The 37 cm thick carbonate flowstone layer found in a gallery of abandoned medieval mine in the Kutná Hora ore district (65 km E of Prague) started to grow about 500 years ago. Re-opening of the gallery in the 1960s terminated its growth. The relationship of calcite 18 O to climatic changes was studied in a vertical profile (42 samples), covering the whole thickness of the flowstone layer. Assuming constant growth rate, an arbitrary time scale was attributed to individual sampling points. The oxygen isotopic data of flowstone were compared with temperature data published by Brázdil (1994) and Mann et. al. (1999), and with isotope temperature obtained from 13C values for tree-rings from the Black Forest (Lipp et al., 1991). These comparisons show that changes in the 18O values of flowstone were dominantly controlled by changes in 18O values of water feeding the gallery. A good agreement between the  18O curve for summer temperature indicates that summer precipitation was the main source of water penetrating into gallery.
