Section of Cold War Tunnel “Found” – Used to Spy on the Russians in Berlin


Exposed part of Tunnel

Fifty six years after the cold war a section of an ingenious tunnel built by the British and U.S. governments to spy on Russian phone conversations. The tunnel become exposed in a forest some 150 kilometers from the German Capital.

Built in 1955, the 450-meter-long tunnel,  spanned from Rudow in West Berlin to Alt-Glienicke in Soviet-occupied East Berlin. Allied intelligence agents tapped into the Russians underground  telephone cables,  they were able to record 440,000 phone calls, achieving a clearer picture of the maneuvers the Red Army was making in eastern Germany at a time. This all took place when nuclear war deemed a possible threat.

A portion of the western tunnel that was preserved  can be viewed at the  Allied Museum in the former American sector of Berlin. The fate of the eastern part of the tunnel had remained unknown til now. After discovering it the Soviet authorities dug it up in 1956.

“It seemed to have vanished without a trace,” said Bernd von Kostka, a historian at the Allied Museum. “I looked through the East German Stasi files, and there was nothing to be found about its whereabouts. We assumed it had been melted because it was made of valuable metal.”

The find has become one of  the missing piece of the puzzle, It may take decades to solve it completely, as more access to intelligence files about the construction come to light and discovery of more of the tunnel — a tale worthy of a John le Carre novel — the files are still restricted.

The man who discovered the buried segment is Werner Sobolewski, 62, formerly employed in a civilian capacity by the East German army. He was chopping wood in his local forest in Pasewalk, near the Polish border north of Berlin, when he stumbled across the wide metal pipe. He remembered it being used for military exercises at the local barracks, where he had worked before the fall of the Berlin Wall.

He recalled too that it was then rumored to have been a part of the Allied spy tunnel, infamous throughout eastern Germany after the Soviets exposed it in a major propaganda campaign in 1956. He contacted the Allied Museum and Kostka traveled to Pasewalk to identify it last week.

“We would like to have it in the museum so that we have a part of the eastern tunnel,” Kostka said in an interview at the Allied Museum. “The sections we have are from the western side. It shouldn’t stay buried underground.”

The western tunnel segment is a prize exhibit at the Allied Museum, which is also home to the original Checkpoint Charlie guard-hut and a Royal Air Force Hastings plane used in the Berlin airlift of 1948 and 1949.


Listening Post in Vienna Tunnel

Displays describe the complexity of building the tunnel and tapping the wires. The British had already constructed similar underground listening-posts in Vienna and brought the idea, manpower and know-how to the project, Kostka said. Codenamed “Stopwatch” by the British and “Gold” by the Americans, it was funded by the U.S. at a cost of $6.7 million (then a vast sum) and operated jointly by the CIA and the British SIS.

Yet the KGB learned about the tunnel when it was still in the planning stages — thanks to intelligence from George Blake, the notorious British double agent who was later imprisoned, then escaped to the Soviet Union. Strangely, the KGB concealed its existence from the Soviet military because they wanted to protect their valuable mole.

The tunnel operated for 11 months and 11 days, intercepting some of the Red Army’s most secret communications, including those between Moscow and the military headquarters in East Berlin. Historians do not know why the Soviet authorities chose to expose it when they did, on April 22, 1956. The reason is still buried in the Kremlin’s files.

“It was clear that the tunnel had a finite lifespan and would be discovered one day,” Kostka said. “But the Allies expected the Soviet authorities to sweep it under the carpet.”

Instead, they held their first international press conference in 11 years of occupation and bussed in as many as 50,000 East German citizens so that they could see first-hand the treachery of the West.

Yet it was also a propaganda coup for the U.S. intelligence services as the tunnel’s ingenuity impressed American observers.

“It’s a great Cold War story,” said Kostka. “Each side could say they won.”
