    False patina is a common phenomenon in polluted urban atmosphere, which is characteristic for Cracow. The outer crusts of limestone and sandstone from architectonic elements of Wawel Hill were studied. The analysis include phase (optical microscopy, scanning electron microscopy SEM, X-ray diffraction XRD) and chemical analysis (energy dispersive spectrometry EDS, atomic absorption spectroscopy AAS). Among identified phases, at the surface of the stone analyzed gypsum, Si-Al glass spheres, iron oxides spheres, fly ash, calcium, quartz, feldspar, phosphate phases and organic matter were observed. The majority of examined weathered outer crusts revealed higher than unweathered stone concentrations of some elements: Zn, Mn, Fe, Ba, Cd, Pb, Cu.
