Mercedes-Haus, Frankfurt am Main

The Mercedes showroom on Kaiserplatz became symbolic of the 1950s economical miracle in Germany. Frankfurt's most notorious prostitute, Rosemarie Nitribitt, used to park her Merc here before crossing the road to pick up clients in the Frankfurter Hof Hotel opposite. Even today, the semi-circular glass facade is an outstanding example of classical modernism. The showroom has recently undergone major renevation work and has been brought in line with 21st century tastes. If you haven't got enough cash to buy the latest Mercedes, maybe you could manage to splash out on one of the baseball caps, umbrellas or scarves sold here.
