One goes to London to see and learn about things that are old - the history, the architecture, religion, etc.. In Berlin, it's alll about the new: New architecture, art, fashion, attitudes. An aura of individualism, youth and cutting edge ideas imbues the city like exotic spices infuse food from the vibrant Turkish quarter of this extraordinarily international town.
This town is full of museums, restaurants, monuments and other touristy spots, but one is most impressed, perhaps, by the city itself - the cosmopolitan crowds, the cutting-edge architecture, and the huge areas of green space everywhere. It's flat as a skillet and perfect for bicycle riding - particularly compared to hilly Austin where biking is great for bulking up your calves but not really a viable way for average people to get around when the weather's hot. While we've been here (in late August and early September) the high temperatures have been in the 60s - a little cold for Kathy but right in my wheelhouse.
Word War II and the Cold War left a scar on this town's psyche which in many ways still defines the city, if only by what its denizens are AGAINST (which typically defines people much more than what they are FOR.) There's a disdain for conformity and a celebration of diversity and individualism that's striking and rather extreme, even coming from the United States which of course fancies itself the global bastion of individualism. On that score, though, Berlin's got us beat by a country mile. I think it's because the last 20 years in the city have been defined by a reaction against East German/Stasi authoritarism. The folks who brought down the Berlin Wall - and most especially their children, who have never lived under dictatorship - have embraced the "Never Again" slogan, which European Jewry adopted after World War II when establishing Israel, and are building a new Germany here whose values and approach to living is antithetical to Nazi and Communist totalitarian rule. That's an impression from a visitor, not a learned historical analysis, but it's difficult to otherwise explain the vibrant dynamism we've witnessed in every corner of the city we've visited..
I really like this town. Kathy suggested I might like to come and live here for a while, and (as usual) she's probably right.
