The NSA's Secret Spy Hub in Berlin

According to SPIEGEL research, United States intelligence agencies have not only targeted Chancellor Angela Merkel's cellphone, but they have also used the American Embassy in Berlin as a listening station. The revelations now pose a serious threat to German-American relations.

It's a prime site, a diplomat's dream. Is there any better location for an embassy than Berlin's Pariser Platz? It's just a few paces from here to the Reichstag. When the American ambassador steps out the door, he looks directly onto the Brandenburg Gate.

When the United States moved into the massive embassy building in 2008, it threw a huge party. Over 4,500 guests were invited. Former President George H. W. Bush cut the red-white-and-blue ribbon. Chancellor Angela Merkel offered warm words for the occasion. Since then, when the US ambassador receives high-ranking visitors, they often take a stroll out to the roof terrace, which offers a breathtaking view of the Reichstag and Tiergarten park. Even the Chancellery can be glimpsed. This is the political heart of the republic, where billion-euro budgets are negotiated, laws are formulated and soldiers are sent to war. It's an ideal location for diplomats -- and for spies.

Research by SPIEGEL reporters in Berlin and Washington, talks with intelligence officials and the evaluation of internal documents of the US' National Security Agency and other information, most of which comes from the archive of former NSA contractor Edward Snowden, lead to the conclusion that the US diplomatic mission in the German capital has not merely been promoting German-American friendship. On the contrary, it is a nest of espionage. From the roof of the embassy, a special unit of the CIA and NSA can apparently monitor a large part of cellphone communication in the government quarter. And there is evidence that agents based at Pariser Platz recently targeted the cellphone that Merkel uses the most...

How embassy eavesdropping works

The key visible feature of most embassy and diplomatic sites that give away their secret spying missions are large windowless areas on top floors, and also sheds or hangers on the roof which are designed to look as though they might contain lift or air conditioning apparatus.

At the US Embassy in Berlin, the lighter coloured panels on the south west, north west and northeast corners of the rooftop surveillance facility are dielectric "radio windows" which allow all types of radio signals to reach collection and analysis equipment on the roof and floor directly below.

The "radio window" panels are made of special material which does not conduct electricity. That is so weak radio signals coming in from all corners of the city are not diminished (attenuated) as they pass into the building and reach the sigint (signals intelligence) antennae.

Usually, dielectric window panels for signals intelligence work are made of plastic or fibreglass. They are often shaped and coloured to look as though they are a normal part of the building, or are special architectural features...
