Burg Greifenstein is 227 metres (745 ft) above sea level.
It began life playing a significant role in the defense system along the Danube.
More recently, in the 16th century, the castle served primarily as a notorious prison of the ecclesiastical court.
Johann I von Liechtenstein refurbished it in 1807–08 in the Romantic style but at the end of the 19th century, the castle fell again and was sold in 1918, coming into private ownership.
