A second place in the 1,000 places to see before you die calendar was Northern Ireland’s “otherworldly Giant’s Causeway.” These interlocking basalt columns are the result of volcanic fissure eruption some 50-60 million years ago. UNESCO called the regularly shaped polygonal columns off the coast of County Antrim near Bushmills:
40,000 massive black basalt columns sticking out of the sea…
The massive columns gave rise to legends of giants (maybe) and you can read a version at the link to Wikipedia. The columns disappear under the sea, and emerge again at Fingal’s Cave on the Scottish isle of Staffa.
The Giant’s Causeway “…appear like stone honeycombs or remnants of ancient columns.”
