This Cathedral is placed in Madrid city centre, in front of the Royal Palace. The temple joins different styles, such as Neoclassic, Neogothic, Neoromanesque. It was consecrated by the Pope John Paul II, during his fourth visit to Spain, the 15th June 1993.

It has a Latin cross plan of 102 meters length by 73 meters high, and joins different styles, the Neoclassic style outside and Neogothic style inside. It has a transept of 66 meters length, 13 chapels, 3 altars and a great dome of 20 meters of diameter. It was built using stone and granite. The main façade is crowned by four statues that were created by the sculptor Ramón Chaparro, and represent four Spanish saints: San Isidro, Santa María de la Cabeza, Santa Teresa de Jesús and San Fernando. They are made of white stone from Colmenar.

It has a double dome which is Gothic inside and Barroque outside. In said dome the twelve apostles are represented. The image of the Virgin of Almudena, the patron saint of the city, has its own altar in the transept of the right nave. It is placed on the central vaulted niche of a spectacular altarpiece, painted by Juan de Borgoña (at the end of the XV Century and beginning of the XVI Century). This altar piece is composed by eighteen boards with scenes of our God´ s life. Kiko Argüello´s Neobizantine paintings were the last elements added to the Cathedral. They are painted in the apse of the cathedral, and represent scenes of Christ´ s life.

In 1944, a National Contest of Architecture is organised in order to solve the difficult problem of finishing the construction of the Almudena. The architects Fernando Chueca and Calos Sidro won it, leaving the Neogothic elements and linking the tempo with its environment through cloisters with columns, chapels and rooms, in this way, the cathedral would be harmonized with the environment of the Royal Palace which is also Neoclassic.
