This work examines the way in which alternative memory sites are built. I will focus in a ruin’s cartography in order to speak about the disappeared places of manifestation of the counterculture movement’s for Chilean youth during Pinochet’s dictatorship (1973-1989). Although this memories and narratives don’t necessary deal directly with trauma, they work with the violence and repression as well as with that the lack of places to freely express meant for them. The way in which these groups of young people express in a city under constant vigilance and curfew it is examined in this article. Throughout the analysis of three audiovisual pieces, two documentaries films and one video art, the countermovement of punk appears as a way to occupy Santiago during military dictatorship in the late eighties. Therefore, it can be seen how a ruin’s cartography has been built once this past is revisited from their present’s perspective. The memories seen in these audiovisual works show not only the underrepresented underground movement. But also connects their particular history with Chile’s collective memory of the latest years of dictatorship
