Scheitelhaltung, Canal structure in Sulztal, Germany.

Scheitelhaltung is a sculpture by Hannsjörg Voth consisting of two white granite walls flanking the Main-Danube Canal at the European watershed. The southern wall runs about 144 metres to the towpath and rises 14 metres there, read as a white sail; the northern wall is just under 3 metres high and 2 metres wide at its base. Both walls align along a 6 cm wide top surface that disappears into the ground at the outer ends.

The structure was designed by Hannsjörg Voth in a competition with artists Max Bill and Erich Hauser and was meant to represent the European watershed between the North Sea and Black Sea. This design combines technical function with artistic expression as part of the Main-Danube Canal system.

The name refers to the canal's summit reach, where the Main and Danube watersheds meet. The granite, quarried at Aicha vorm Wald, was stoked along the walls' long sides so tiny prisms reflect light; the faces toward the water were left rough, absorbing light so the stone seems shadowed. The southern wall's tall end is read as a white sail.

The site is easily accessible on foot and sits directly along the publicly accessible canal path near Sulztal. Visitors should be aware that boats pass at regular intervals, making it possible to observe the water movement and regulatory function in action.

The granite was quarried at Aicha vorm Wald. Its long sides were stoked, leaving tiny prisms that reflect light, while the faces turned toward the water were left rough so the coarse stone swallows light and seems covered by a large shadow.
