Burgruine Kammerstein

Burgruine Kammerstein is a medieval castle ruin in Perchtoldsdorf with walls still reaching heights of around 15 meters. The structure shows a compact layout featuring a pentagonal keep with thick walls that once served as the main defensive strongpoint.

Otto II von Perchtoldsdorf built the castle between 1240 and 1250 after his previous residence was destroyed during local uprisings. The fortress represented a fresh start for his family during a period of territorial conflict in the region.

The name Kammerstein comes from Otto II, who held the position of chamberlain of Austria and connected the castle to his administrative role. The ruins today stand as a physical reminder of how medieval power was tied to specific titles and territories in this region.

The ruins can be reached via a marked hiking trail starting from the parking area at Kaltenleutgebner Straße 141, requiring about 20 minutes of walking. The path climbs uphill, so sturdy footwear and a reasonable level of fitness are helpful for the visit.

The pentagonal keep featured three-meter-thick walls and could only be entered by ladder, demonstrating an unusual defensive strategy for its time. This deliberate design choice made the tower significantly harder to breach during medieval siege attempts.
