Gorgoroth, also called the Plateau of Gorgoroth, is a fictional place in J. R. R. Tolkien's Middle-earth. It is a plateau in north-western Mordor in the midst of which stands the volcano Mount Doom. To the east of Mount Doom upon a spur of the Ered Lithui, Sauron constructed his fortress of Barad-dûr. During the War of the Ring, Gorgoroth was the location for the mines and forges that produced Mordor's arms and armour.
