Never was a church more altered for the worse after its first erection than was this. It is now a vast congeries of chapels and excrescences of every shape and every style, which have grown round it at various dates, and, to a great extent, concealed the whole of the original plan and structure; and of these, the only valuable Mediæval portions are the cloisters and sacristies, which are, indeed, but little later in date than the church, and two of the chapels on the north side of the chevet, one of which is original, and the other at any rate not much altered. The rest of the additions are all either of the latest Gothic, or of Renaissance. The principal entrances to this church of “Santa Maria la Mayor” are at the west end and in the north and south transepts--the two last original, the former a modern alteration of the old fabric, made only a few years ago, and of the meanest kind. The Archbishop’s palace occupies the space on the south side of the nave; and the ground on which the whole group of buildings stands, slopes so rapidly from the south up to the north, that on the south side a steep and picturesque flight of steps leads up to the door, whilst on the north, on the contrary, the door is some fifteen feet above the floor, and has to be reached by an elaborate flight of winding steps from the transept. Owing to the rapid rise of the ground, and to the way in which the church is surrounded by houses, or by its own dependent buildings, it is very difficult to obtain any good near views of it, with the exception of that of the west end from the Plaza in front of it; but the views from the Prado, from the opposite side of the river, and from the distant hills and country, are all very fine; and it must be allowed that in them the picturesque richness of the later additions to the fabric produces a very great effect. Having thus given some general idea of the plan of the church, I will now describe its parts more in detail. [Illustration: Compartment of Nave.]
