Burg Ottenstein, Medieval castle in Rastenfeld, Austria.
Burg Ottenstein is a granite castle built on a rocky spur above the Ottenstein reservoir in the Waldviertel region of Austria. The complex includes several towers, thick defensive walls, and a small chapel inside the fortified enclosure.
The castle was built in the 12th century to control the trade route along the Kamp River. Over time it shifted from a military stronghold into a residential seat for the local nobility.
The castle is used today as an event venue and draws visitors who want to see medieval architecture up close. The chapel inside the walls is a quiet reminder of the religious life of its former residents and can sometimes be visited.
The castle is often booked for private events, so it is worth checking ahead before planning a visit. Those who cannot enter can still get a good view of the fortifications from the shore of the reservoir below.
A wine cellar was carved directly into the granite rock beneath the castle, using the natural coolness of the stone to store regional wines. This underground chamber is still part of the working life of the property during events.
