Traces of human habitation here go back more than 10,000 years. Spanish and Portuguese conquistadores displaced the earlier inhabitants in the 16th century. The name of the park and the river means 'large water' in Guaraní. A 1970 law made the Iguazú National Reserve the western part of the park. Victoria Aguirre paid for the track that led from the town to the falls.
