The last secrets! Operation Gold - The Berlin spy tunnel

VA DSM

On April 22, 2026, Berlin will celebrate an outstanding anniversary as the capital of espionage - the 70th anniversary of the legendary spy tunnel. Researchers and specialists from the Berlin Underworlds have tracked down and analyzed surprising news in the archives of the CIA, Stasi and a commission of inquiry.

Berlin, 1954: The city is an epicenter of the Cold War. The CIA and the British MI6 are secretly planning one of the most daring coups in intelligence history: Operation Gold. The spy tunnel extended from West Berlin some 330 meters into the GDR. From May 1955, the intelligence services intercepted over 400,000 telephone calls from the Soviet military from there - meaning they had direct access to the Kremlin's world of thought. The Soviet intelligence service ended the operation in April 1956.

But what the Western powers did not suspect: A traitor was already at the table during the planning. George Blake, a mole in the British secret service, had long since informed Moscow of every detail. While the CIA and MI6 invest millions in analyzing the intercepted conversations, the Soviets play a double game. Operation Gold tells the true story of technical genius, political hubris and the bitter taste of betrayal. A gripping piece of contemporary history about a tunnel that became a symbol of the absurdity and danger of the nuclear age. We are looking forward to the revelations about a legend of the Cold War.
