After the outbreak of the Second World War Otwock became the location of a Jewish ghetto in which more than 10,000 Jews were assembled.
The town commemorates the breakup of the ghetto, during which residents were transported to Auschwitz and Treblinka, with a ceremony every August 19.
“Here, in the mass grave, some 2,400 Jews from Otwock who were murdered in this place by the German occupiers are buried in August 1942,” the plaque on the stone reads, according to the Israel-based Coordination Forum for Countering Antisemitism.
“We will remember their tragedy and all the Jewish citizens murdered in our town.”
