ABSTRACT
However, in cities where new buildings have gone up, these have very often taken the place of what was there before, contributing to upsetting the pre-existing urban context; every district, however spontaneous and lacking in infrastructure, achieves a certain homogeneity in appearance as time passes, takes, so to speak, some form or other, even if it has no functional organization and, in some way, due either to natural ageing or to the modification brought about little by little, by community life, succeeds in assuming the form of a precarious but recognizable environmental balance with the particular caracteristics of an urban district.
