The commons today constitute a hotly debated topic with wide research range spanning from the natural resources to social and digital goods. However, discussions on heritage as commons are limited, considered mostly as part of the state politics and economics agenda. This chapter attempts to provide an initial sketch of the emerging field of heritage commons, based on empirical work carried out by the author in Greece; a country at the forefront of the development of the 'cultural property' notion for heritage, currently negotiating the public texture of its monuments and cultural economy. Commenting on the state enclosure of the past and subsequent practices by other agencies within this appropriation, this chapter attempts to redefine heritage and its components, drawing on their social and economic values and the tripartite schema of the commons (resources, involved communities, regulatory frame) towards a more democratic governance perspective.
