In the fictional world of J. R. R. Tolkien, Moria, also named Khazad-dûm, is an ancient subterranean complex in Middle-earth, comprising a vast labyrinthine network of tunnels, chambers, mines and halls under the Misty Mountains, with doors on both the western and the eastern sides of the mountain range. Moria is introduced in Tolkien's novel The Hobbit, and is a major scene of action in The Lord of the Rings.
In much of Middle-earth's fictional history, Moria was the greatest city of the Dwarves. The city's wealth was founded on its mines, which produced mithril, a fictional metal of great beauty and strength, suitable for armour. The Dwarves dug too greedily and too deep for mithril, and disturbed a demon of great power: a Balrog, which destroyed their kingdom. By the end of the Third Age, Moria had long been abandoned by the Dwarves, and was a place of evil repute. It was dark, in dangerous disrepair, and in its labyrinths lurked Orcs and the Balrog.
Scholars have identified likely sources for Tolkien's Moria: he had studied a Latin inscription about a lost ring at the temple of Nodens in Gloucestershire, at a place called Dwarf's Hill full of old mine-workings. The name Moria, Tolkien wrote, echoed the name of a castle in a Norwegian folktale, while Gandalf's death and reappearance reminded critics of the resurrection and transfiguration of Jesus. The West Gate that the Watcher in the Water crashes closed behind the Fellowship recalled to commentators the Wandering Rocks of Greek mythology, and Odysseus's passage between the devouring Scylla and the whirlpool Charybdis. Finally, the Fellowship's entry into the darkness via the deadly lake by the West Gate, and its exit into the light via the beautiful Mirrormere, alongside Gandalf's death and reappearance, has been compared to a baptism, a ceremony that combines a symbolic death and the gift of new life.
Moria provided dramatic scenes in Peter Jackson's film The Lord of the Rings: The Fellowship of the Ring, inspired by Alan Lee's illustrations. Its multiple levels of tunnels and halls have served, too, as the basis for a variety of computer and board games.
