I visited some 20 Jesuit mission sites in Paraguay, Argentina, and Brazil, including San Ignacio, Loreto, Santa Ana, and Sta Maria la Mayor. There are other mission sites in the region that need protection and the support that inclusion on the UNESCO World Heritage Sites lists confer. At the top of the list I would include several mission sites in Brazil, particularly San Lorenzo Martir, and San Cosme in Paraguay. Other sites, such as Corpus Christi and Martires, need protection and rehabilitation.
