دانلود کتاب Natural Stone and World Heritage: UNESCO Sites in Germany

There are many UNESCO World Heritage Sites in Germany. Most of them are built with natural stones. These sites are commonly presented to the public with a lot of information regarding historical, cultural and artistic aspects. Mostly, there is no focus on the main building material if it concerns natural stones. This work aims to show that it is precisely the natural stone that lends the sites their distinctive character. The used stones demonstrate the context and the interaction with the geology of the surrounding countryside as well as possibilities of transport and treatment. They reflect the culture and society at the time of the building phases. The second part of the work presents the most important stones that were used at these sites, along with their occurrences, aspects of quarrying in historical times and of course their petrographical, mineralogical and technical features. It is shown how these features influence the weathering of the stones and how restoration of stones is carried out. The book will serve as a useful source book for geologists, archaeologists, architects, representatives of the natural stone industry, historians and cultural heritage management professionals specifically, and for academic and nonacademic communities, travelers and tourism industry operators in general.
