The condition of Episcopal see, concede by the pope Clement III, in 1189, will determine, in a great measurement, the history and the landscape of our city, equipping with the environment intra walls of a special elegance.

The temple of the cathedral, present at the sight before entering the city, chairs with large a majesty the old helmet, while being used as invitation with all that which wishes to go for one previous time.

The constructive process developed throughout the centuries, made it possible to combine, in only one building, two perfectly differentiated cathedrals:

What is old, of Romance style, is work, inter alia, Juan frances, and it is carried out during centuries XIII and XIV.

In it the hood of San Pablo, old Capitulary room underlines, whose access shows a central door and two windows in what is side. Equipped with a transition style Romance Gothic combined with certain contributions from Eastern nature (Byzantine). The hood is of square plant, with Byzantine octagonal cupola, which in the manner external a covered pyramid of grudges, similar to the tower of the "Cock" of the cathedral of Salamanca, known as the tower of "Melon". Complete the tower a ball gallonada in its higher part.

The frontage of the Feet presents a central body with vain of a half - not crowned by a hornacina which represents the Annunciation of the Virgin, above it underlines a rivet washer of big size. In the cloister, bond of union of the two cathedrals, underline the Romance columns and capital, as well as the arcs and the safe deposits of crucería. When we visit this place, we did not forget to raise the sight through those arcades, towards the Tower of Melon.

At the end of century XV one projects a new cathedral. This ambitious company, that pretended to completely replace the old cathedral, it stumbles with multiple difficulties, which, in 1760, justifies the end of works. The new cathedral lays out three ships equal height, while following the model of Renaissance temple. Their slender pillars leave the nerves which finish in broken safe deposits of great complexity. The great space unit provides to the visitor a splendid spectacle, where underline the larger challengeable, one of the most remarkable elements of the Spaniard baroque. The plan is in Alonso de Balbás, the sculptures are due to Gregorio Fernández and of the four fabrics, two were painted by Francisco Ricci (century XVI) and what is remaining, of less quality, belong Luis Fernández and Mateo Gallardo. That gilded of the sculptures is in Simón López.

Of special mention by its great beauty is the Gate of the Sacristy (1498 - 1506), of style Plateresc, was carried out by Juan d' Alava with the special collaboration of Francisco de Colonies.

With the larger challengeable one finds the Tomb of the Bishop Ponce de Leon. It is carried out of marble and represents with side in speech, of Renaissance style it was carried out by Mateo Sanchez de Villaviciosa.

The body is leaned in the interior part of the southernmost gate. In a city it rocks goods organists and of great musical tradition, could not miss an instrument like this one. It acts of a philosopher's stone of style Plateresc, with beautiful sculptures and relieves.

The splendid grid Plateresc which gives access to the Chorus was carried out by the Galician goldsmith Juan Bautista Celma.

The New Cathedral preserves the seats which carried out outside, at the end of century XV by German Rodrigo for the Old Cathedral. Sculptural work carried out of wood of drowning, with vast and rich person of iconography (religious subjects, fabulists, moralizing, including some obscene). Of Gothic style blazing, with openings of a great beauty, like their watershed and conclusions. In the higher part, the higher armchairs have inlays, remarkable it central are devoted to the bishop and both of the ends which represent with Kings Catholics.

Its outside, of a great richness of ornament, presents a splendid whole of watershed, pináculos, picture windows, images and medallions.

Of large monumentality are the frontages which correspond with the ends of cruising. The northern or principal frontage was built in century XVI, while following Renaissance models. The central part will structure in four modules, all separated by a traditional entailment. In the lower part one finds the door of access to the temple. They took share work in addition to Juan Alava, Alonso de Covarrubias, and Diego de Siloé and of Rodrigo Gil de Hontañón. The frontage is decorated with decoration Plateresc abundant and admirable.

The southernmost or so called frontage of Enlosado (1538 and 1548) was projected by Diego de Siloé. Its design is more modern, with triumphal arch of a half - not, and at its side’s Ionian peer’s columns. The higher body with a double arcade which a window shelters. In top, at the two sides of picture window, one finds the escudos of the emperor and of side gift Gutiérrez de Carvajal.
