The plan of Leon is exceedingly fine, surpassed alone among Spanish churches by that of Toledo. Three doorways lead through the magnificent western portal into the nave and side aisles of the Church. These consist of five bays up to the point where the huge arms of the transept spread by the width of an additional bay. In proportion to the foot of the cross, these arms are broader than in any other Spanish cathedral. They are four bays in length, the one under the central lantern being twice the width of the others, thus making the total width of the transepts equal to the distance from the western entrance to their intersection. The choir occupies the fifth and sixth bays of the nave. To the south, the transept is entered by a triple portal very similar in scale and richness to the western. The eastern termination of the church is formed by a choir of three and an ambulatory of five bays running back of the altar and trascoro, and five pentagonal apsidal chapels. The sacristy juts out in the extreme southwestern angle. The northern arm of the huge transepts is separated from the extensive cloisters by a row of chapels or vestibules which to the east also lead to the great Chapel of Santiago. All along its eastern lines the church with its dependencies projects beyond the city walls, one of its massive towers standing as a mighty bulwark of defense in the extreme northeastern angle. [Illustration: CATHEDRAL OF LEON Looking up the nave] It is a plan that must delight not only the architect, but any casual observer, in its almost perfect symmetry and in the relationship of its various parts to each other. It belonged to the primitive period of French Gothic, though carried out in later days when its vigor was waning. It has not been cramped nor distorted by initial limitation of space or conditions, nor injured by later deviations from the original conception. It is worthy of the great masters who planned once for all the loveliest and most expressive house for the worship of God. Erected on the plains of Leon, it was conceived in the inspired provinces of Champagne and the Isle de France. It has a total length of some 308 feet and a width of nave and aisles of 83. The height to the centre of nave groining is 100 feet. The western front has two towers, which, curiously enough, as in Wells Cathedral, flank the side aisles, thus necessitating in elevation a union with the upper portions of the façade by means of flying buttresses.
