Named after the patron saint of miners. Above the altar of this 18th-century chapel is an image of the Virgin said to be capable of healing the sick. Thousands of pilgrims flock here each year on September 8, when the image is carried to the cathedral. Facing the chapel stand three imposing equestrian statues of the victors of the battle of Zacatecas - Villa, Ángeles and Pánfilo Natera.
