The Castle Drachenburg is a romantic work of art from the period of 1870 surrounded by the wonderful nature of the Siebengebirge, which is definitely worth seeing. The castle Schloss Drachenburg is one of the landmarks of the Siebengebirge. The Siebengebirge "seven mountains" is a German range of hills to the East of the Rhine, southeast of Bonn, consisting of more than 40 mountains and hills. It is located in Königswinter. It is of volcanic origin and came into being about 400 million years ago. Much of the territory covered by the Siebengebirge belongs to the Naturpark Siebengebirge, which is under environmental protection. In the fore-fortress the only “Museum for the History of Preservation of Nature” found a suitable place.
