Schlacht um die Seelower Höhen
Lubusz Land was the site of fierce fighting on the Eastern Front of World War II in 1945. In February and March the battle for Kostrzyn nad Odrą (then "Küstrin") was fought, which resulted in 95% of the town being destroyed, making it the most destructed town of post-war Poland. In April the Battle of the Seelow Heights took place, ending in a Soviet-Polish victory. It was one of the last battles before the capitulation of Nazi Germany and the end of World War II in Europe.
