Two great statues guarded the gate of the Tower of Cirith Ungol; each consisted of three joined bodies, with three heads – facing inward, outward, and against the gateway – and vulture-like faces and claws. They were known as the Silent Watchers, the Two Watchers, or simply the Watchers. Although they were carved out of stone, they seemed to have an awareness of their surroundings. No enemy was allowed to enter (or escape) unless his will was stronger than theirs; and if they did pass, an alarm would sound. Samwise Gamgee gained entry through the gates with the help of the Phial of Galadriel.
