Rudelsburg

The Rudelsburg is a ruined hill castle located on the east bank of the river Saale above Saaleck, a village in the borough of Naumburg in the county of Burgenlandkreis in Saxony-Anhalt, Germany. The Rudelsburg was built in the Middle Ages by the Bishop of Naumburg and served to secure trade routes such as the Via Regia through the Saale Valley.

The Rudelsburg was a point of conflict between the bishops of Naumburg and the Margraves of Meissen belonging to the House of Wettin. The castle occasionally served various noble families as a residence, until it was destroyed in the Thirty Years' War and thereafter fell into disrepair. In the early 19th century the Rudelsburg became a popular tourist destination thanks to the romanticisation of mountains and the rise of hiking as a pastime.
