This neo-Baroque edifice housing the German Bundestag (Parliament) survived wars, Nazis, fire, bombing and the country’s division, only to return as a symbol of a new era in German politics. A trip to the top of this open, playful and defiantly democratic space, designed by Sir Norman Foster, is a must, but note that you can’t just rock up anymore: you must now book in advance by filling in an online form at visite.bundestag.de, at least three working days in advance.
