The Brandenburg Gate, seen in times of war and peace. The Kaiser Wilhelm memorial, once towering over a large square, is now long gone. The Berlin Wall, an icon of a divided city, now not much more than memory. The images of Berlin's history tell a story that moves from prosperity to chaos, ruin to restriction, before returning once again to stability and confidence.In Berlin Then and Now, vintage black-and-white photographs from throughout the life of the city are seen next to amazing color photos of Germany's capital today. From the Charlottenburg Palace, more than two-thirds destroyed in World War II but lovingly restored today, to the Kroll Opera House, a luxurious building once used as a temporary hospital during wartime and whose site is now a beautiful park, the city's most remarkable sites show why Berlin has long fascinated historians and tourists alike.
