Stock Photo - 04 August 2021, Rhineland-Palatinate, Mainz: Markus Wittköpper, archaeological restorer specialising in wet wood conservation, cleans the piece of an ancient wooden water pipe covered in mud from the Stadtmuseum Ahrweiler with a fine jet of water in the restoration workshop of the Museum für Antike Schifffahrt. The flood disaster that raged in July had also hit the depot of the Stadtmuseum Ahrweiler. In order to quickly take care of the collection objects and save them if possible, the Roman-Germanic Central Museum, Leibniz Research Institute for Archaeology (RGZM), set up cleaning stations in the workshop of the Museum of Ancient Navigation.
