This chapter introduces the need to safeguard built heritage through digital innovation, emphasizing the threats posed by both rapid-onset disasters, such as earthquakes, and slow-onset processes linked to climate change and urban heat island. It presents the main objectives of the monograph, focusing on developing an integrated digital system capable of combining multi-scale data, vulnerability assessments, and risk mitigation strategies. The chapter highlights key innovative aspects, including the comprehensive approach to digitization—not limited to geometric and material knowledge, but extended to vulnerability and risk analyses—and the creation of a dynamic digital platform for heritage management. Finally, it outlines the structure and main contents of the book, offering readers a clear roadmap through the methodologies, tools, and conservation strategies discussed in the following chapters.
