During the 20th century, Berlin has had many faces: an imperial hub and thriving business center in the early 1900s, a chaotic yet culturally dominant mega-city during the inter-war years of the 1920s; the stage for the grisliest drama of the 20th century during the 1930s and 40s; a shattered, divided city during the Cold War; and finally the "poor but sexy" capital of a reunited and resurgent Germany.
I'll try to go into depth about each of these aspects in other posts, but for now I wanted to write a brief description of the city as I've found it.
