Germany and the Netherlands are fascinating places to explore urban development and neighborhood change, and there may be no better place to visit than the selected cities of Berlin and Amsterdam. During WW2, Berlin was severely destroyed, leading to one of the most fascinating questions any urban student or citizen could ask, "If we were able to start all over in building our cities, what would we do differently?" Facing this challenge over the last few decades, coupled with a divided Germany (and Berlin) into East and West, has caused Berlin to go through massive transformation, at a much later time than many other European cities. During this same timeframe, Amsterdam was also facing competing forces of transformation. Once a city destined to be clogged with personal cars, Amsterdam’s residents forced a dramatic shift toward being a city center on humans instead of automobiles through direct civic engagement, setting the path to be a cycling mecca ready for a greener future.
