Ruinenberg by bugulma
In the courtyard of Sanssouci, from place near of entrance, you can enjoy view to Ruinenberg, that is situated on the hill, just in front of Sanssouci Palace. It is water reservoir place for fountains in the park. Besides there are artificial ruins around and that was the reason to get such name to the place. It was built in 1748.
