Castle ruin Klamm

Castle ruin Klamm consists of stone walls and fragments from a medieval fortress positioned on elevated ground in the Klamm gorge near Neunkirchen. The location provides views across the surrounding valley and Lower Austrian landscape.

Written records from 1130 first mention Ortolfus de Clamma as an early resident of this strategic location. The fortress later came under the control of Emperor Maximilian I after military campaigns in the region.

The name Klamm refers to the narrow gorge surrounding the ruins, showing how medieval fortifications were built in harmony with the landscape. Visible stone walls and structures today reveal how the inhabitants adapted to life on elevated terrain.

The ruins are accessible on foot from Breitenstein, though no direct vehicle access reaches the site itself. Sturdy footwear is recommended as the paths are uneven and the hilltop location is exposed to weather.

The fortress changed hands multiple times throughout its existence before gradually falling into decline and becoming the fragmentary ruins visible today. This slow deterioration gives the site its current character and appearance.
