Note that one of the photos presented is from <i>West</i> Berlin, Germany, and of the former NSA Echelon listening station:<p>&quot;Teufelsberg Spy Station, Germany. ... in Soviet Ghosts&quot; ?!<p><a href="https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Teufelsberg" rel="nofollow">https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Teufelsberg</a><p>&quot;The US National Security Agency (NSA) built one of its largest listening stations atop the hill, rumored to be part of the global ECHELON intelligence gathering network. &quot;The Hill&quot;, as it was known colloquially by the many American soldiers who worked there around the clock and who commuted there from their quarters in the American Sector, was located in the British Sector. In July 1961, Mobile Allied listening units began operations on Teufelsberg,[4][7] having surveyed various other locales throughout West Berlin in a search for the best vantage point for listening to Soviet, East German, and other Warsaw Pact nations military traffic.&quot;<p>&quot;In the 1990s, as Berlin experienced an economic boom after German reunification, a group of investors bought the former listening station area from the City of Berlin with the intention to build hotels and apartments.&quot; (for less than 3 million USD(!) - Ed.) &quot;There was talk of preserving the listening station as a spy museum. Berlin&#x27;s building boom produced a glut of buildings, however, and the Teufelsberg project became unprofitable. As of the early 2000s, there has been talk of the city buying back the hill. However, this is unlikely, as the area is encumbered with a mortgage of nearly 50 million dollars.&quot;
