Rammas Echor
From the One Wiki to Rule Them All, the Lord of the Rings Encyclopedia.
Rammas Echor was a great ancient wall that surrounds Minas Tirith and encloses the Pelennor Fields. It was built after Minas Ithil fell and was renamed Minas Morgul to resist invasions. The wall was repaired during the time of the War of the Ring by Denethor II, but did little to resist the forces of Sauron, led by the Witch-king of Angmar. Interestingly, the videogame The Lord of the Rings: The Return of the King depicts a gate of a wall in the level, "The Southern Gate".
