Burg Hausenbach, Medieval castle in Karlstetten, Austria.

Burg Hausenbach is a medieval castle built on a granite rock formation and composed of a two-story palace with Romanesque features. The high defensive tower of the structure represents the original fortification and contributes to its distinctive shape.

The castle originates from the 13th century and is first documented in 1237 under the rule of Weichard I von Doppel. This record shows its early roots as a noble property in the region.

The gate tower of the outer bailey carries painted coats of arms of the Jörger and Zinzendorf families above its arched passage, recalling the owners who held the castle between 1515 and 1657. The passage still shows where the drawbridge once crossed the moat, which is now filled in.

The castle remains in private ownership and interior spaces are not open to the public throughout the year. You can view the structure and its details from the surrounding area without entering the property.

The core castle consists of a massive two-storey palas and a tall square keep, both built simultaneously in the 13th century in Romanesque style. The keep's six storeys are topped by a bent pyramid roof, and its lower windows were only broken out later. The palas later served as a granary, which is why its interior was almost completely gutted.
