Pukara (Aymara and Quechua for "fortress", hispanicized spellings pucara, pucará) is a ruin of the fortifications made by the natives of the central Andean cultures (that is to say: from Ecuador to the Central Valley of Chile and the Argentine Northwest) and particularly to those of the Inca.
The provinces of Jujuy and Salta (in the north-west), and Misiones (in the north-eastern Mesopotamia), are the leading ones, with over 45,000 tonnes/year each.
