This 18th-century Jesuit chapel, acquired by the Frías Silva family of Tucumán after the Jesuits’ expulsion and then expanded in the 1830s, was restored to its original configuration in the 1970s. Note the escape tunnel under the altar. A small collection of funerary urns, Cuzco-school religious art, ecclesiastical vestments and period furniture is displayed.

The chapel is a short walk from downtown. Cross the river bridge and you’ll see it on your left after 750m.
