Atotonilco

The Sanctuary of Atotonilco is a church complex and part of a World Heritage Site, designated along with nearby San Miguel de Allende, Guanajuato, Mexico. The complex was built in the 18th century by Father Luis Felipe Neri de Alfaro, who, according to tradition, was called upon by a vision of Jesus with a crown of thorns on his head with blood on his face and carrying a cross. The main feature of the complex is the rich Mexican Baroque mural work that adorns the main nave and chapels. This was chiefly the work of Antonio Martínez de Pocasangre over a period of thirty years. The mural work has led the complex to be dubbed the "Sistine Chapel of Mexico." The complex remains a place of worship and penance to this day, attracting as many as 5,000 visitors every week.
