The palace on the peak was soon lost to sight again on my climb upward, and the path led direct to the outer donjon of the Moorish stronghold opening upon a narrow path cut along the face of the rock, and bordered on the outer side by a low stone wall. The view down over the steep, rocky slope, with the town of Cintra far below, and the plain limitless beyond, is very fine, and the walls that border the path are clothed with mosses and ferns almost as lovely as those of Bussaco. The fortress must have been impregnable by force; and indeed was only gained at last from the Moors by treason, this very gate having been bought by the Christians from an unfaithful guardian. This narrow path cut on the face of the precipice is the only practicable approach to the fortress, and leads soon to yet another gate flanked by a strong tower built upon one vast, solid boulder. The dells below are filled with billows of verdure; the face of the rock on the inner side of the path is covered with creepers, ferns, and flowers, whilst above them, high up in the dips near the summit, great trees lean over, shading the way by which we come. Yet another strong gate tower we pass through; and with a sudden turn we are inside the fortress, on the right of us a ruined chapel, once a mosque, and on the left a watch-tower, with, at its foot, a monument upon which the cross is graven surmounting the crescent, emblematical of the fate of the adjoining chapel.
To describe in detail this prodigious ruin would be impossible in any reasonable space. The summit of the crag consists of two separate peaks at some distance from each other, the higher one occupied by the main keep, “the royal tower,” and long battlemented walls reach from one point to the other, with bastions at intervals and massive square keeps at the salient angles. On all sides within the great enclosure formed by the battlements, covering the whole summit, remains of towers and buildings of various sorts are scattered, amidst the dense growth of trees and brushwood that have intruded upon the space. The battlements, many of them built upon the rounded boulders that border the precipice and following the contour of the hill top, are strong and perfect still; and it needs but little imagination to people them again with the turbaned and mailed warriors, sheltered snugly behind them, watching for the advancing hosts of the Christian king, certain that, so long as Islam was true to itself, no force could take this stronghold of their race. The view over the battlements on all sides is tremendous. Just below the walls a Titanic scatter of boulders, varying in size from a few feet in diameter to the bulk of a cathedral, and then the descending folds of greenery, with the sunlit plains and clustering towns below; and there on the west, seemingly almost at the foot, a long stretch of breaker-strewn beach, and the blue line of the sea. The view on the Cintra side is almost appalling, the drop from the battlements and boulders to the town being almost sheer, and on the south-east a great bay opens, and the mouth of the Tagus bounds the prospect.
