This is probably one of my favourite buidings ever, it's completely bonkers.
The Bierpinsel (Beer Brush opened on the 13th of October 1976 as the Turmrestaurant Steglitz. It was built between 1972 and 1976 by architects Ralf Schüler and his wife Ursulina Schüler-Witte in the Pop Art style. Due to it's unusual shape it's had a bit of a rough time and has changed owners way too many times but thankfully since 2017 it is now a listed building.
Pictures were taken in March 2019.
