Stasi Field Station „Park“
#thread

A square functional building on the outskirts of the old capital Bonn in West Germany. The #Stasi operated a #SIGINT base here, disguised as the GDR's diplomatic permanent representation in Bonn 1/6 Image
The full scale of GDR espionage in West Germany only became known after the fall of the Wall. An important #Stasi spy station was located in Bonn at Godesberger Allee 18. The "Ständige Vertretung" (StäV) of the GDR - a kind of embassy. Active 1974 to 1990. Code name "Park" 2/6 ImageImageImage
By order of the GDR, the building was increased by one floor (3 to 4). For good reason. State-of-the-art listening technology was set up there. Code name "STEUERUNG 1“ In a specially secured area, more than 30 receivers and corresponding recording equipment were installed 3/6 ImageImage
#SIGINT experts of the Hauptvewaltung III (HA III) had the West German government and intelligence services in their sights #BND #BfV. The Stasi foreign intelligence unit HVA had also occupied a separate area with its own espionage gear 4/6 Image
Whether car phone, fixed line numbers or intelligence services' radio - everything was collected and forwarded to East Berlin. One important target is West German counterintelligence #BfV. Its watchdogs are an open book for the #Stasi 5/6
For this purpose HA III had a monitoring post on the premises of the Soviet trade mission in Cologne - code name "Steuerung 1b“ 6/6👇

Russian cultural institutions raise eyebrows in Western counterintelligence. Not without reason. They are seen as a gateway for #SVR #GRU and #FSB. The A.S. Pouchkine Cultural Centre 32, rue Goethe in Luxembourg is also suspected of espionage. A few interesting details 1/10
In an undated interview, former Rossotrudnichestvo official Tatiana Poloskova criticises the cultural institution's involvement with intelligence services. Poloskova is a political analyst and state advisor of the Russian Federation. She knows Putin's power apparatus 2/10
Tatiana Poloskova: "Everyone knows that they are from the #FSB. Of course, no one wants to say that, but in the host countries this label is firmly attached to them. I think this is not so much the result of propaganda as a mistake in our personnel policy“ 3/10 Image

Moscow's ears in Vienna
#thread

A look into the enclave "Little Russia" Erzherzog Karl Straße in Donaustadt shows some interesting details. Since 1979, the compound has been seen as a centre of Soviet/Russian espionage 1/6
Of particular interest is the round building on the site. It is the tallest structure with an open all-round view. A perfect place for a covert #SIGINT collection point. Which it probably is. Current (2020) Google Earth images show 12 satellite dishes in various sizes 2/6
With Google Earth, you can start a time travel from 2003 to today. You can see a massive change on the roof of the building over the years. In May 2003 you can hardly see anything. In July 2006, two satellite dishes appear 3/6

The Stasi bunker in Bavaria
#thread

Unnoticed by Western intelligence services, the Stasi established a secret "Stay Behind" network in West Germany. A piece of #ColdWarHistory that has been forgotten 1/12
The "Haus am Berg" with the address Geitau 21 was a holiday guesthouse with a view of the Alps. Geitau, a tourist spot between Schliersee and Bayrischzell. But the lonely house on the mountainside had another function. It served as a secret commando bunker for the #Stasi 2/12
The location was perfectly chosen. A few hundred metres away is a field airport. Ideal for rapid troop deployments. The Austrian border is a few kilometres away. Numerous winding paths cross the green border of both states 3/12

US spy pub in Hamburg
#thread

Most people know the #Reeperbahn in Hamburg only at night. Numerous bars hide a lot of bizarre stories. A pub served as an important spy place against Poland for a U.S. intelligence agency. The pub even operated to the service 1/7
Hamburg's St. Pauli district attracts many figures - tourists, homeless people, love-seekers and sailors. And it is precisely these that various Western intelligence services are targeting during the Cold War. 2/7
Especially seamen behind the Iron Curtain are important sources of information and possible candidates for espionage in the home country. 1955, COMNAVER (US Naval Forces Germany) wrote a report on a pub: "The tavern served as a contact house for Polish agents in Hamburg" 3/7

Small service - big tasks
#thread

Luxembourg played an active role in the Cold War. For the Soviet bloc it was an important gateway for intelligence operations. The State Intelligence Service #SRE is unable to cope with its tasks. Assistance comes from abroad 1/13
Under Soviet pressure exerted since the late 1960's, Luxembourg agreed to sign an air traffic memorandum with the USSR in 1974 and a formal agreement in 1975. Shortly afterwards #Aeroflot opens a travel agency in Luxembourg city 2/13
Another service moves into the office building in 35, rue Glesener a little later. Above the travel agency the #SRE intelligence service operates a covert office. All movements at Aeroflot are monitored and registered 3/13

It was not only the US that helped #Aut to build up its signing capacities. #BND know-how was/is in great demand. The #Bundesnachrichtendienst was/is dependent on Austria for information gathering in the Balkan region 1/7
Between 1960 and 1980, the #BND was highly supportive of radio reconnaissance in particular. The espionage was of course also aimed at the Soviet presence in Austria 2/7
Cooperation culminated in the war in Yugoslavia. There were several mobile receiving stations along the Slovenian border. Austrians and Germans „shared headphones“ at that time 3/7
