Prior to 1945 the town was part of Germany and settled in large majority by Germans . After World War II the region was placed under Polish administration by the Potsdam Agreement under territorial changes demanded by the Soviet Union . The town , having been settled by German-speakers for centuries was voided of its native population , for the town to be resettled with Polish citizens new to the region . Since the town had not an established Polish name , the new name of Gryfów Śląski was found . Some of the new inhabitants were Polish refugees from regions east of the Curzon line , the Kresy , from where they had been displaced by Soviet authorities in accordance to new borders decided at Yalta Conference , while most new settlers were re-settlers from Central Poland . Gryfów Śląski is twinned with Bischofswerda in Germany , Raspenava in the Czech Republic and Gryfice in Poland
