This article compares the way in which the tensions and confrontations between Argentina and Chile are remembered by going through the memories of violence in a marginal and frontier region, in the valleys of the Cochamó, Manso and Puelo rivers, included between Chile and Argentina. We focus particularly on the consequences of the Beagle conflict in 1978, when the dictatorships of the two countries almost started a war. In the territory under analysis, this episode impacted daily life and the perception of the Other, historically characterized by a cross—border relational dynamic.
