Yapeyú (5,000 residents, on the Uruguay River, border with Brazil) is one of the most meaningful towns in Argentine history — the birthplace of General José Francisco de San Martín, liberator of Argentina, Chile and Peru, born there on February 25, 1778, son of Lieutenant Governor Juan de San Martín and Gregoria Matorras. The family left Yapeyú in 1781 when José was 3 years old, but the place is etched in his biography and is now a mandatory destination of Argentine patriotic pilgrimage, especially every August 17 (anniversary of his death in Boulogne-sur-Mer, France, in 1850) and February 25 (birthday). Before the Liberator's birth, Yapeyú was one of the 30 Jesuit-Guaraní reductions founded by the Society of Jesus — established in 1626 and grown into one of the system's most prosperous, with 8,000 Guaraní inhabitants at its peak, a printing press, violin and religious carving workshops, extensive ranching and a 4,000-volume library. After the Jesuit expulsion by order of Charles III in 1767-1768, the reductions declined. Of Yapeyú remain the foundations of the original church, now rebuilt on the colonial plan. The whole town was declared a National Historic Site in 1937. Central attractions: San Martín Birth House (museum, free entry, daily 8-18, faithful replica of the original colonial house with period furniture, replica curved saber and documents), Iglesia Nuestra Señora de los Reyes (rebuilt on Jesuit foundations), historic vault holding remains of the Liberator's sisters, Plaza Sanmartiniana (with monument), Sanmartiniano Museum (documentary archive), "Padres de la Patria" Visitors Center. Combinable with Corrientes capital (400 km), Mercedes/Iberá (165 km), Paso de los Libres (Brazil border, 80 km) and the Misiones Jesuit Route (San Ignacio Miní, 220 km).
