This monograph was conceived as a collection of visual templates designed to quickly identify various types of destruction on a real object in the field during its examination as part of preparatory work before restoration, repair, and so on. In the process of preparing the monograph, the authors were unable to find such a systematic and generalizing work in the domestic literature. The book can be used by practitioners and scientists working in the field of restoration, construction and repair of buildings, historians, ecologists, designers and other interested people, and also as a teaching aid students of relevant technical and humanitarian specialties.
