During World War II, Jodensavanne was used as an internment camp for a group of alleged Dutch Nazi sympathizers (National Socialist Movement NSB) brought over from Indonesia. They were interned for five years. The camp was located some 500m south from the synagogue. During their internment the detainees had to clear the cemeteries of Cassipora and Jodensavanne of overgrowth and they also documented the Jodensavanne Cemetery. Many bricks from the synagogue were purposely used to build their quarters and drainage. Some years after the camps were demolished in the 1950s, the Forest Service (LBB) planted 4 ha of pine trees (Pinus caribaea) as part of their reforestation project.
