The castle or fortification was probably not built until the era of Turkish intrusions. It is mentioned as Studenitz castrum and later in 1542 as a tower. In 1681 the fortification was still preserved which is evident from Vischer's copper engraving whilst in 1830 Kaiser already paited it as ruins. It was probably abandoned after the fire on 7^th March 1788, which reduced to ashes whole village and the fortification, therefore only 6 years after the monastery has been dismissed at the time of Joseph II.
On Vischer's depiction the fortification is presented as serried multi-storey composition with a leaning tower which is one storey higher than the rest of the fortification. All of the buildings are surrounded by a wooden hoarding and on two corners reinforced by two defence nests.
