Johannisberg is a village in Hessen, Germany. It is part of the city of Geisenheim in the Rheingau, on the right bank of the Rhine, 6 m. S. of Rüdesheim by railway.
The place is mainly celebrated for the beautiful castle, Schloss Johannisberg, which crowns a hill overlooking the Rhine valley, and is surrounded by vineyards yielding the famous Johannisberger wine. The Schloss, built in 1757-1759 by the abbots of Fulda on the site of a Benedictine monastery founded in 1090, was bestowed, in 1808, by Napoleon upon Marshal Kellermann. In 1816 it was given by Francis I of Austria, to Prince Metternich, in recognition of his services as Austrian Foreign Minister.
