Jujuy is a province of Argentina, located in the extreme northwest of the country, at the borders with Chile and Bolivia. The only neighboring Argentine province is Salta to the east and south. Pre-Columbian inhabitants known as the Omaguacas and Ocloyas, who were later conquered by the Incas during their expansion period, practiced agriculture and domesticated the guanaco. They had huts made of mud, and erected stone fortresses to protect their villages. An example of such fortresses is Pucará de Tilcara, Pucará meaning "fortress" (word also used for the Argentine combat aircraft Pucara).
