The photographer Udo Hesse showed 20 large-format black-and-white portraits of famous architects at the petrol station Projektraum on June 2, 2019. Some of them have also realized their art in Chemnitz.

The exhibition was the harbinger of the Day of Architecture on 29 June, which also included readings and a symposium.

The gas station Projektraum is a joint art project by physicist Christian von Borczyskowski, artist Rolf Lieberknecht and photographer Ulf Dahl, which they realized in 2018. The gas station, which is a listed building, is located at the corner of Zwickauer Strasse and Guerickestrasse.
