The subway station at Fehrbelliner Platz is located in the district of Charlottenburg-Wilmersdorf, on the crossing of U3 and U7 lines.

It was built in 1913 as one of the original U3 stations. At the beginning it was only an underground station, decorated in Jugendstil style. The Pop Art retro-futuristic building we can see today came into existance as a part of the extension on the U7 line. It was designed by Rainer G. Rümmler. The station was built between 1968 and 1972.
It’s postmodern style was a part of a broader architectural movement in Berlin at the time. You can read more information about the architecture of the times on the Berlinische Galerie Website here: http://www.berlinischegalerie.de/ausstellungen-berlin/rueckblick/2015/radikal-modern/
The station’S style is mostly achieved through the usage of mostly round shapes, various colors and materials. It’s mostly covered in red tiles, with green concrete and steel elements and yellow cylinder lamps.
