 During World War II, the Germans closed the park for Poles and Jews, and most of the conifers that remained from the city forests were cut down, the perennial garden was also liquidated, and tennis courts were built in its place (currently the Municipal Tennis Club).During the war, the bottom of the pond was also destroyed, which was not rebuilt until 1957.A reminder of the war are two cemeteries of Soviet soldiers killed in January 1945.
