Greifenstein Castle

The castle was probably built in the 11th century by the landlord, the diocese of Passau. It is possible, however, that an observation tower stood on this striking point in the area as early as Roman times.
The castle was an important link in the defense system on the Danube. Their chalk fire station made it possible to exchange messages with both Kreuzenstein and Leopoldsberg.
It was first mentioned in a document in 1135. The then named Dietrich von Greifenstein was probably a servant of the Passau bishops. In 1247, Bishop Rüdiger von Bergheim had the facility greatly expanded. In 1365 the castle was besieged by the citizens of Klosterneuburg for unknown reasons. It is certain that Greifenstein belonged to the Hungarian sphere of influence from 1485 to 1490. When the Turks succeeded in taking the practically undefended castle in 1529, the valuable archive was destroyed. It was then renewed, but no longer had any military significance.
From around 1600 the

Greifenstein Castle is a hilltop castle built in the 10th century that is quite well preserved. It is one of those castles in today's Lower Austria around which many legends have been formed.
