The Tower of Cirith Ungol

A watchtower on the border of Mordor. The Tower of Cirith Ungol was located high in the Mountains of Shadowoverlooking the pass that was called Cirith Ungol — the Pass of the Spider — because the Great Spider Shelob dwelled there. At the top of the pass was a cleft with two great horns of rock on either side. On the northern horn stood the Tower of Cirith Ungol, built up against the eastern face of the rock. The Tower of Cirith Ungol was made of black stone. It had three tiers, each set back from the next like steps. The sheer sides faced northeast and southeast and formed a bastion pointing eastward. At the top of the Tower was a round turret that could be seen above the pass.
A road ran down from the pass and skirted the Tower alongside a sheer precipice before turning southward to join theMorgul-road. The Tower of Cirith Ungol was surrounded by an outer wall that was 30 feet (9.1 m) high. The sides of the wall were smooth. At the top was overhanging stonework that prevented anyone from climbing over it.
The main gate was in the southeastern side of the wall. It was guarded by the Two Watchers — hideous statues seated on thrones. Each Watcher had three joined bodies facing inward, outward, and toward the other. The description in the Book is as follows:
"They were like great figures seated upon thrones. Each had three joined bodies, and three heads facing outward, and inward, and across the gateway. The heads had vulture-faces, and on their great knees were laid clawlike hands. They seemed to be carved out of huge blocks of stone, immovable, and yet they were aware: some dreadful spirit of evil vigilance abode in them. They knew an enemy. Visible or invisible none could pass unheeded. They would forbid his entry, or his escape."
They thus had a kind of "psychic barrier" that barred the gate. Sam Gamgee had to overcome this obstacle while searching for his master Frodo Baggins. Sam did so by using the phial of Galadriel, which overcame their will and allowed him to pass. As soon as he was through, however, they sounded an alarm. It is not known if the Watchers were built by men of Gondor, as was the Tower itself, or if it had been added later by Sauron. Certainly, the spirit that dwelt within them must have come later, as it was clearly identified as being evil.
Within the outer wall was a paved courtyard. There was a great door on the southeastern side of the Tower of Cirith Ungol. A passageway ran back through the Tower with rooms on either side. At the far end was the arched door of the Undergate — a back entrance to the Tower that opened onto a tunnel that joined with Shelob's Lair.
To the right of the Undergate was a winding stairway to the upper levels of the Tower. At the top of the stairs was a domed chamber with doors facing east and west leading out onto the roof of the third tier. The roof was about 20 yards (18 m) across and was surrounded by a parapet. On the western side of the roof stood the turret of the Tower.
The turret had slitted windows facing westward and eastward through which torchlight glowed like red eyes. A winding stairway led up to a passage running through the middle of the turret. A trapdoor in the ceiling of the passage opened onto a large round chamber at the very top of the Tower of Cirith Ungol.
The Tower of Cirith Ungol was built by the Men of Gondor after Sauron was defeated in the War of the Last Alliance at the end of the Second Age. The Tower was the easternmost outpost of the defences of Ithilien. Its original purpose was to keep watch on the land of Mordor to ensure that no evil things escaped and to guard against the possibility of the Dark Lord's return. But over time, as Gondor's power declined, the vigilance on Mordor became lax and the Tower was deserted.
After the Lord of the Nazgûl returned to Mordor in T.A. 1980, the Tower came under his control. From Cirith Ungol, he led an assault on Minas Ithil, which was captured in 2002 and became his stronghold known as Minas Morgul. Sauron returned to Mordor in 2942, and he used the Tower of Cirith Ungol to prevent any of his slaves or prisoners from escaping from Mordor. A garrison of Orcs were stationed in the Tower, and at the time of the War of the Ring their captain was Shagrat.
On 13 'March' 3019, Shagrat brought Frodo Baggins through the Undergate to the Tower of Cirith Ungol and imprisoned him in the topmost chamber of the turret. Frodo was stripped and questioned mercilessly. Gorbag — an orc from Minas Morgul — coveted Frodo's *mithril* shirt and he fought Shagrat for it. The orcs of their two companies fought and killed one another until nearly all of them were dead.
Sam Gamgee came to the Tower of Cirith Ungol to rescue Frodo. He got past the Two Watchers by raising the Phial of Galadriel, but once he was through the gate the Watchers gave a terrible cry and an alarm bell rang in the Tower. Sam entered the Tower and encountered Snaga, who mistook Sam for a Great Elf-warrior and fled back up the stairs. Sam followed him to the roof of the third tier. There Sam confronted Shagrat, who fled with the *mithril* shirt.
Sam entered the turret in search of Frodo, but he could not find a way to the uppermost chamber until he saw Snaga climb up through the trapdoor in the ceiling. He followedSnaga, and when he saw the orc whipping Frodo he charged at him, and Snaga fell through the trapdoor to his death.
Sam returned the Ring to Frodo and they escaped from the Tower disguised in Orc armour and livery. They used the Phial to pass the Watchers, and the archway collapsed behind them. As they fled, a Winged Nazgûl descended from the sky and perched on the wall of the Tower of Cirith Ungol, now in charge.
The Tower of Cirith Ungol has been illustrated by artists such as John Howe, the Brothers Hildebrandt, and Alan Lee. The image by Tim and Greg Hildebrandt features an eruption of Mount Doom in the background and one of the Hobbits looking at the tower from a rock spire in the foreground. The Two Watchers are not depicted although the castle-like structure of the tower shows a gate.
