This important place of worship—as a cathedral, the most important church not only in the city but in the entire archdiocese—bearing the title "San SALVADOR" was not dedicated to one of the many people we venerate as blessed or saints and ask for their heavenly intercession with God. Rather, it is dedicated to the incarnate Son of God, Jesus Christ, our Redeemer and Savior.

Construction of the current cathedral began in the 14th century on this historically significant square. The magnificent towers that characterize the cathedral were completed by the middle of the 14th century, which is why the cathedral has many Gothic elements.
