Fingals Cave on the Isle of Staffa in the Inner Hebrides, Scotland.
The volcanic Staffa is famous for its spectacular hexagonal basalt columns. This cliff face is known as The Colonnade or The Great Face and it was these cliffs and caves that inspired Felix Mendelssohn's 'Hebrides Overture' which was premiered in London in 1832.
This cave became known as Fingal's Cave after the hero of a poem by the 18th century Scots poet, James Macpherson.
