Over the summer months, Michael Hischer's kinetic large-scale sculptures turn the citadel into an outdoor art space. 20 works from a multi-year cycle will be shown.
They are designed for the outside space, the wind moves them and allows them to be recognized as kinetic sculptures. The movement of its elements is left to chance due to the weather. In this way, time is inscribed in the sculptures and not only made tangible as four-dimensional objects.
