A project that aims to examine those so-called microworlds born on the margins of a very complex urban system and which, over time, have assumed the unlikely forms of autonomous reality and detached from the central city pole, Taranto. Marginal peripheral districts (such as 'Paolo VI, Tamburi, Salinella') which constitute the 'internal suburbs' and which are distributed as 'urban filaments' in industrial areas. A landscape contaminated by the processes of industrial expansion, as well as urban/residential of a popular type... A clear example of Shrinking City, a city in serious demographic contraction: a phenomenon that initially spread in the United States and caused by the sudden conversion of the 'industrial' reality to 'post-industrial' (examples are Saint Louis in Missouri; Youngstown, Cincinnati, Cleveland and Toledo in Ohio; Pittsburg in Pennsylvania; Detroit in Michigan). The case of Taranto appears as a wrong total systemic conversion that has not yet fully occurred due to the various industrial realities present, active and inactive, which have always represented an ecological threat to the landscape and above all to the quality of life of the inhabitant forced to live too close to them.
