Grafenegg Castle Park open-air pavilion, Grafenegg

The so-called "Cloud Tower" is located in the Grafenegg Castle Park. During the summer festival season, it is used as a stage. At other times, it is a popular destination for sight-seers. It is seamlessly integrated into the garden landscape and displays topographical features reflecting its main characteristics. It plays with perspectives and points of view, with nearness and distance, with closure and openness.
