Burgruine Arbesbach, known locally as the 'Stockzahn' of the Waldviertel, rises dramatically from a granite cliff at 900 meters elevation as one of the region's most distinctive castle ruins. Built in the late 12th century by Hadmar II von Kuenring as an outpost against northern Slavic territories, this medieval stronghold served as a crucial border guardian. After a destructive 1480 Bohemian raid left it permanently damaged, the 25-meter remnant tower was converted into the Alexanderwarte viewing platform, rewarding visitors with panoramic vistas stretching from Bohemia to the Alps. Its isolated hilltop location and commanding presence make it an iconic landmark and popular hiking destination.
