Commenced at the end of the eleventh century by Alva Garcia, a native of Navarre, this early Gothic building is still unfinished. Not much is, however, of this early date, for the general style of the building is of the end of the next century, and many alterations have followed this in later years.

The west front has but one tower, the north—the other, the south, does not rise above the roof. The favourite ball decoration of late Gothic Spain is in evidence, and guarding the doorway are a couple of uncouth mace-bearers. Very terrible are these hairy granite men, but not so dangerous looking as the two lions which stand on pedestals and are chained to the Cathedral walls. Always on guard, these four strange figures have no doubt many a time struck a holy terror into the hearts of would-be evil-doers as they entered the church, and I daresay kept the thoughts of others in the straight line.

The north door is early pointed and carries figures in each jamb, the tympanum is decorated with reliefs of the Betrayal and Last Supper, but all the figures are sadly mutilated.

The third entrance is at the south-east corner of the Cathedral, and is a later addition, opening outside the walls of the city on to the Calle de S. Segundo.

The interior of the Cathedral is very simple and massive, partaking more of strength than elegance. It is a fitting inside to the severity of the fortress-like exterior. The nave is narrow and lofty, and so are the aisles. The large clerestory windows have their tracery above blocked up, and the lower lights have been treated in the same way, thus giving a certain resemblance to a triforium, a feature the church does not possess.

The aisles in the apse are double, like those at Tortosa, and although the single columns in the centre are very beautiful, these aisles have not the elegance of those in the other Cathedral. The apse is very dark, the stone work at one time was painted red and the little that remains of this colour adds to the religious gloom of its double aisles.

The columns throughout the Cathedral were built to bear great weight, their capitals are simple and their bases the same. The little light that glimmers through the windows adds greatly to the sombre strength of this fine building, which, more than any other of its size, reflects the life of the Spain of those days in which it was erected. Street thinks it less influenced by outside art than any other building in the country, and instances the unique method of laying the stone of the root as supporting this opinion.

The transepts contain some good glass, as also do the windows in the chancel. There are many good early tombs throughout the Cathedral. Judging from their style Avila was left alone when Chirriguera was erecting monstrosities elsewhere, and to me it is the most homogeneous of Spain's Cathedrals. The retablo over the High Altar rises in three stages and contains pictures by Berruguete, Santos Cruz and Juan de Borgoña. On this account my last remark might be criticised, for the whole piece is a jumble of styles. The chancel is, however, too narrow for a view of this medley from the body of the church, and wherever one roams in the building nothing attracts the eye or disturbs the mind by being too flagrantly incongruous.
