The counts of Wurmbrand reinforced the castle as the Turks threatened the area.

Ongoing decay during the next 200 years almost totally destroyed the castle.

Today, the reconstruction of the medieval tower house is almost finished.

It is most likely the oldest high-rise building in Styria with a height of 32 metres (105 ft).
