This article analyzes the management and representation of memory in two regional memory sites in Colombia: the Trujillo Monument Park and the House of Memories of Conflict and Reconciliation in Cali. Through a comparative approach, the networks of actors committed to historical memory are examined, focusing on “bottom-up” approaches led by victims and communities, and “top-down” approaches promoted by institutions. The study explores how these dynamics influence the construction of narratives, social appropriation, and the relationship of these spaces with memory policies in the country. It reflects on the challenges and opportunities for the management and representation of memory as a process that seeks not only to preserve the past but also to transform the present and future, fostering a democratic culture.
