This Case Study archive is a collection of both MAPS project researchers’ papers on Nonuments in their respective countries as well as selected papers from Nonument symposia and from the forthcoming book. Whether the papers examine individual Nonuments, the wider context of dealing with post-traumatic and conflicting Nonuments, the emancipatory potential of abandoned structures and infrastructural projects or new methods for preserving architectural heritage, their aim is to open up space for discussion about the politics of space, and its impact on the communities and everyday life within them. In a time when we are witness to less-than-transparent trends of space management, as well as rapid and radical interventions into the structures of cities, these processes are always accompanied by the shrinking of public space. This calls for consideration on the specifics of architectural heritage or cultural heritage in general.
