Ruin

As it stood in 1150

What Rudelsburg looked like in its prime.

Perched on a steep, layered shell-limestone escarpment 85 metres above the Saale, the castle forms a compact plan of broad, pale-grey curtain walls enclosing a tall, square central keep with a high, pitched roof and crenellated wall-walk. To the east a rounded outer keep projects from the curtain; narrow window slits and small rectangular openings pierce the masonry. The rocky cliff falls away directly beneath the walls; wooded slopes and fields spread below.

Its story

The story of Rudelsburg.

The Rudelsburg was established in 1050 as a border fortification by the Bishop of Naumburg, securing trade routes such as the Via Regia through the Saale valley, and was extended around 1150 with central and outer wards. It became a point of conflict between the bishops of Naumburg and the Margraves of Meissen of the House of Wettin; Margrave Heinrich III received the castle from the bishop in 1238 as recompense for services to the church and installed families of the service nobility there.

The Schenk family of Saaleck, of the House of Vargula, are named as masters of the citadel in 1383, and a Wettin loan certificate of 1441 records the brothers Rudolf, Günther and Heinrich von Bünau as owners, apparently holding no land beyond that on which the castle stood. In 1581 the von Bünaus sold the Rudelsburg to Hans Georg von Osterhausen to cover their debts. The castle was destroyed in the Thirty Years' War and fell into disrepair.

The ruin, a Romanesque bergfried some 20 metres high under its stone pyramid roof, with a great hall and encircling walls above the cliff over the Saale, became a popular destination in the early 19th century with the romanticisation of mountains and the rise of hiking. From 1855 it achieved national renown as the annual meeting place of the Kösener Senioren-Convents-Verband, the oldest union of German-speaking student fraternities.
