What to see
San Ignacio Miní
These are the best known and most preserved ruins as a result of the restoration work that has been undertaken. The church, the Fathers’ House, the cemetery, some houses and the town council are laid out around the central square.
At night, an image and sound show recreates history and engages visitors in a unique experience.
Santa Ana
It is interesting to see how, with the passing of time, the rainforest has taken over, transformed and eroded the abandoned buildings. Here, the different areas that made up the settlement (referred to as reducción), such as the square, the staircase leading to the school, the orchard and the temple, can be seen. A qualified guide can be hired at the site.
At night, the image and sound show offers a different perspective.
Nuestra Señora de Loreto
It is renowned for having had the first printing press in the region and an important library. What can be seen at present? The remains of the temple where the relics of Antonio Ruiz de Montoya are buried and the ruins of the Virgen de Loreto Chapel. It is an important pilgrimage centre.
Santa María la Mayor
Sitting 120 km away from Posadas, this is the only Jesuit settlement on the west bank of the Uruguay River where architectural ruins still linger. Among the surviving ruins there are walls, chapels, dikes, ditches and trails, as well as workshops, residences and a temporary temple (the original one was destroyed by a fire in 1735).
