The original design came from models created by Claudio de Arcinega and Juan Miguel de Aguero. The bell towers were added 1787-1793 by Jose Damian Ortiz de Castro and the cathedral was completed by Manuel Tolsa in 1813, who added the front facade. The adjacent Church of Sagrario Metropolitano was built 1749-1769.
