  The Ruins of San Ignacio Miní, located in the margins of the Paraná river, Misiones province, were declared as cultural heritage by the UNESCO in 1984. In their buildings prevails the rock red sandstone, which is typical from this region. The Mission of San Ignacio Miní should not be considered as a ruin, since the purpose of their preservation deals with the idea of establishing an intertemporal dialog with an extraordinary experience. Indians as well as Jesuits, had a way of life that preserved the identity of the guaraní culture. In this way, biodeterioration studies become very important to the implementation of protection acts and the consequent restoration. The aim of this work was studying the biological colonization of the Ruins and the effect in their biodeterioration. Biofilms samples were analyzed applying microbiological and microscopic techniques (light microscopy and scanning electron microscopy). The chemical study of colonized surfaces was also performed by the surface analytical techniques (EDX). Bacteria, cianobacteria, fungi, protozoa and lichens were Key Words: Bacteria; Biodeterioration; Biofilms; EDX; Protozoa; Ruins of San Ignacio Miní.
