Teeth of Mordor

The Teeth of Mordor (or Towers of the Teeth) are two fictional towers situated on either side of the Black Gate of Mordor in J. R. R. Tolkien's Middle-earth. The towers&mdash;known individually as Carchost and Narchost&mdash;were originally constructed by the men of Gondor after Sauron's defeat in the Second Age, but were taken over by Sauron in the later Third Age long after they had been abandoned.

Tolkien's writings leave it unclear which tower was located on which side of the Morannon. However, Carchost appears to have stood to the eastern side and Narchost on the western side. Carchost is a Sindarin name that means "Tooth Fort", a compound of carch (meaning 'tooth or fang') and ost (meaning 'fortress'). Narchost is a Sindarin name that means "Fire Fort".

The towers were presumably destroyed in the War of the Ring with the defeat of Sauron following the destruction of the One Ring. Their collapse is shown in Peter Jackson's interpretation of Return of the King.
