The Pucará de Tilcara is a pre-Inca fortification or pukara located on a hill just outside (approximately a 15-minute walk) the small town of Tilcara, in the Argentine province of Jujuy. The location was strategically chosen to be easily defensible and to provide good views over a long stretch of the Quebrada de Humahuaca.
This ancient town was occupied between the end of the 8th century AD. and the moment of Hispanic - indigenous contact (16th century AD), presents a great concentration of archaeological structures distributed over more than 8 hectares of surface. These structures, of which only the walls and foundations are mainly visible, are part of the old houses, workshops, squares, tombs and ceremonial spaces, which the ancient inhabitants of Quebrada de Humahuca inhabited.
