at Fingal's Cave on the Scottish isle of Staffa, and it is possible that the story was influenced by this.
Visitors can walk over the basalt columns that are at the edge of the sea, a half-mile walk from the entrance of the site.
Other features include many reddish, weathered low columns known as Giant's Eyes, created by the displacement of basalt boulders; the Shepherd's Steps; the Honeycomb; the Giant's Harp; the Chimney Stacks; the Giant's Gate and the Camel's Hump.

Basalt columns are a common volcanic feature, and they occur on many scales, because faster cooling produces smaller columns.
The most characteristic and unique feature of the site is the exposure of some 40,000 large, regularly shaped polygonal columns of basalt in perfect horizontal sections, forming a pavement.
Criterion (vii): The cliff exposures of columnar and massive basalt at the edge of the Antrim Plateau present a spectacle of exceptional natural beauty.
The Causeway itself is a unique formation and a superlative horizontal section through columnar basalt lavas.
