Three to One

The glass stairwell of the AOK building, with its elegant spiral staircase, was the centerpiece of documenta 9 in 1992. American artist Max Neuhaus created the sound installation *Three to One* specifically for this location: Without any visible interventions, Neuhaus transforms the space into a meditative sound space that changes in response to the movements of visitors. In this way, space and time, interior and exterior, city and landscape intertwine in a new sensory experience of space.
