Dismantling and rebuilding heritage. What does it means in terms of memory?

We present a research which principal aim is to study and understand all the processes related to heritage that the massive construction of dams and reservoirs entailed in the central decades of the past century in Italy. We study its repercussion not only in from a building restoration perspective but involving fields such as memory, politics, geography, sociology or anthropology in order to manage all the "reactions" that engage the topic of collective memory and therefore constitute an opportunity to build new concepts through which to analyse (and design) very contemporary fields of study that could be applied to improve strategies for the conservation of the values of villages in areas with high seismic risk or hydro-geological instability.
