Olszyna is a village in the administrative district of Gmina Trzebiel, within Żary County, Lubusz Voivodeship, in western Poland, close to the German border.[1] It is the site of a major border crossing on the E36 motorway connecting Berlin, Germany with Wrocław and Kraków in Poland. It lies approximately 4km (02miles) north-west of Trzebiel, 260NaN0 west of Żary, and 610NaN0 south-west of Zielona Góra.
Since the Middle Ages, the village was at various times part of Poland, Bohemia (Czechia) and Saxony. In 1815, following the Congress of Vienna, it was annexed by Prussia, and from 1871 to 1945 it was also part of Germany, before it became again part of Poland following the defeat of Nazi Germany in World War II.
