Marching music was playing while the crane lifted the guard house up into the Berlin sky. The foreign ministers smiled into the cameras. On June 22, 1990, they were negotiating the unification of Germany in East Berlin. The dismantling of the border was a symbolic act to end the division of Berlin for all to see. They did so at a very special border crossing, Checkpoint Charlie. This is where Allied soldiers, diplomats and foreign guests had previously crossed the border between West and East Berlin.
After reunification, the world-famous border crossing was no longer needed. A huge wasteland in the middle of the city waited for its new purpose. The Berlin Senate expected an economic and real estate boom and granted US investors an American Business Center with five large office buildings. The boom, however, never came, only three buildings were built, bankruptcies followed. Two properties remained empty, an insolvency administrator rented them out to booth owners. They earned good money due to the increasing number of tourists who continued searching for the Wall, but hardly found any traces anymore.
In November 2004, the Haus am Checkpoint Charlie, a privately run museum about the Wall and escape from the GDR, erected more than a thousand crosses in the open space. These represented the dead of the GDR border regime. They remained there until July 2005. Many press comments rejected this so-called "Freedom Memorial" as tasteless and artificial. Yet it initiated a discussion about commemorating the Wall. The unanimous opinion was that too little was being done, the memory was fading. As a result, the Senate sought new solutions and passed the "Gesamtkonzept Berliner Mauer", in English "Overall Concept Berlin Wall". It determined that a new exhibition at Checkpoint Charlie should explain the worldwide significance of the Cold War. The wastelands disappeared behind construction fences. Since 2012, there have been changing information exhibits on the Cold War and the division of Berlin.
Then the boom arrived after all, the real estate carousel took on speed again. A new investor planned a hotel on the wasteland, also offices and apartments, as well as the museum space required by the authorities. Berlin debated these plans at length. At the end of 2019, the Senate finally rejected them, including the hotel. What is certain, however, is that a museum is supposed to be built on the historic site.
