The fourth mission in the World Heritage Site, the mission of Concepción, was initially founded in 1699 by the Jesuit priests Fr. Francisco Lucas Caballero and Fr. Francisco Hervás. A nearby mission, San Ignacio de Boococas, was incorporated in 1708. The mission was moved three times: in 1707, 1708 and 1722. The mission was inhabited by the Chiquitanos, the largest tribe in the region. The mission church was constructed between 1752 and 1756, by Fr. Martin Schmid and Fr. Johann Messner. From 1975 to 1996 the mission was reconstructed as part of Hans Roth's restoration project. © iStock-jarcosa
