KRITIS Geheimhaltung: Warum Deutschland antike unterirdische Strukturen auf modernen Infrastrukturka

Why do forty kilometers of tunnels beneath German cities not appear on any federal map, even though city archives have known about them for three hundred years? In this documentary, we reconstruct the case of a pensioner from Oppenheim whose kitchen floor collapsed above an eight-meter-deep shaft, and uncover how a single classified document from the Federal Office of Civil Protection and Disaster Assistance from 2009 caused entire underground structures to disappear administratively. We follow three leads: Erika Brandt in Oppenheim, the fatal collapse of Ronald Petersen in Freiberg, and the dismissal of geologist Dr. Martin Hauschild. Along the way, we discover a parallel military cavities register maintained by the German Armed Forces in Euskirchen, which has been secretly recording tunnels, earth houses, and medieval cellar labyrinths since 1962—tunnels that are officially not supposed to exist in civilian administration. You'll learn what Annex 3 of the BBK risk analysis actually contains, what role the Cold War-era Civil Defense Pact (ZIVPAKT) plays in it, and why 374 German cities with documented pre-modern subsurfaces have been excluded from the nationwide risk assessment. This is an investigation involving citizens' associations with ground-penetrating radar, classified files until 2042, and a list of seven cities whose order is anything but random.
