Fingal's Cave

Fingal's Cave, a sea cave located on the uninhabitated island of Staffa, Scotland, consists of a large series of hexagonally shaped basalt columns. It was named after the hero of an 18th century Scottish epic poem by James Macpherson. Because of its arched ceiling, it produces eerie echoing sounds, which prompts its name, "Uamh-Binn," which means "cave of melody" in Gaelic.
