Absolutely amazing observatory! They have a lot of public tours, and if the weather cooperates, you can even observe through the gigantic telescope yourself! On the top they also have a small cafe and an observation deck for the city view. Magnificent!

Beautiful experience, something you really don't do everyday. Unfortunately, the tour was in German only. You also have to be lucky with the weather, as clouds can obscure the sky. However the view from the top is very cool

We had a private tour and were just amazed. The tour guide was fantastic, super enthusiastic about the observatorium, the stars and everything. We had many questions and he had an answer to all of them. He had his repertoire but was more than willing to adjust to all our requests. The only downside was that after an hour the clouds blocked our view into the sky. But even for that he had a plan B to demonstrate us the capabilities of the telescope.
