Fingal's Cave

The columns inside this cave on the uninhabited island of Staffa were poured, geologically speaking, at the same moment as the more famous ones across the water in Ireland. Around 60 million years ago, a single vast lava flow cooled slowly enough that it cracked into regular hexagonal columns as it contracted — the same process, the same flow, on both sides of what's now open sea. The Giant's Causeway and this cave are, quite literally, two exposed cross-sections of one geological event.

The name people know it by is younger than it sounds. The story of the giant Fionn mac Cumhaill building a causeway to Scotland is old Gaelic tradition, but ‘Fingal’ and the specific cave name came from James Macpherson's hugely popular 18th-century poetry cycle, published from 1760 onward, which claimed to translate ancient Gaelic epics but was substantially Macpherson's own literary invention layered onto real folklore. Naturalist Joseph Banks, visiting in 1772 fresh off Macpherson's fashionable reworking, is generally credited with attaching that name to the cave for an English-speaking audience — meaning the ‘ancient legend’ visitors hear about today is a real myth wearing a name coined by 18th-century marketing.

What's not exaggerated is the acoustics. The cave's regular, arched, nave-like interior amplifies the boom and hiss of the Atlantic swell rolling in, and it was exactly that sound — not the visuals — that stopped Felix Mendelssohn on his 1829 visit. He sketched the opening theme of what became his Hebrides Overture on the spot, turning a sea cave's echo into one of the best-known orchestral works of the Romantic era.
