But that shoulder, which rose to the height of the fifth wall, was hedged with great ramparts right up to the precipice that overhung its western end; and in that space stood the houses and domed tombs of bygone kings and lords, for ever silent between the mountain and the tower.
North amid their noisome pits lay the first of the great heaps and hills of slag and broken rock and blasted earth, the vomit of the maggot-folk of Mordor; but south and now near loomed the great rampart of Cirith Gorgor, and the Black Gate amidmost, and the two Towers of the Teeth tall and dark upon either side.
The Towers of the Teeth swayed, tottered, and fell down; the mighty rampart crumbled; the Black Gate was hurled in ruin; and from far away, now dim, now growing, now mounting to the clouds, there came a drumming rumble, a roar, a long echoing roll of ruinous noise.
There are no more uses of "rampart" in the book.
