This document presents the construction and application of VOICES AND MEMORIES, which is a didactic sequence where the main elements are established from which theoretical bases are taken and a pedagogical proposal is formed where topics such as: Chair of Peace, the Post-conflict and the Collective Memory within it. The main objective was to incorporate the Chair of Peace through VOICES AND MEMORIES, to build the Collective Memory around the Post-Conflict in the tenth-grade students of the Julio Cesar García High School. In order to answer the problem question, we rely on the approaches and postulates of the Pedagogies of Memory, to direct the Chair of Peace towards a more intrinsic sense and produce a greater impact, so that reflection will be generated within the classroom and thus achieve the construction of Collective Memory. Subsequently, a classroom application was carried out from which the final results reside with which the conclusions and recommendations towards the institution were generated.
