Traces of disappearing heritage: upcycling of wooden vessels preserved in the vernacular architecture of a large river valley in Central Europe

The article presents a trend in rural and small-town architecture, in central Poland, consisting in the reuse of material from river-going vessels. As part of the research, twenty objects (existing and non-extant) were identified that had been constructed using material from wooden vessels that had navigated the Vistula River in the past (nineteenth and twentieth centuries). There was also a reinterpretation of the origin of construction material from a farm building that had been moved in the 1980s from near the Vistula to one of Polish open-air museums. The results indicate that these are probably the last material traces of a boat mill that operated on the Vistula in the late nineteenth century. Also, many preserved millstones embedded in buildings located near the Vistula seem to confirm this conclusion.
