During World War II about 70% of the town's buildings were destroyed. In 1945 between the days of 8–10 February Red Army soldiers mass-murdered 150 German pensioners in an old-people's home and 500 psychiatric hospital patients in Lubin.[1] As a result of border changes promulgated at the 1945 Potsdam Conference, the town, lying east of the Oder-Neisse line, became a part of the Republic of Poland.
