IMMEDIATELY UPON ITS completion in 1970, Berlin’s Haus der Statistik (which stood north of Alexanderplatz in the shadow of the just-built Fernsehturm) took its place as one of the central organs of the GDR state apparatus. With the collection of data and statistics for all of East Germany as its goal, the eleven-story complex housed numerous bureaucratic units, including several floors of Stasi offices. Its street-level businesses were the ultimate in urbane GDR style, hosting two lounges (Jagdklause and the fabulously named Mocca-Eck), a hunting/fishing shop, and Natascha, a boutique offering the latest Soviet imports.
