Fodor's Expert Review Monasterio El Carmen

Still used as a nunnery, this handsome edifice, built in 1725, is regarded as the city's finest example of colonial art. It has five elaborate altars and some fine floral frescos. Next door is a museum, the Pinacoteca Carmelita, with religious works from the 17th and 18th centuries and an interesting exhibition on restoration techniques. Be warned: visiting hours are sporadic.
