Schloss Weißenau, Wolfsberg, Renaissance castle in Wolfsberg, Austria

Schloss Weißenau is a Renaissance castle in Wolfsberg featuring a two-story structure with three wings arranged around a central courtyard. The building combines architectural elements from the 16th and 17th centuries.

Andreas Weiß, Pfleger at Burg Twimberg around 1517, had the castle built at the start of the 16th century. From 1683 to 1687 it belonged to Franz Caspar von Stadion, Bishop of Lavant. In 1856 Hugo Graf Henckel von Donnersmarck acquired it, and from 1890 his widow Laura von Kaszonyi had it remodelled in romantic historicism; since 1919 it has belonged to the Thun-Hohenstein family.

The Festsaal in the southwest wing keeps baroque stucco on its ceiling and fireplace; the mantel carries the coat of arms of Franz Caspar von Stadion, Bishop of Lavant, who held the castle from 1683 to 1687. The upper-floor chapel in the northeast wing was fitted out around 1890 in uniform neo-Gothic forms and retains its original interior.

The castle is located at Reinfelsdorf 20 in Wolfsberg and is easy to find from the main road. Keep in mind that this is a protected historical monument and may have limited public access depending on current conditions.

The east tower's crenellations and the Tudor Gothic facade date from Laura von Kaszonyi's remodelling after 1890, when the tower and library were also built and the northeast wing renewed. The core of the three-winged courtyard building is older, from the 16th and 17th centuries.
