The archbishop Carrillo (1446-1482) elevated the church to the rank of collegiate church. The current building was designed during the time of Cardinal Cisneros (1495-1517) he was awarded the title of "Master" and the current building was designed and constructed between 1497 and 1516 in late Gothic style typical of the age.[4] The tower was built between 1528 and 1582.
It was declared Bien de Interés Cultural in 1904.[5] During the Spanish Civil War (1936-1939), the church was burned. It lost virtually all its treasures in the fire, saving some bars and some chairs from the old choir. In 1991 the diocese of Alcalá restored and elevated to the status of cathedral-master, the Diocese Complutense recovering that which was from the 5th century until 1099.
Exterior
The exterior of the cathedral is simple and austere. The walls are covered by molding type Segovia. They emphasize the cover of the western facade of Flamboyant Gothic style, in which central medallion depicted on Saint Ildefonso; and the tower, designed by Rodrigo Gil de Hontañón[6] and Rodrigo Argüello, in herrerian style, with a height of 62.05 meters. Top is a beautiful spire tower slate.
The cathedral has a severe seventeenth century cloister arches between pilasters. Soils appear covered by Renaissance carpets from nearby convents. In one of the walls the grave of Cardinal Cisneros remains.
Interior
The building's interior is divided into three naves covered by cross vaults resting on pillars fasciculados. The overall shape of the building resembles the traditional Latin cross with marked transept. The entire building suffered much in that fire, and countless works of art and objects of great historical, devotional and sentimental value were lost. Today the cathedral houses apart from its religious functions, an interpretive center and the Cathedral Museum.
