Bronna Góra (or Bronna Mount in English, Belarusian: Бронная Гара, Bronnaja Hara) is a name of secluded area in present-day Belarus where mass killings of Polish Jews were carried out by Nazi Germany during World War II. The location was part of the eastern territory of occupied Poland, which was invaded by the Soviet Union in 1939, and captured by the Wehrmacht two years later in Operation Barbarossa. It is estimated that from May 1942 until November of that year, during the most deadly phase of the Holocaust in Poland, some 50,000 Jews were murdered at Bronna Góra over execution pits. The victims were delivered in Holocaust trains from the wartime Jewish ghettos in Brześć, Bereza, Janów Poleski, Kobryń, Horodec (pl), Antopol and other places along the western border of the Reichskommissa
