Unfortunately, in the haste to destroy all traces of the former East Germany, many Cold War relics have disappeared. Paved over, rebuilt upon--at the moment, Berlin is the largest construction site in Europe, possibly the world, as its Eastern half is revitalized. But there are still remnants left, if you know where to look. So for the Cold War aficionado, or the just plain curious, or those who were too young to remember the heady days of Khrushchev vs. Kennedy and want to really know what it was all about, this is the city to begin.
The Cold War began in 1945, before the ashes of World War II had even cooled. The victorious powers met at Potsdam, a city on the outskirts of Berlin, and negotiated the Potsdam Treaty, dividing Germany into four zones of occupation. The treaty was signed at the Schloss Cecilienhof, which stands in the midst of the Neuer Garten, a park located on the western banks of the Heiligensee. Today the Schloss Cecilienhof is a luxury hotel, and you can see the room where the treaty was signed.
Berlin was a special case. The capitol of the Third Reich, once one of Europe's great cities, had been reduced to a heap of rubble. But because it lay in the East, in the Russian occupation zone, it rightfully should have come under full Russian rule. However, that did not sit well with the Allies, who hesitated to give the Soviets complete control of such an important city. Berlin was divided into four occupation zones of its own--the U.S., Great Britain and France in the West, and the Russians in the East.
