Restauro e rilettura del passato. Contaminazioni e ibridazioni in 150 anni di restauri a Villa Adriana, Tivoli

The layering of interventions conducted over the past 150 years in Villa Adriana is an expression of the history of restoration itself, impressed in the stones with the distinctive signs of each historical period. The archaeological site restorations show the discipline update processes, as a concatenation of principles translated into practical deeds. Each update of thought implies a reinterpretation of the criterions that have regulated the previous interventions, opening perspectives to "new frontiers". "New" intended as proper of each time, but with the common purpose of finding new solutions to the constant human challenges directed to the transmission of heritage ofthe past. In 150 years of activity, contaminations emerge, becoming new opportunities for the conservation challenge. They create "hybrid architectures" that sometimes maintain their image, but not their functioning. Addressing these themes to the constant updating restoration culture, a study of the past restoration is being proposed. Presenting a criticai reading of the works conducted in Villa Adriana, the meaning is to emphasize how each single orientation is the testament of the previous one update; a temporary and partial renewal which can be still be subject of thoughts and reversals. The debates on works conduction never end themselves, on the contrary, they become cultural activities narrated through the approaches of different directors succeeded in the conservation site. A history which, preserving the past, face the future, constantly looking for "new" measurement and balance.
