A baroque structure on the outside dating from 1708 to 1716, this hushed sanctuary to Mexico's patron is a different story within. Get ready for a glistening profusion of pink, red and gold, gold, gold! The interior decorations date from 1915. Springing out of all this elaboration is a series of large paintings depicting the conversion of the indigenous peoples to Christianity. They show scenes such as sacrificial victims about to be executed before being saved by the god-fearing folk of Spain.
Beside the church, the much less splashy Ex-Convento de San Diego was built in 1761 as a monastery and now houses the Faculty of Law and Social Sciences of the Universidad Michoacana de San Nicolás de Hidalgo.
