Urban formations are like a text composed of overlapping, stratified and interfering signs, deeply inscribed in the traces of the ground, thanks to which we are able to understand the permanence and variability of space and time. More specifically, urban stratifications allow us to enhance not just the remote past, but also the recent past, by inducing us to interpret a place correctly. The challenge of today is to look at the reality, to start again from the place and to give new shape and identity to the built. This means defending the land and the environment. It means redeveloping or starting again that is from urban material that cannot be broken up and which generates indispensable qualitative change that we must be capable of grasping if we are to discover the seed of community identity under the dust, seeking elements in the materials of towns and cities to propose a new role, a structuring function of new qualities which are also a search for our roots.
