The building was designed by Spanish architect Jose Rafael Moneo and built to last 500 years. It was opened to the public in 2002. Moneo combined traditional European motifs into a modern and new structure.
It caused quite a few controversies due to its interesting design, the high costs required to complete the building, and the Archbishop's decision to store over 1,200 corpses on shelves in the church basement.
Inside the cathedral is a natural light that enters through the large windows and above the altar is a bright and impressive cross. If you go down to the Crypt Museum, you can see the city's previous cathedral, built in 1876 and damaged by an earthquake in 1994.
The large bronze doors at the front of the building were created by the sculptor Robert Graham, who also sculpted the statue of Our Lady with the angels guarding it from above.
