Local materials in the regeneration of urban space of the historic centre of the Metropolitan City of Naples.

The contribution is part of the studies conducted by the Urban Plan-ning Board, Land Management, Envi-ronment Laboratory for the “metropoli-tan city” and the Big Project “Historic centre of Naples, enhancement of the UNESCO site”. Among the issues under discussion, very important for the 92 municipalities of the Metropolitan City, is the preservation of different urban identities which, although united admin-istratively, are claiming their own cultural profile rooted in the urban space, in the architecture of places and in local resources. The work is based on the principle that the use of local resources affects the quality and perception of urban space and, as evidence of be-longing to the place, it is necessary to deal its exploitation under sustainable auspices.
