By sacral-architecture and spectacular mass-events the subconsciousness of the masses was influenced by pseudo-religious ideas. The two cult rooms inside the North Tower were built to deepen the own "mission". In 1938, Siegfried Taubert was in charge of developing the castle, when Himmler inquired about the cost of installing a planetarium. To round off the subjects taught at the Wewelsburg SS school a teacher was sought who should draw cross-connections between astronomy and history and the folklife of the ancestors so that the historical and ideological schooling was to be enhanced and deepened by the "cosmic view" (kosmische Schau). According to the writer J. von Helsing, the recovered unknown flying object that crashed in the Schwarzwald (Black Forest) near Freiburg in 1936 was taken to the Wewelsburg castle, where a reverse engineering project was launched, reportedly leading to the construction of several very advanced flying machines towards the end of the World War II. This subject is often featured in popular culture and science fiction; The History Channel series Ancient Aliens features the Freiburg disc crash in their episode "Alien and the Third Reich" (Season 2, episode 5). Niederhagen Camp Just offsite of Wewelsburg was the smallest German KZ, Niederhagen prison and labour camp. Begun on June 17, 1940, the camp was completed the following year and named after Niederhagen Forest, the name Himmler had given to the forest outside the castle several years earlier. It began with 480 prisoners from Sachsenhausen, and grew to 1200, consisting chiefly of Soviet POWs and captured foreign labourers shipped to Germany, although early in its life it was also a gathering point for Jehovah's Witness prisoners. Correspondingly, a large percentage of the concentration camp inmates at Niederhagen who were working on the Wewelsburg Castle were indeed Jehovah's Witnesses, perhaps the only place where they constituted the core KZ population. During the SS's December 1942 Korherr Report it was reported to have only housed 12 Jews, all of whom had died. Of the 3900 prisoners held during the camp's existence, 1285 died of typhus and 56 were formally executed. In August 1942, the Allies began deciphering death tolls transmitted from the camps; Niederhagen had reported 21 deaths for that month. The camp was dissolved in 1943 with most of the prisoners resettled in Buchenwald, though several dozen prisoners remained behind, housed directly in Wewelsburg. Hauptsturmführer Adolf Haas, who had overseen the camp from its
