In mid-November 1941, at the time of the concentration of Jews in one quarter of Lwów, a number of Jews deemed unfit for work, mainly sick and elderly people and children, were taken by truck to Kajserwald and shot there by German and Ukrainian auxiliary policemen.
According to one testimony, Jews from Lwów were shot also in the southern part of Kajserwald, at the sand quarries known as Piaskownia, in 1942-1943. The total number of those shot there is not known.
