The Citadel of Burgos, at present an insignificant fortress, was formerly a place of considerable importance, and commanded the surrounding country; especially on the side on which the town--placed at the foot of the eminence--lay beneath its immediate protection, and could listen unscathed to the whizzing of the deadly missiles of war as they passed over its roofs. During the various wars of which Castile has been the theatre at different periods, this citadel has, from its important position, occupied the main attention of contending armies; and, from forming a constant _point-de-mire_ to attacking troops, has finally been almost annihilated. The principal portion of the present buildings is of a modern date, but, although garrisoned, the fortress cannot be said to be restored. The extent of the town was greater than at present, and included a portion of the declivity which exists between the present houses and the walls of the fortress. At the two extremities of the town-side of the hill, immediately above the level of the highest-placed houses now existing, two Arab gate-ways give access through the ancient town-walls, which ascended the hill from the bottom. Between these there exists a sort of flat natural terrace, above the town, and running along its whole length, on to which some of the streets open. On this narrow level stood formerly a part, probably the best part, of the city, which has shared the fate of its protecting fortress; but, not being rebuilt, it is now an empty space,--or would be so, but for the recent erection of a cemetery, placed at about half the distance between the two extremities. Before, however, the lapse of years had worn away the last surviving recollections of these localities, some worshipper of by-gone glory succeeded in discovering, on the now grass-grown space, the situations once occupied by the respective abodes of the Cid and of Fernan Gonzalez. On these spots monuments have been erected. That of Gonzalez is a handsome arch, the piers supporting which are each faced with two pillars of the Doric order on either side; above the cornice there is a balustrade, over which four small obelisks correspond with the respective pillars. The arch is surmounted by a sort of pedestal, on which is carved an inscription, stating the object of the monument. There is nothing on the top of the pedestal, which appears to have been intended for the reception of a statue. The monument in memory of the Cid is more simple. It consists of three small pyramids in a row, supported on low bases or pedestals; that in the centre higher than the other two, but not exceeding (inclusive of the base) twenty feet from the ground. On the lower part of the centre stone is carved an appropriate inscription, abounding in ellipsis, after the manner usually adopted in Spain.
