However, due to the lack of sources like treatises and naturalistic depictions we know comparably little about the cranes they used. To refine our knowledge of high medieval cranes this paper discusses their construction and technical capabilities based around preserved machines and finds examined with the methods of building archaeology.

Proceedings of the 8th International Congress on Construction History N2 - The relative chronology and ideas behind development in medieval building services are often difficult to prove. Especially concerning the High Middle Ages, the acquisition of knowledge is hindered not only by the large amount of unpublished unknown or destroyed objects, but also by the lack of written sources. With the two towers of Besigheim in southern Germany, well-preserved examples of stately architecture extant to this day. A detailed Building Archeological survey of them can offer us a regionally and temporally fixed insights into building services, their variations and the ideas which underpinned them.
