Science tells us that the Giant’s Causeway on the coast of Northern Ireland was formed by a giant lava flow formed by a volcanic eruption millions of years ago. Its basalt columns were perfectly formed as the lava dried, creating symmetrical hexagonal pillars in the form of a staircase. Wow, Mother Nature is quite the artist!
