Pucara de La Compañia, promaucae fortress, later used by Incas, located in La Compañia Mount, commune of Graneros, Chile. It is notable as the most southerly building that remains of the Inca Empire. It was declared a National Monument of Chile.
There can be identified three moments of historical occupation of the pucará:
The vestiges of the pucará consist of the bases of 7 structures of circular plant , a major construction and other attached buildings that can be sites(places) of alertness. The flat summit of the hill is surrounded, in addition, with defensive perimeter walls .
Cerro La Compañia was declared Chile National Monument for the Decree n º 1191 , March 11, 1992. In spite of it, these remains have neither a tourist suitable access, nor a control and care on the part of the authorities. An attitude that denotes little respect for the archaeological patrimony of the pucará is the existence of the great antenna of cellular telephony in one of the points of the summit of the Mount. The works of installation of this structure, realized in 1997, included a way and movements of land, which destroyed four meters of a defensive wall.
