Which Nazi extermination camp was built near the Polish village of Bełżec?

Bełżec extermination camp was the Nazi killing center built near the Polish village of Bełżec. It operated in occupied Poland from March 1942 until June 1943 as part of Operation Reinhard, the plan to murder Jews in the General Government.

Most victims were deported from ghettos and killed soon after arrival in gas chambers using carbon monoxide from engines. Historians estimate that about 600,000 Jews were murdered at Bełżec, along with an uncertain number of Roma victims. The camp was dismantled, and the site was disguised to conceal the crime.

Bełżec is often confused with Chełmno, which used gas vans, or Auschwitz-Birkenau, which operated on a larger and longer scale. A small prisoner revolt occurred at Bełżec in 1942, but only a few prisoners are known to have survived the camp and the war.
