A vineyard or site in the municipality of Dürnstein in the Lower Austrian wine-growing region of Wachau. It is located between the municipalities of Dürnstein and Weißenkirchen between the Buschenberg and Liebenberg vineyards. According to an unverifiable legend, the name goes back to Emperor Charlemagne (742-814), who is said to have camped here with the Frankish army. However, a family name is probably the origin of this designation.
The steeply terraced vineyards facing south to south-east at an altitude of 203 to 376 metres above sea level have a slope of up to 73% (36°) and comprise 15 hectares of vineyards. The southeastern part of the Kaiserberg is formed by the Lichtensteinerin sub-grove. The steeply terraced vineyards facing south to south-east at an altitude of 207 to 302 metres above sea level have a slope of up to 66% and comprise five hectares of vineyards. The poor soils consist of paragneiss and granite weathering. Here, mainly the varieties Grüner Veltliner and Riesling are cultivated. The producers Domäne Wachau, Pomaßl and Prager, for example, have shares in the vineyard.
