In J.R.R. Tolkien's legendarium, Gondolin is a secret city of Elves in the First Age of Middle-earth, and the greatest of their cities in Beleriand. The story of the Fall of Gondolin tells of the arrival there of Tuor, a prince of Men; of the betrayal of the city to the Dark Lord Morgoth by the king's nephew, Maeglin; and of its subsequent siege and catastrophic destruction by Morgoth's armies. It also relates the flight of the fugitives to the Havens of Sirion, the wedding of Tuor and the Elf Idril, and the childhood of their son Eärendil.
