What happens if the notion of cultural heritage is put in relation to commons? Making up variable social areas of sharing, the commons have throughout history been offering various kinds of alternatives to partition, separation, privatization and segregation. However, the commons have been negotiated, competed, challenged, and may therefore be one of the true treasures for heritagization: cultural heritage is one of few contemporary notions that may provoke and complicate current simplified and homogenized understandings of the past. These issues, with a particular focus on space and place, as social imaginary and as practice, was addressed in an experimental seminar-series Heritage as common(s) Common(s) as heritage, within the context of Critical Heritage Studies, University of Gothenburg. This volume is a collection of these contributions, and the first volume in the publication series Curating the City.
