With the emergence of nodes between different disciplines that speak of the city or the urban, the text seeks to deconstruct the concept of public space. A discussion between authors of fields such as anthropology, sociology, geography, urban planning and architecture is presented. The dissolution of boundaries between disciplines and the various forms of theoretical and methodological approach of these are evident when one elaborates a key relationship: the subject and the living space. In the article, certain notions associated with the concept of public space are mentioned: territory, place and landscape; inevitably emerge from these disciplines that give meaning, but deconstruction now states that anthropology-for example- precises contribution of macro visions, while urbanism cannot ignore the preponderance of subject for studying, planning or design of open spaces. This, seen as a challenge to each of the disciplines involved, carries the possibility of the emergence of new research questions and put on the table how the concept has changed, remaining in force. Also, this possibly questioning those voices that announce the death of public space.
