Officially called La Iglesia de San Cayetano and a 15-minute trek from the city center, this is one of the best-known colonial churches in Mexico. The mid- to late-18th-century pink-stone facade is brilliantly ornate. Inside are three altars, each hand carved in wood and brightly gilded, in different styles: plateresque, churrigueresque, and baroque. There are also religious paintings from the viceregal period. Both the mine and church are included in any of Guanajuato's
guided tours, and buses (marked "La Valenciana") frequently make the trip from the city center.
