Besides the hiking trails and scenic viewpoints, the medieval castle ruins are exciting places to see in the Siebengebirge. You can visit three of them in one day – Drachenfels, Löwenburg and Rosenau. Yes, the mountains and the medieval castles have the same name, that’s a bit confusing. Moreover, there is Reitersdorf Castle in Bad Honnef on the bank of river Rhine, at the foot of the Siebengebirge.
Today, the castle ruins are tourist attractions, and it is a bit difficult to imagine the Siebengebirge in the Middle Ages when these castles were built: dense forests all around, dirt tracks rather than broad trails for pedestrians, riders and carriages, fogs, no lights and no inns. It must have been intimidating, especially on foggy days.
In the High Middle Ages a little castle stood here for a short time, but only little is known about it. Obviously it was built in great haste within a few years. Since 1222 Dietrich of Dorndorf, a lower aristocrat, called himself Dietrich Count of Rosenau. He died in 1243, and still in the same year his family sold the castle Rosenau to the nearby Monastery of Heisterbach, just to be torn down around 1250. The motives for that have remained in the dark until today.
Unfortunately, nothing has been remained of the medieval castle on top of Mount Wolkenburg.
