The church in Kruszwica is an example of the Polish Romanesque architecture. The petroarchaeological researches have revealed the origin of stone material which is used in this building. We can distinguish erratic materials and sandstones. The main group in the first one are granites and granodiorites. Erratic material was collected in the vicinity o f the church. Sandstones were imported from the medieval quarries near Konin. Petrographical knowledge o f stone materials is useful especially in renovation and reconstruction works.
