Cirith Ungol


 * The pass through the western mountains of Mordor and one of two entrances to that land from the West, along with the Morgul Pass. The name is Sindarin for Spider's Cleft, or Pass of the Spider, presumably referring to the guardian of the pass, Shelob, the daughter of the ancient spider Ungoliant.


 * The Pass of Cirith Ungol was high above the Morgul Pass, on the northern side of the Morgul Vale. In Mordor, the road from Cirith Ungol came down to join the Morgul-road. These routes were guarded by the Tower of Cirith Ungol, built by the Men of Gondor after the War of the Last Alliance, but occupied by Orcs at the time of the War of the Ring.


 * During the Quest of the Ring Frodo Baggins and Samwise Gamgee were led to this pass by Gollum to Torech Ungol, the lair of the giant spider-like creature Shelob who dwelt there, in order to get into Mordor.
