The historiographic productions on the memories of the workers victims of the State terrorism of the 1970s in Argentina, have been very scarce. This article shows, in regional-local key (city of Ensenada, Buenos Aires province), the ways to elaborate absences of those who have constituted the highest percentage of disappeared and murdered in Argentina (2003-2015). Their representations are described and analyzed through territorial marks, warning that they function as tributes, commemorations and rituals, at the same time that they act as symbolic reparations for their relatives and close friends.
