Jesuit Missions of La Santísima Trinidad de Paraná and Jesús de Tavarangue is the only world heritage site in Paraguay. It was inscribed in 1993, as the testimony of the Jesuits' Christianization of the Río de la Plata basin in the 17th and 18th centuries. The site represents a fusion of cultures in which the process of Christianisation permitted the indigenous population to retain elements of their traditional culture.
