Burgruine Haichenbach, also known as Kerschbaumer Schlössl, first appeared in documents in 1160 when brothers Otto and Wernher von Eichenbach held the fortification. Perched 450 meters above sea level on a mountain ridge creating the dramatic Schlögener loop of the Danube, the castle gradually fell into ruin after 1529. Today the atmospheric ruins have been converted into a scenic viewing platform offering breathtaking panoramic vistas across the Danube Valley and surrounding Alpine landscape, attracting hikers and nature enthusiasts exploring the region's dramatic topography.
