The Alcazar is the only important building seen in entering on this side; but from the other side of the city where the bridge of San Martin crosses the Tagus, the cathedral is a feature in the view, though it never seems to be so prominent as might be expected with a church of its grand scale. From both these points of view, indeed, it must be remembered that the effect is not produced by the beauty or grandeur of any one building; it is the desolate sublimity of the dark rocks that bound the river; the serried phalanx of wall, and town, and house, that line the cliffs; the tropical colour of sky, and earth, and masonry; and, finally, the forlorn decaying and deserted aspect of the whole, that makes the views so impressive and so unusual. Looking away from the city walls towards the north, the view is much more _riant_, for there the Tagus, escaping from its rocky defile, meanders across a fertile _vega_, and long lines of trees, with here a ruined castle, and there the apse of the curious church of the Cristo de la Vega, and there again the famous factory of arms, give colour and incident to a view which would anywhere be thought beautiful, but is doubly grateful by comparison with the sad dignity of the forlorn old city. The buildings to be studied here are of singular interest, inasmuch as they reflect in a great degree the striking history of the city itself, as well as of the kingdom of which it was so long the capital. There is no doubt that there was a cathedral, as well as some churches,[205] here before the conquest of this part of Spain, in A.D. 711, by the Moors; and in the course of the long period of nearly four centuries during which the Mahomedan rule lasted, many buildings were erected, and a Moorish population was firmly planted, which, when Alonso VI. regained the city in 1085, was still protected, and continued to live in it as before. The Moors had, indeed, set an example of toleration[206] worthy of imitation by their Christian conquerors; for though it is true that they converted the old cathedral into their principal mosque, they still allowed the Christians to celebrate their services in some other churches[207] which existed at the time of the Conquest; and during the greater part of the Christian rule, their tolerant example was so far followed, that the Moors seem to have enjoyed the same freedom, and to have lived there unmolested, whilst they built everywhere, and acted, in fact, as architects, in the old city, not only for themselves, but also for the Christians and the Jews, down to the establishment of the Inquisition. It is a very remarkable fact, indeed, that with one grand exception nearly all the buildings of the twelfth, thirteenth, and fourteenth centuries, which are to be seen here, are more or less Moorish in their character;[208] and though the cathedral, which is the one exception, is an example of thoroughly pure Gothic work almost from
