Schloss Drachenburg is a private villa in palace style constructed in the late 19th century. It was completed in only two years (1882–84) on the Drachenfels hill in Königswinter, a German town on the Rhine near the city of Bonn. Baron Stephan von Sarter (1833–1902), a broker and banker, planned to live there, but never did. Today the Palace is in the possession of the State Foundation of North Rhine-Westphalia. It is served by an intermediate station on the Drachenfels Railway.
