This Jesuit church with a 1767 Churrigueresque facade is also called Espíritu Santo. Beneath the altar is a tomb said to be that of a 17th-century Asian princess, who was sold into slavery in Mexico and later freed. She was supposedly responsible for the colorful china poblana costume – a shawl, frilled blouse, embroidered skirt, and gold and silver adornments. This costume became a kind of ‘peasant chic’ in the 19th century. But china ( chee -nah) also meant ‘maidservant, ’ and the style may have evolved from Spanish peasant costumes.
