Barad-dûr

Built on a spur of the Ered Lithui, and fashioned by the power of Sauron's Ruling Ring, Barad-dûr consists of a great central tower with nine radial towers connected to it by fortified bridges. Once the seat of Sauron's power, Barad-dûr fell when Isildur cut the Ring from Sauron's hand. Orcs and Trolls controlled the area, and no Man visited Barad-dûr since the Plague until Sauron returned from Dol Guldur in 2951 T.A..
