As this northern façade is almost fifteen feet higher than the ground-plan of the temple,—on account of the street being much higher,—a flight of steps leads down into the transept. As a Renaissance work, this golden staircase is one of Spain's marvels, but it looks rather out of place in an essentially Gothic cathedral.

To avoid the danger of falling down these stairs and with a view to their preservation, the transept was pierced by another door in the sixteenth century, on a level with the floor of the building, and leading into a street lower than the previous one; it is situated on the east of the prolonged transept,[{183}] or better still, of the prolonged northern transept arm.

On the south side a cloister door corresponds to this last-named portal. Though the latter is plateresque, cold and severe, the former is the richest of all the portals as regards sculptural details; the carving of the panels is also of the finest workmanship. Beside it, the southern front of the cathedral coincides perfectly with the northern; like the Puerta de la Plateria in Santiago, it is rendered somewhat insignificant by the cloister to the right and by the archbishop's palace to the left, between which it is reached by a paved series of terraces, for on this side the street is lower than the floor of the cathedral. The impression produced by this alley is grand and imposing, unique in Spain.

Neither is the situation of the temple exactly east and west, a rare circumstance in such a highly Catholic country like Spain. It is Roman cruciform in shape; the central nave contains both choir and high altar; the aisles are prolonged behind the latter in an ambulatory.

The lateral walls of the church, enlarged here and there to make room for chapels[{184}] of different dimensions, give an irregular outline to the building which has been partly remedied by the free use of buttresses, flying buttresses, and pinnacles.

The first impression produced on the visitor standing in either of the aisles is that of size rather than beauty; a close examination, however, of the wealth of statues and tombs, and of the sculptural excellence of stone decoration, will draw from the tourist many an exclamation of wonder and delight. Further, the distribution of light is such as to render the interior of the temple gay rather than sombre; it is a pity, nevertheless, that the stained glasses of the sixteenth century see were all destroyed by a powder explosion in 1813, when the French soldiers demolished the castle.

The unusual height of the choir mars the ensemble of the interior; the stalls are lavishly carved, but do not inspire the same feeling of wonderful beauty as do those of Leon and Toledo, for instance; the reja or grille which separates the choir from the transept is one of the finest pieces of work in the cathedral, and, though massive, it is simple and elegant.

The retablo of the high altar, richly gilt,[{185}] is of the Renaissance period; the statues and groups which fill the niches are marvellously drawn and full of life. In the ambulatory, imbedded in the wall of the trascoro, there are six plaques in low relief; as sculptural work in stone they are unrivalled in the cathedral, and were carved, beyond a doubt, by the hand of a master. The croisée and the Chapel of the Condestable are the two chief attractions of the cathedral church.

The last named chapel is an octagonal addition to the apse. Its walls from the exterior are seen to be richly sculptured and surmounted by a lantern, or windowed dome, surrounded by high pinnacles and spires placed on the angles of the polygon base. The croisée is similar in structure, but, due to its greater height, appears even more slender and aerial. The towers with their flèches, together with these original octagonal lanterns with their pinnacles, lend an undescribable grace, elegance, and majesty to what would otherwise have been a rather unwieldy edifice.

The Chapel of the Condestable is separated from the ambulatory (in the interior of the temple) by a good grille of the sixteenth[{186}] century, and by a profusely sculptured door. The windows above the altar are the only ones that retain painted panes of the sixteenth century. Among the other objects contained in this chapel—which is really a connoisseur's collection of art objects of the fifteenth and sixteenth centuries—can be mentioned the two marvellously carved tombs of the Condestable and of his wife.
