In the Kraków-Częstochowa Upland, there are numerous graves of soldiers from WW1 of the three clashing armies: the German, Austro-Hungarian and Russian. The first well-maintained war cemeteries were established already in the years 1917-1918. The largest necropolis can be found in a small village near Żarki - Kotowice. 1500 soldiers from all the fighting army, mostly Russians, Austrians and Germans are buried here.
