Bronna Góra (or Bronna Mount in English, Belarusian: Бронная гара) was a secluded location of mass killings of Polish Jews in the eastern territory of occupied Poland during World War II. The area was invaded by the Soviet Union in 1939, and captured by the Wehrmacht two years later in Operation Barbarossa of 1941. It is estimated that from May 1942 till November of that same year, during the most deadly phase of the Holocaust in Poland, some 50,000 Jews: men, women and children were murdered there over execution pits.
