The concert overture The Hebrides (/ˈhɛbrᵻdiːz/; German: Die Hebriden), Op. 26, also known as Fingal's Cave (Die Fingalshöhle), was composed by Mendelssohn in 1830. The second edition of this Overture was completed on June 1832. The piece was inspired by Mendelssohn's visit to Fingal's Cave on the island of Staffa, located in the Hebrides archipelago off the west coast of Scotland. As was common in the Romantic era, this is not an overture in the sense that it precedes a play or opera; it is a concert overture, a stand-alone musical selection, and has now become part of standard orchestral repertoire. The piece was dedicated to King Frederick William IV of Prussia (then Crown Prince of Prussia).
Mendelssohn's first visit to England in 1829 resulted from invitations by Sir George Smart and the Philharmonic Society. Following his tour of England, Mendelssohn proceeded to Scotland, where he began work on his Symphony No. 3, Scottish. He was engaged on a tour of Scotland with his travelling companion Karl Klingemann when he sent a postcard to his family with the opening phrase of the overture written on it. In a note to his sister, Fanny Mendelssohn he said: "In order to make you understand how extraordinarily the Hebrides affected me, I send you the following, which came into my head there." The cave at that time was approximately 35 feet (11 m) high and over 200 feet (61 m) deep, and contained black basalt pillars.
