View of ancient volcanic basalt columns with geometric shapes at the Giant's Causeway, located in County Antrim on the coast of Northern Ireland.

---

Stretching from the cliff face of a volcanic plateau out into the sea, the Giant's Causeway includes around 40,000 interlocking basalt columns, the result of a volcanic eruption during the Paleocene Epoch some 50 to 60 million years ago. The unique natural formation was declared a UNESCO World Heritage Site in 1986.
