This outer defense-work of the city of Minas Tirith was constructed after Ithilien fell under the shadow of the Enemy. It was a great wall, over 10 leagues in length, encircling the hitherto defenseless townlands of the city. Nonetheless, the defensive value of the Rammas was open to doubt: for at its furthest point, it was some four leagues from the city and thus could not be manned in strength, since the main defense of Minas Tirith lay in its city-walls and Great Gate. Moreover, defenders on the out-wall might find themselves cut off from retreat were a breach to be made and the gap stormed in strength. At best, Rammas could only serve to delay unsupported Cavalry forces or foot soldiers without breaking tools. The Rammas was repaired at the time of the War of the Ring, but was easily breached by by the armies of Sauron under their Black Captain on March 13th, 3019.
