East Germans escaping to the West via the open Berlin border were subject to close interrogation about life in their former homeland, whilst staying in emergency accommodation centers such as Berlin Marienfelde. Some agents even managed to convince the refugees, so recently arrived from the East, to return to the GDR and spy for them there.
The early period also saw the development of more sophisticated methods of spying – in the mid-1950s, the American and British intelligence services tunneled 450 metres underneath East Berlin and tapped into important telephone wires. »Operation Gold« as the project was called was betrayed by a KGB double Agent who worked for the MI6 and the Soviets later »discovered« the operation.
All these and many other stories can be traced in their fascinating detail at the German Spy Museum Berlin. With a range of unique testimony from eye-witnesses, original espionage equipment and modern multi-media installations, the exhibition provides a unique slant on what represents an often breath-taking story. For example, our interactive SpyMap pinpoints the location of historic events, persons and locations across Berlin. The modern appearance of Berlin often obscures what is a fascinating past and can only be accessed by a visit to our museum.
