"A mountain on the north bank of the River Rhine near Mainz has been associated with the Church and with winemaking since the Dark Ages, when Ludwig der Fromme (\"Louis the Pious\") made 6000 litres of wine during the reign of Charlemagne. In 1100, Benedictine monks completed a monastery on the Bischofsberg (\"Bishop's\") mountain, having identified the site as one of the best places to grow vines. 30 years later they built a Romanesque basilica in honour of John the Baptist, and the hill became known as Johannisberg (John's mountain). It was constructed according to similar floor plans as its mother house,St. Alban's Abbey, Mainz. As such the monastery was a prime target for the Anabaptists in the Peasants' War of 1525, and it was destroyed. In 1716 Konstantin von Buttlar, Prince-Abbot of Fulda, bought the estate from Lothar Franz von Sch\u00F6nborn, started construction of the baroque palace, and in 1720 planted Riesling vines, making it the oldest Riesling vineyard in the world. The estate changed hands several times during the Napoleonic Wars, but in 1816 the Holy Roman Emperor, Francis II, gifted it to the great Austrian statesman Prince von Metternich. The estate remains in the hands of the Oetker family today. The buildings were almost completely destroyed by air raids on Mainz in 1942, and after the war took twenty years to reconstruct. There are currently about hectares ( acres) of vineyard."@en . . . . . . "Schloss Johannisberg"@en . .
