The word “conservation”, when used in the context of preservation of built heritage, implies an intrinsically complex concept that evolved over time, since it has been influenced by the perception of history throughout time. This volume emphasizes why an understanding of the cultural evolution of the conservation approach must be considered a prerequisite for architects and engineers to cooperate in full harmony with historic-artistic culture for the preservation of global built heritage. In particular, the volume highlights how, during the second half of the last century, the preservation process also involved engineering, the science of making practical applications of knowledge, which, for a long time, made an uncritical use of techniques and materials and devised interventions on historical heritage that were heavily invasive. The volume also devotes special attention to the problems related to seismic risk, to which Italy, Greece and Portugal are particularly prone. Problems that emerge during the crisis and reconstruction phases are dealt with in detail, as well as the scheduled maintenance, as this latter approach always constitutes an improvement of the performance of the monument and is the most appropriate tool for the conservation of the built heritage. Finally, the volume collects examples of building restoration with case studies of many outstanding monuments. The work will appeal to professionals and academics in the wider fields of civil engineering (both geotechnical and structural engineering), architecture, art history, history of architecture, restoration and cultural heritage management.
