An unfinished dream of the Jesuit missionsThe mission of Jesús de Tavarangüé is one of the surviving Guaraní-Jesuit reductions — the settlements founded by Jesuit missionaries across South America in the 17th century. It lies in the department of Itapúa in southern Paraguay, about 38 kilometres from the city of Encarnación. FoundationThe mission was founded in 1685 by the Jesuit father Jerónimo Delfín. The settlement had to move several times before reaching its final site, where the community built one of the largest mission churches of its era. A church frozen in timeThe great church was never completed: work stopped abruptly when King Charles III of Spain expelled the Jesuits from his empire in 1767. What remains is unusual and striking — the design, attributed to the Spanish architect Antonio Forcada, features trilobed (three-lobed) arches that recall the Moorish architecture then present in Spain, a form rare among the missions. The ruins convey the singular way of life and education that the reductions embodied. World HeritageRediscovered long after the missions were abandoned, Jesús de Tavarangüé was inscribed on the UNESCO World Heritage List in 1993, together with the nearby mission of La Santísima Trinidad del Paraná.
