As it stood in 1588
What Burg Hollenburg looked like in its prime.
Long, low rectangular main block with two slightly projecting end pavilions under broad, grey hipped roofs; continuous ridge line and shallow roof pitches. Pale plastered stone façades punctuated by regular small rectangular windows and a few paired arched windows; a stone terrace and parapet run along the visible face. The castle sits directly on a steep rocky promontory with a stepped retaining curtain wall and dense tree cover below.
Its story
The story of Burg Hollenburg.
Swiker, Lord of Hollenburg, first appears as a witness in the 1142 foundation deed of Viktring Abbey, believed to have been a vassal of the ducal House of Sponheim; his son Reginher accompanied King Conrad III of Germany on the Second Crusade in 1147. The castle's rock on the northern slope of the Drava valley, near Köttmannsdorf in Carinthia, carried real strategic weight — it commanded a Drava river crossing and the road to the Loibl Pass and Carniola.
When the Hollenburg dynasty died out in 1246, ownership passed to the Styrian Lords of Pettau, and in 1438 the castle was inherited by the House of Stubenberg; the Friuli earthquake of 1348 had meanwhile done severe damage. In 1514 the Habsburg emperor Maximilian I, deep in debt from his war against Venice, sold Hollenburg to his son-in-law Siegmund of Dietrichstein, elevating him to the rank of Baron.
The Dietrichsteins had the castle rebuilt in Renaissance style, finished in 1588, and held it until their Hollenburg branch died out in 1861; in 1913 it was acquired by the Wittgenstein family. The long, continuous building mass with its end pavilions and terrace still stands on its rock at 561 metres above the Drava.
