you would hardly believe how much masonry can tell if you “read” it carefully. as a member of a team of building researchers, i have learned to date and interpret masonry in recent years and me and my colleague doris schön (to whom i owe my thanks) have taken many photos of masonry probes on historic buildings during our projects. these show different stages in the development of masonry, which have been well researched for eastern austria in recent decades. due to the difficulty of translating the technical terms, i have left this poster in the original language of research, german.
