This mission was built by the Jesuits in 1633.
The mission was designed and maintained by the Jesuits. I once served as a center of protection as well as the development for the Guarani people who were in constant danger from the menacing Portuguese bandeiras and slave traders.
The mission was active and thrived until the late 1750s, when the Guarani war, during which time the buildings were severely damaged by fire, and the subsequent expulsion of the Jesuit Order from Argentina, resulted in the place being abandoned.
Regrettably, it was not until the 1940s that the ruins were unearthed and eventually designated as a world historic site. Today, visitors can see what remains of the ruins, which is sadly not much. The original foundations of the cathedral can still be seen, and one can only assume that the church was originally a magnificent construction. The walls, or what’s left of them, are as thick as two meters. The red sandstone used to construct everything comes from the local area. Some of the original sculptures on the main gateways may still be seen today, which is fortunate.
