Built from 1660 to 1774, at the time of the viceroyalty , is the seat of the Catholic Archidiose of Morelia.

It's twin towers have a height of  66m, making it the tallest building in the city. 

Every Saturday night, there is an incredible music / lights / fireworks display well worth going to see.

It begins in total darkness whith awe inspiring gregorian music at about 1000 decibels, and slowly the lights begin illuminating the cathedral, until the entire church is lit. Then the fireworks begin, and what a show.
