This is the most impressive sight in Paraguay and also pretty much the only organised tourist attraction in the whole country. It is the first UNESCO World Heritage site (declared in 1993) I have visited that is virtually deserted of people. The whole area is just yours to stroll around. The ruins are from the 17th century when Jesuit missionaries from Spain arrived in Paraguay and “brought civilisation” to the native Guarani population. The ruins consists of the main church, Jesuit quarters and houses of local Guarani people. So many decorations are well preserved. We read that they are perfect example of Mestizo art, i.e., a mixture of European and South American art.
