Monumentos em Ação is a territorial performance that seeks to reclaim public space, making present the absences that inhabit it. The performance consists of a journey where performers and spectators advance together in the task of collectively constructing an act of memory. This journey is accompanied by an audio guide containing testimonies from people living in the area. Through historical investigation, the performance interrogates and reflects on the moment we live in: How many different perspectives can emerge from a single event? Are we responsible for keeping our past alive? By embracing a plurality of voices, the performance seeks to decolonize the idea of memory, offering spectators the experience of a collective reconstruction of history. Participants are invited to use their bodies to create anti-monuments. In doing so, the performance emphasizes that the space of memory is built by people, not by monuments. This decolonizes the notion of memory and memorial, stressing the idea that memory is human-made rather than fixed in stone.
