Schloß Buchberg rises majestically from a rocky crest three kilometres south of Gars am Kamp on the river's right bank in Lower Austria. The fortified residence, documented from 1140-1170, underwent early 17th-century Baroque transformation under Hans Ludwig von Kuefstein, gaining approximately 40 chambers, a castle chapel, ornamental gardens, and innovative water systems while preserving its medieval core. Since 1979, the castle has served as Kunstraum Buchberg, a contemporary art space established by Dr. Dieter Bogner within the castle's historic rooms, blending cultural programming with heritage preservation in the scenic Kamptal region.
