Brief synthesisJesuit Missions of La Santísima Trinidad de Paraná and Jesús de Tavarangue are part of a series of 30 missions in the Río de la Plata basin established by the Society of Jesus (the Jesuits) during the 17th and 18th centuries. Criterion (iv) : La Santísima Trinidad de Paraná and Jesús de Tavarangue are exceptional examples of the Jesuit missions built in the 17th and 18th centuries throughout this region. This is especially apparent with the rapid development of the neighbourhood surrounding La Santísima Trinidad where a screening of trees has been suggested. A management plan for La Santísima Trinidad de Paraná was completed in October 2011 and the management plan for the Mission of Jesus is under development. Various restoration projects undertaken at La Santísima Trinidad since 1980 have focused on repairing damaged buildings.
