The article describes stone pavements forming the surface of the Old Market Square in Poznań. In the context of postulates of replacement of a historical stone surface with modern paving, the authors took the position that the quality as well as the amount of existing rock material is fully sufficient to carry out its renovation. First and foremost, it should concern the existing granite-gneiss, and more rarely basalt, quartz and porphyry paving stones, as well as granite paving slabs and granite curb stones.
The article presents several examples of historical fragments of streets of Poznań in the so-called Upper City with preserved granite gutters, stone pavements with cube dimensions 18 X 20 cm and 10 X 20 cm. Attention was also paid to the presence of setts made of basalt basin, as well as to the roads paved with fieldstone. These increasingly rare fragments of metropolitan streets should be subject to historical and architectural protection. They should be treated as the historic fabric of every city with a long and significant tradition.
