Singular situation in the municipality Nierstein in the German cultivation area Rheinhessen. It was already mentioned in a deed of donation in 742 and is therefore considered the oldest vineyard site in Germany. It is said that the ringing of a church over the vineyard inspired the name. In 1141 it was mentioned as "Clegken". The south-facing vineyard at an altitude of 90 to 130 metres above sea level with a slope gradient of 5 to 15% comprises only 2.11 hectares of vines, which have been completely enclosed by a wall since 1761. The soils consist of loess on red clay slate (Rotliegend) with sandy loam and have an excellent water retention capacity. Riesling andPinot Noir are cultivated here. The site has been the sole property of the Staatliche Weinbaudomäne Oppenheim (predecessor of the Hessian Wine Estate) since 1925.
