The castle was probably built in the 11th century by the feudal lord, the Bishopric of Passau. However, it is possible that a watchtower already stood on this prominent terrain point during Roman times.[1][2][3] The castle was an important link in the defence system on the Danube. Its beacon station enabled the exchange of messages with both Kreuzenstein and Leopoldsberg.

From this vantage point, there is a sweeping view of Greifenstein Castle, which sits elevated above the Danube backwater and dominates the landscape. The castle forms a striking historical landmark within the surrounding countryside and is clearly visible from the cycle path. Greifenstein Castle is a medieval hilltop castle in Lower Austria. It was probably built in the 11th century and was first documented in 1135. Over the course of its history, it has served various functions, including as part of the defensive system along the Danube and, at times, as a prison for the ecclesiastical court.

Greifenstein Castle sits impressively above the Danube and is a prominent landmark along many biking and hiking trails. From the viewpoints around the castle, you can enjoy fantastic views of the river, the riparian forests, and the towns on the opposite bank. It's a particularly good spot for a short detour or rest stop, especially for mountain bikers, who can combine a rewarding break with panoramic views.

You pass this great castle if you walk the Great Tullnerfeld Circular Trail 475, although you are already in the Vienna Woods :-)

Nice place to jump into the water, well paved, but very narrow in places. Drive carefully!
