Gates of Mordor by Brothers Hildebrandt.
The Gate of Mordor (also the gates of Mordor and once - thus called by Elrond in the Council of Elrond - the Black Gate 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.
