Strange to say, there are no doors leading, as they logically should, into the centre of the arms of the transept. Through some perversity, altars have taken their place, while the northern and southern entrances have been pushed westward, opening into the first bays of the side aisles. The southern door leads to a vestibule, the sacristy with fine Gothic vaulting disfigured by later painting, a fine fifteenth-centurychapel and the cloisters. None of this can be seen from the front, as it is hidden by adjoining houses and a bare, pilastered wall crowned by a carved Renaissance balustrade. The galleries of the present cloisters are later Gothic work with Plateresque decorations and arches walled up. Avila Cathedral is, as it were, a part and parcel of the history of Castile during the reigns of her early kings, the turbulent times when self-preservation was the only thought, any union of provinces far in the future, and a Spanish kingdom undreamed of. She was a great church in a small kingdom, in the empire she became insignificant. Much of her history is unknown, but in the days of her power, she was certainly associated with all great events in old Castile. Her influence grew with her emoluments and the ever-increasing body of ecclesiastical functionaries. In times of war, she became a fortress, and her bishop was no longer master of his house. The Captain-General took command of the bastions, as of those of the Alcazar, and soldiers took the place of priests in the galleries. She was the key to the city, and on her flat roofs the opposing armies closed in the final struggle for victory. The Cathedral has, in fact, only an eastern and a northern elevation, the exterior to the west and south being hidden by the huge tower and the confused mass of chapels and choir which extend to the walls and houses. The western entrance front is noble and dignified in its austere severity; probably as old as the clerestory of the nave, it is a grim sentinel from the first part of the fourteenth century. With the exception of the entrance, it speaks the Romanesque language, although its windows and some of its decoration are pointed. It is magnificent and impressive, very Spanish, and almost unique in the Peninsula. Four mighty buttresses subdivide the composition; between these is the entrance, and to the north and south are the towers which terminate the aisles.
