Gate of Mordor

This article is about the pass in Mordor. For the MERP supplement, see Gates of Mordor (book).

The Gate of Mordor (also the gates of Mordor) was a term for the defended pass in the northwest of Mordor, and great Black Gate - the Morannon - that protected it. The Gates opened onto a narrow valley, Udûn, and were highly defensible. Indeed, they were only successfully assaulted once in their history, by the armies of the Last Alliance.
