Towers of the Teeth

The Towers of the Teeth (or Teeth of Mordor) were two towers situated on either side of the Black Gate. The two towers, Carchost and Narchost, stood on either side of Cirith Gorgor between the Ephel Dúath and the Ered Lithui.
== History ==
Originally built by Men of Gondor following the downfall of Sauron at the end of the Second Age, Gondor maintained garrisons in the Towers to prevent the return of evil to Mordor. Following the Great Plague evil crept back into Mordor, although the Towers were once again manned during the Wainrider War. After this the Towers of the Teeth were again abandoned and fell into ruin, eventually claimed by the servants of the Dark Lord. They were repaired and fortified, and were incorporated into the defenses of the pass and gate.
Narchost stood at the western end of the Gate, and Carchost at the eastern end. Frodo, Sam, and Gollum beheld these towers and the Black Gate between them as they disputed the best passage into Mordor, and it was before these towers that the Captains of the West and their host later made their last stand against the forces of Sauron. The towers were destroyed with the defeat of Sauron in TA 3019, upon the destruction of the One Ring.
