The Brothers Grimm were among the 19th-century intellectuals living in the quiet villa-studded colony south of the Tiergarten, which evolved into the capital's embassy quarter in the 1920s. After WWII the obliterated area remained in a state of quiet decay while the embassies all set up in the West German capital of Bonn. After reunification, many countries rebuilt on their historic lots, accounting for some of Berlin’s boldest new architecture, which can be nicely explored on a DIY wander.
