This church faces the Plaza de Armas. It is often imaginatively illuminated in the evenings, especially on weekends.San Francisco's belfries were finished in the 20th century – too late for the Spanish Crown to collect its tax. Inside are elaborate stone carvings and decadent altars, and at the entrance is an interesting collection of dangling silver sacred hearts. Visit the church’s small Museo de Arte Religioso (Religious Art Museum) to see 17th-century religious paintings done by indigenous artists and the creepy catacombs, where many monks lie buried. The intricately sculpted Capilla de la Dolorosa to the right of the nave is considered one of the finest chapels in the city.
