The Cold War's best-kept secrets are underground — and they're giving tours now.
After the Berlin Wall fell, hidden GDR and Swiss Cold War bunkers surfaced. Author Michael Kloft tours preserved Stasi and NVA shelters, including sealed command centers for Honecker and Mielke, and abandoned missile sites. In Switzerland, “false chalets” and the alpine “Reduit National” fortress reveal underground defenses once kept secret. With exclusive access to military command bunkers, the film exposes relics of a vanished era’s paranoia.
