Two buildings by architect Karl Heinz Schwarze in Bochum provide a special view of the sky: In addition to the observatory in Weitmar, the employee of the municipal planning office also designed the planetarium on Castroper Strasse, which is still one of the most modern planetariums in the world today. The large Zeiss projector faithfully reproduces astronomical processes.
The parabolic dome shell of reinforced concrete, clad in stainless steel and supported on three points, extends over a hill. Under this outer shell is a plastic-coated aluminium dome with a diameter of 20 metres. The foyer, whose facade elements are glazed, is arranged around the central demonstration hall. In a side wing there are rooms for administration and seminars.
