San Ignacio: Argentina’s UNESCO WORLD HERITAGE

San Ignacio Miní, a Jesuit reduction founded in the early seventeenth century, played a pivotal role in evangelizing the Guaraní natives.

Who built San Ignacio Mini?

San Ignacio Mini’s construction dates back to around the year 1610. The Jesuit missionaries established the mission to escape attacks and invasions by bandeirantes and mamelukes, who besieged Jesuit reductions with the intent to capture natives and sell them as slaves. The Peruvian Jesuit priest, missionary, and writer Antonio Ruiz de Montoya arrived with 12,000 aborigines, re-founding Loreto and San Ignacio Miní, also known as San Ignacio de Ipaembucú.

The San Ignacio Miní settlement endured for 150 years until the Society of Jesus was expelled from the Spanish colonies. The aborigines struggled to maintain the Jesuit-designed structure, leading to a rapid demographic decline.

In 1817, the San Ignacio reduction suffered looting and burning, along with other reductions, by Paraguayan troops during the prevailing anarchy in the country.

The Misiones territory was annexed to Corrientes province in the following years, as part of Argentina. The region remained practically uninhabited until 1870 when non-indigenous contingents returned, occupying the area bordering the Paraná River and the Yabebirí stream. This coincided with the end of the War of the Triple Alliance and the definitive separation of Misiones from Corrientes province.

Recent history commenced with the measurement carried out by National Surveyor Don Juan Queirel, who delineated the urban center of San Ignacio by order of the Corrientes provincial authorities on September 25, 1877. The new town was officially founded on January 18, 1907, with the arrival of the first settlers. Among them were nMarcelino Boix, Pablo Allain, Joaquín Alcaraz, Pablo Martín, Adolfo Lanusse, and the Palacios brothers.

The Missions of San Ignacio Miní boast an Interpretation Center providing insights into the daily lives of the Guaraní aboriginal group until the Jesuits’ arrival, alongside an account of the conquerors’ arrival and the resulting cultural symbiosis. The tour concludes with a scale model of the mission, depicting San Ignacio Miní at the peak of its history.
