The article characterises the presence o f stone raw material in particular stages o f the construction o f Poznań cathedral (fig. 4). The authors describe the stone architecture of the entire surrounding o f the cathedral (fig. 2) and devote much attention to architectonic elements, the interior o f the cathedral, and sculpture (fig. 3, 5). The origin o f select stone raw material used in the architecture o f Ostrow Tumski in Poznań is depicted in fig. 1. Hopefully, this article will convince the reader that “mute ” stones can “speak” and become a valuable source for researchers dealing with the past.
