The downtown cityscape of Cologne is the result of the conscious decision to connect old and modern architecture. After the destruction of the town during the Second World War, which left 90 percent of Cologne’s historic center in ruins, Cologne’s politicians and city planners agreed upon reconstructing and preserving buildings and monuments which are decisive for its 2000-year history and character, while taking a leap into the future at the same time.
The result is as a curious mix of styles. On the basis of the historic rubble and debris, a city was formed out of steel, concrete and glass. Therefore, it is dominated by strong dualisms, which may complement or contrast each other.
