Memorial Museums and dissonant collections: a conservation approach

This paper examines the role of memorial museums in the conservation and interpretation of dissonant heritage collections, understood as objects associated with traumatic historical events, conflicts, and human rights violations. Unlike traditional heritage approaches that emphasize aesthetic value and restoration to an original state, this study proposes a methodological framework that prioritizes the historical, ethical, and social significance of artifacts, treating them as material testimonies of survival and documentary evidence of past atrocities. The paper analyzes how memorial museums manage everyday objects originating from contexts of violence—such as concentration camps, dictatorships, and divided societies—and how these artifacts are transformed through documentation, stabilization, and musealization into documentary proof of crimes against humanity and educational tools for human rights awareness. The research proposes a binary and holistic methodology for the preservation of dissonant collections. The conceptual pillar is based on critical conservation, integrating ethical principles such as social legitimation, recognition of the moral ownership of victims and survivor communities, and the preservation of the patina of trauma, understood as the material traces of historical suffering. The operational pillar focuses on preventive conservation and risk analysis, applying international standards and vulnerability assessment models that consider both the physical fragility and the symbolic load of heritage objects. The study is supported by several international case studies carried out in institutions dedicated to memory heritage, including research residencies at the Auschwitz-Birkenau State Museum, the Stiftung Berliner Mauer, and the Museum of Memory and Welcome in Italy. It also examines conservation and collection management practices involving highly sensitive artifacts such as deportation wagons, wooden barracks, and original fragments of the Berlin Wall. The paper concludes that the conservation of dissonant heritage should be understood as a communicative practice and a civic responsibility, in which technical decisions are inseparable from ethical and social considerations. By safeguarding these fragile material testimonies, memorial museums contribute to preserving historical evidence, strengthening collective memory, and promoting human rights and a culture of peace.
