Un cusco en el Mapocho. Stories from the Tahuantinsuyu: An immigrant lost in Santiago's subway discovers that the city he inhabits conceals a buried secret: Santiago was founded over a cusco, an administrative center of the Tahuantinsuyo Empire. Through his wandering across the city and the testimony of pre-Columbian history researchers, the film reconstructs the Inca presence in the Mapocho Valley and proposes a decolonial reading of Chilean urban territory.
