Schloss Drachenburg is sort of a fairytale castle built in the late 19th century. If you climb up to Drachenfels by foot, you can take a rest here and stroll through the park gardens. In the castle you'll find a small exhibition on the castle's history
Schloss Drachenburg or Drachenburg Castle is a private villa styled as a palace and 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 east bank of the Rhine, south of the city of Bonn. Baron Stephan von Sarter (1833–1902), a broker and banker, planned to live there, but never did.

'Drachenfels' is a Magma outcrop in Königswinter where, according to legend, Siegfried slayed the dragon that lived on the mountain. Have a coffee there and enjoy the nice view down to the Rhine valley.
