The photo shows the interior of this first Polish cathedral. It is probably here that Prince Mieszko I was the first to be baptized and inscribed Poland on the pages of Roman Catholic church history. The marble of the cathedral floor is engraved with the names of the Polish kings for whom Poznan was home and Poznan Cathedral a place of eternal rest.
