This was also at the Newseum. The plain white wall was the East Berlin side. They kept it whitewashed so they could find people with the spotlights as they tried to escape. The other? West Berlin, very colorful and vibrant - in spite of being graffitti! And the tower? That was where they shot from if they caught you trying to get over the wall.......... You could step inside the tower and they had the sirens playing, creepy. Reminded me of the Holocaust museum - very sobering.
