Declassified – The Secret of Teufelsberg

On October 3, 2024, the new temporary exhibition “Declassified – The Secret of Teufelsberg” opens at Teufelsberg, offering a deep dive into the fascinating and largely unknown history of this unique site. Designed and curated by °pha Architekten BDA from Potsdam under the direction of curator Arndt Hermann, the exhibition explores the historical events that have shaped Teufelsberg over the past 100 years.

A Place Full of History and Contrasts

Teufelsberg, the largest debris hill in the world, is not only a striking geographical landmark but also a focal point in German history. In the early 1900s, the area was used as the hunting grounds of the German Kaisers, later becoming a retreat for Berlin’s residents. However, its significance changed dramatically during World War II, when Adolf Hitler laid the foundation stone for his planned world capital, Germania. After the war, the hill was formed from 26 million cubic meters of rubble, burying the ruins of the unfinished Nazi structures beneath it.

The real intrigue, however, comes during the Cold War. Teufelsberg became a central listening post for the Western Allies. Around 2,000 soldiers worked here to monitor the communications of the Eastern Bloc and gather valuable intelligence. These espionage activities, including a scandal involving the leaking of secret documents to the Stasi and KGB, form a key part of the exhibition.

What Can You Expect?

The exhibition takes visitors on a journey through time, exploring the hidden corners of the former listening station. In the dark, secretive hallways of the facility, the history is brought to life through large-scale photographs, audio stations, installations, and film projections. Interviews with eyewitnesses, including an American intelligence analyst and the former editor-in-chief of Der Spiegel, shed light on Teufelsberg’s geopolitical and security importance during the Cold War.

One of the most impressive aspects is the way the exhibition is staged within the original rooms of the listening station, which have been carefully preserved to maintain the building’s authentic condition. This unique setting creates an atmosphere of secrecy and tension, transporting visitors back to the Cold War era.

The exhibition not only provides insights into the history of Teufelsberg but also offers a glimpse into the world of international espionage. Visitors will learn how both Western and Eastern intelligence agencies operated from Teufelsberg and what kind of information was collected. These secretive operations shaped international politics and led to German-American scandals, echoes of which can still be seen in modern-day revelations, such as the Snowden affair.
