Abstract

For several decades, the conservation and maintenance of the historical architectural heritage in Italy have become one of the central problems within the scientific community of architects, restorers, and engineers. In fact, historic buildings represent not only an important symbol of the country’s culture but also a significant economic resource linked to tourist flows. Unfortunately, many historic buildings are in a state of neglection or in a dangerous state of conservation. It is therefore important to activate a series of actions to preserve and conserve this built heritage. In this context, a transdisciplinary approach that includes an accurate historical, dimensional, and material knowledge has fundamental importance to allow a correct design for restoration actions and the possible reuse as well as to allow this heritage to be usable and active. This article presents this integrate approach carried out for the specific case of the Basilica of the Beata Vergine Assunta in Guasila (Sardinia) with a particular focus on the results obtained from historical-documentary investigations, geomatics and petrographic surveys. These studies have been a fundamental base of knowledge for the last interventions of safety and extraordinary maintenance of the monument implemented in 2019
