We have, during the Latin American spring, studied the material traces of state oppression and social movements in Temuco, Chile, and the transformation of the urban landscape with archaeological surveys. Our results demonstrate alterations in the urban landscape related to both police presence and protesters. Large amounts of teargas-projectiles and rubber bullets indicate strong police presence and repression of different social movements. We have also identified protection and resistance modes in the form of shields, paint bombs, and protective masks, often associated with graffiti's, barricades, and other alterations of the public space. Material vestiges combined with interviews have shown how state institutions have tried to cover up the traces of violence. We argue that archaeology can play a central role in this process and in recording the materiality of these events with the aim to hand over the information to human right associations to prevent state oppression.
