In this article I present an exegesis of the performative research "Theatre and memory. Strategies of (re) presentation and performative elaboration of children's traumatic memory" whose general objective was to explore performance strategies to stage testimonies of people who were children during the dictatorship in Chile. The project was conducted in two phases: in 2008 the testimonies were collected and we developed a first theatrical laboratory, in a second stage, developed between 2011-2012, we created the testimonial play Pajarito Nuevo la lleva, presented in various theatres and memory sites in Santiago de Chile. In the present article I identify different strategies of mise-en-scene and embodiment of the collected testimonies, accounting of some possibilities of theatrical reelaboration of post-conflict memories.
