The former convent now houses the Museo Virreinal de Guadalupe, with the building's original religious paintings by Miguel Cabrera, Juan Correa, Antonio Torres and Cristóbal Villalpando. Wandering through the building is a delight; note the extraordinary perspective of the paintings in the cloisters from where you stand. Visitors can see part of the library and its 9000 original volumes (the oldest dates to 1529 and thousands are in storage), and step into the stunning choir on the church's upper floor, with its fine carved and painted chairs.
