Paneriai (Polish: Ponary, Yiddish: פאנאר/Ponar) is a neighborhood of Vilnius, situated about 10 kilometres away from the city center. It is the largest elderate in the Vilnius city municipality and is located on low forested hills, on the Vilnius-Warsaw road.
The Ponary massacre (or Paneriai massacre, Polish: zbrodnia w Ponarach) was the mass-murder of 100,000 people, mostly Polish Jews, by German SD and SS and Lithuanian Nazi collaborators by Sonderkommando collaborators (Special SD and German Security Police Squad Ypatingasis būrys units) during World War II and the Holocaust in Reichskommissariat Ostland. The executions took place between July 1941 and August 1944 near the railway station of Paneriai (Polish: Ponary), then in Poland and now a suburb of Vilnius, Lithuania. Some 70,000 Jews were murdered in Ponary, along with estimated 20,000 Poles and 8,000 Russians, many from nearby Vilnius.
