J. R. R. Tolkien's The Fall of Gondolin is one of the stories in The Book of Lost Tales which formed the basis for a section in his later work, The Silmarillion. A stand-alone, book-length version of the story was published in 2018. The Fall of Gondolin is one of three stories from the First Age of Middle-earth to be published as a stand-alone book: the other two are Beren and Lúthien and The Children of Húrin.
