The text aims to investigate the relevance of the concept of"public space" and the continuous variations which have changed its meaning. Going beyond the concept of public space, the author can understand the semantic boundaries of this definition: Today, relational spaces and shared spaces are the forms with which people can express the concept of public space.

Contemporary public spaces are defined, as the residual places that come from the abandonment of industries. The large mono-functional voids, which originate from industrial dismantlement, should be strategically reconsidered as new shared public spaces, where the integration between different functions leads to reactivate new forms of re-using of built space. 展开更多
