The square has always been the meeting place of the community. Piazza Matteotti is located in the heart of Foligno, in continuity with the system of public spaces of the historic center. This position in this complex system would seem to be enough to give the square features of normal usability and continuous use of space. Nevertheless, Piazza Matteotti is underutilized for most of the year, if not during specific events. The lack of a real design of this space has certainly generated some problems. The analysis of the urban system and in particular of this » resulting void » have revealed three main critical points: car circulation, which divide the square from the system of open spaces, morphology of the square, which makes it difficult to use, generating an «impermeable» architecture, green elements with a marginal role. The project works on these three points: transform the square into a point of arrival and no longer transit in relation to traffic; create a space that is permeable, able to connect and create relationships with the existing open space system; give to green element a role of absolute importance. These three design strategies are put into system by form, which finds its raison d’être in the historical trace of the buildings that were demolished and left space for the urban void.
