Berlin is something of an upstart in the world of European capitals. As a city, it didn’t really get going until the 19th century. But then it took off in style – especially with regard to its architecture. In just a few years, the home of the Hohenzollern family had developed into a major conurbation with more than a million inhabitants. But Berlin is a city in flux. A "new" Berlin has clearly emerged since the fall of the Berlin Wall, but the city is still constantly evolving.
