Risiera di San Sabba is a 5-storey brick-built compound that functioned during World War II as a Nazi concentration camp for the detention and killing of political prisoners, and a transit camp for Jews, most of whom were then deported to Auschwitz. SS members Odilo Globocnik and Karl Frenzel, and Ivan Marchenko are all said to have participated in the killings at this camp. Erwin Lambert is claimed to have installed cremation facilities. Today, the former concentration camp operates as a civic museum.
