Schloss Drachenburg looks like a medieval castle, but it is a private villa built in just a few years in the 1880s on the slope of the Drachenfels in Königswinter, across the Rhine and a little upstream from Bonn. It was commissioned by Stephan von Sarter, a Bonn-born stockbroker who made his fortune in Paris, and he never actually lived in it.
Schloss Drachenburg at a glance
- Where: on a terrace on the north-west slope of the Drachenfels in Königswinter, about 150 metres above the Rhine, next to the middle station of the Drachenfels Railway.
- Built: 1882 to 1884, in a mix of Gothic Revival and Renaissance Revival styles.
- By: the Düsseldorf architects Bernhard Tüshaus and Leo von Abbema, with Wilhelm Hoffmann, who added the art hall and the north tower.
- What it is today: a museum of 19th-century upper-class living run by the North Rhine-Westphalia Foundation, with a landscape park and, in the outer bailey, a museum on the history of nature conservation.
- Time needed: one and a half to two hours for the rooms and the park; half a day if you continue to the top of the Drachenfels.
From a baron's showpiece to a rescued monument
Sarter came from a modest Bonn family, trained at the Sal. Oppenheim bank and made a fortune speculating on the Paris stock exchange. In 1881 he was made a baron, and he wanted a residence fit for the title, within sight of his home town. He stayed in Paris, rarely came, and died unmarried in 1902. His coat of arms with the motto 'Wäge und wage!' (weigh up and dare) can still be seen in the castle.
After his death the building went through many lives: a tourist attraction run by his nephew, a Catholic boarding school, a Nazi elite school during the Second World War and a railway training centre until 1959. Then it stood empty and decayed; demolition was even considered. A textile merchant, Paul Spinat, bought it in 1971 and opened it to visitors. The state of North Rhine-Westphalia acquired it in 1989, and a restoration of more than 15 years brought the rooms back in 2010, with the park following in 2011.
What to look for
- The main staircase, lined with large history paintings of emperors and Rhineland scenes; only some of the original series survived.
- The Nibelung Room, decorated with scenes from the Nibelung saga, the legend most closely tied to the Drachenfels.
- The art hall, a long vaulted room with an octagonal dome that was rebuilt during the restoration.
- The north tower, about 30 metres high, which gives the castle its fairy-tale outline when you see it from the Rhine.
- The Venus Terrace in the park, with its gilded deer and a lion fountain, and the view over the Rhine valley towards Bonn.
Dragons, legends and a TV villa
The Drachenfels, the 'dragon's rock', owes its name to old stories, and local tradition claims it as the place where Siegfried, hero of the Nibelung saga, killed the dragon. That is legend, not history, but Sarter's decorators made the most of it. More recently, the castle appeared in the German TV series Babylon Berlin as the home of the industrialist Alfred Nyssen.
Tips for your visit
- Come on a weekday morning if you can; the Drachenfels draws big crowds at weekends.
- Ride the Drachenfels Railway to the middle stop, or walk up the steep Eselsweg from Königswinter's old town and take the train back down.
- The best photo of the castle is from below, on the path up from Königswinter, where its towers stand out against the hillside.
Nearby
- Drachenfels summit: the ruins of a 12th-century castle and a wide view over the Rhine and the Siebengebirge hills, a short but steep climb above the castle.
- Drachenfels Railway: a rack railway opened in 1883, the most comfortable way up the hill.
- Nibelungenhalle: a temple-like hall built in 1913 for the centenary of Richard Wagner's birth, with paintings of his Ring operas, on the path to the summit.
- Königswinter old town and Rhine promenade: cafés and boat landings at the foot of the hill.
