The Great Water: How Misiones Became a Crossroads of Nature and Colonial History

In short: Tucked into Argentina's northeastern corner, Misiones is defined by the thunderous Iguaçu Falls and a complex past. Once a hub for Jesuit missions, this isolated province evolved through territorial disputes and waves of European immigration to become a unique ecological and cultural landscape where orchids grow alongside towering pine forests.

Misiones is an isolated province in northeastern Argentina, bordered by the Alto Paraná, Iguazú, and Uruguay rivers. Its geography is dominated by the Paraná Plateau, which creates the dramatic setting for the Iguaçu Falls. These falls, whose name derives from a Guaraní word for “great water,” consist of approximately 275 separate cataracts. Stretching 1.7 miles, the falls are nearly three times wider than Niagara Falls, with a mean annual flow of about 62,000 cubic feet per second.

The region’s history is deeply tied to the 17th-century Jesuit missions that established a network of villages to teach the local Guaraní population western agriculture and crafts. Following the suppression of the Jesuit Order in the late 18th century, the area faced economic decline and shifting political control. By the late 19th and early 20th centuries, the province began to transform through the Immigration and Colonization Law, which encouraged European settlers to populate the territory. This influx of immigrants, including Poles and Ukrainians, helped shape the modern agricultural landscape, characterized by plantations of citrus and yerba mate.

Ecologically, Misiones is a site of intense botanical and zoological variety. The region’s vegetation ranges from semi-deciduous to tropical, featuring rare water plants like the Podostemaceae that cling to the rocky ledges of the falls. The wildlife is equally diverse, housing jaguars, ocelots, tapirs, and a wide array of birdlife such as toucans. Today, the area is protected by national parks in both Argentina and Brazil, with the Argentine park designated as a UNESCO World Heritage site in 1984, ensuring the preservation of this unique intersection of biodiversity and history.
