Bieleń
Bieleń (German: Weißensand) is a village in the administrative district of Gmina Trzciel, within Międzyrzecz County, Lubusz Voivodeship, in western Poland.
Prior to 1945 it was in Germany. After World War II the region was placed under Polish administration and ethnically cleansed according to the post-war Potsdam Agreement. The native German populace was expelled and replaced with Poles.
