Its construction was completed in 1745 as a temple and auditorium of the Royal and Pontifical University of Santiago de la Paz and served this purpose from 1745-1767. It also served as a royal chapel and conciliar seminary of San Fernando. This is a sanctified place. There are guards that stand tall watching over all day long, surrounded by flags...
The exterior of this church is quite impressive from the outside - which is all I've seen after many attempts to see the inside. The small courtyard outside affords visitors a hint at what might be inside. There are some small doors that one can peek through but you can barely just glimpse the altar.
This is an often over looked church as it is dwarfed by everything surrounding it. Not the same caliber as a cathedral but this church has significant historical value and is worth seeing.
The church bells came from a monastery in San Francisco.
