Abstract

Building stones utilized on façades in the city centres of the three largest cities in the Free State of Saxony (Germany), Dresden, Leipzig, and Chemnitz, were recorded for a comparative study and related to the age of the buildings and to their use for distinct building elements. The cities show different patterns of stone utilization according to their geological background and historical development. Local building stones quarried nearby dominate until the middle of the 19th century, when the development of industries and infrastructure started to facilitate the delivery of a greater number of stone varieties from further afield. The use of natural stone for certain construction elements on buildings has been controlled not only by functional aspects and appropriate technical properties but also by fashion, the economic background, and political restrictions. Additional recording of the weathering state of different types of building stones after long-term exposure allows a comparative assessment, thus giving useful hints on their long-term behaviour and durability.
