Puerto Iguaz is a frontier city in the province of Misiones, Argentina. With a population of 82.227 (2010 census [INDEC]), it is the fifth largest city in the Province, after Posadas, Ober, Eldorado and San Vicente. The world-renowned Iguazu Falls are only 18 kilometres (11 mi) away from the city, and as a result the city has developed its infrastructure around tourism. In 1542, Spanish explorer lvar Nez Cabeza de Vaca was the first European to discover what is now called Iguazu Falls. He was drawn by the noise of the water, which can be heard at a distance of several kilometers. When the Spanish arrived in the 16th century, the Guaran Indians were the principal inhabitants of the area. Despite its early exploration, the area remained occupied only by the Guaran until 1880. In 1881, the province of Corrientes, which at that time included what is now Misiones, sold 50 square leagues (13,000 square kilometres (5,000 sq mi)) at the current site of Puerto Iguaz near the falls.
