The Castle Hochosterwitz was built on a limestone rock that rises 150m above the valley and allows the visitor a spectacular view over the neighbouring mountains, hills and countryside.
The castle was first mentioned in 860. It was a refuge for the local population during the Turkish invasion in the 11th and 12th century. After the death of Hans Schenk von Osterwitz, the last owner of the original lien, the castle was returned to King Friedrich III.
In gratitude for the support of the imperial troops during the wars against the Turks the lien of thecastle Hochosterwitz was given to Christoph Khevenhüller von Aichelberg by Kaiser Ferdinand I in 1541. Christoph Khevenhüller started to rebuild the castle according to the plans of one of the greatest military architects of that time: Domenico dell’Aglio.
Georg Khevenhüller extended the buildings to their actual size using his own private money. In the castle yard a marble memorial tablet dated 1576 proclaims that Georg Khevenhüller had „reconstructed this castle with his personal means. It being his home, he surrounded it with walls and fitted out with bastions and an arsenal“.
Since then the Castle Hochosterwitz has been owned by the same family for generations.
Many centuries have passed, but castle Hochosterwitz has not changed – only its purpose became a different one. Luckily, there was always some member of the family who, remembering the warning carved in stone by his ancestor, made great sacrifices to maintain the castle in good condition.
