Geology and paleontology lovers will find it worth their while to visit a number of places in the Kazimierz surroundings. In Bochotnica, a former chamber rock quarry where the Geological Documentation Site “Ścianka Pożaryskich” (Pożaryski Wall) presents a unique in Europe, clearly seen layer of the so called hardground which separates the Mesozoic from Cenozoic era. Next to the Vistula river in Kazimierz, there is another quarry which used to be excavated until the early 1980s for limestone - the so called bedrock, using a surface mining technique. All the historical town buildings in Kazimierz were made from the above mentioned stone. If lucky, one can spot fossils in the quarry 500 m wall which date back to the upper Cretaceous.
