single vineyard in the municipality of Nierstein in the German wine-growing region of Rheinhessen. It was mentioned in a deed of donation as early as 742 and is therefore considered the oldest vineyard site in Germany. Supposedly, the ringing of the church bells 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 of 5 to 15% covers 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 and Pinot Noir are cultivated here. The site has been the sole property of the Oppenheim State Vineyard Domain (predecessor of the Hessian Vineyard Domain) since 1925.
