Osterburg, Medieval castle ruin in Haunoldstein, Austria.
The remaining structures of Osterburg include a Romanesque round tower, segments of the kennel wall, and portions of an outer bailey.
The castle originated around 1175 and functioned as a strategic defensive structure in the Wienerwald region until its gradual decline.
The ruins demonstrate medieval Austrian architectural methods through the preserved stone walls and construction techniques from the Romanesque period.
Located at coordinates 48.20525, 15.44107, the ruin allows visitors to explore the grounds and examine the remaining fortification elements.
The round tower foundation reveals engineering methods used in early medieval Austrian castle construction, particularly in stone placement patterns.
