Burgruine Zeiselberg

Burgruine Zeiselberg is a castle ruin in Magdalensberg featuring a rectangular residential tower positioned at the summit and sturdy wall segments on the northern and western faces. The fortification spans approximately 640 square meters and retains substantial remains of its original medieval construction.

The castle was built around 1250 by Albert, son of Hainricus Ziesel, as a fortified stronghold in the region. Destruction came in May 1293, after which the castle was never rebuilt.

Archaeological excavations started in 1989 revealed elements of medieval fortification techniques, providing insights into defensive architecture from the 13th century.

The ruin sits at 570 meters elevation and is reached via accessible walking paths that let visitors explore the fortification walls up close. The trails provide direct access to the main structures with clear sightlines throughout the site.

The residential tower contains specific architectural elements that demonstrate the transition period between the High Middle Ages and Late Middle Ages.
