Several times occurring single site designation in Germany, which refers to a possibly no longer existing fortification.
It owes its name to the castle complex that the German King Philip of Swabia (1177-1208) had built as his imperial seat. It lies on a former volcanic cone below the single vineyard landskrone. The vineyards, which are oriented from southwest to southeast, at an altitude of 80 to 200 metres above sea level with a slope of up to 50%, cover almost 15 hectares of vineyards. The soils consist of greywacke, greywacke slate, loess, loess loam and hanging loam, as well as basalt in the upper areas. The varieties cultivated here are mainly Pinot Noir, Domina and Riesling. The producers Adeneuer, Ahr Winzer eG, Bertram Julia, Burggarten, Maibachfarm, Meyer-Näkel and Nelles Thomas, for example, have shares in the site.
