Schloss Hollenburg, also known as Burg Hollenburg (Slovene: Humberk), is a medieval hill castle situated on a steep rocky outcrop at 561 meters above sea level, overlooking the Drava River in the Rosental valley near Köttmannsdorf, Carinthia, Austria. Dating back to the 12th century and possibly succeeding an ancient cave fortress, it is one of Carinthia's most significant and aesthetically impressive castles, serving as a cultural cornerstone of the Carnica-Region Rosental. The castle blends rugged medieval defenses with elegant Renaissance additions, featuring a fortress-like exterior that conceals a festive inner courtyard. Privately owned by the Kyrle family since the mid-20th century, it is primarily an exclusive venue for events such as weddings, seminars, and celebrations, offering breathtaking views of the Drava valley, Rosental, and Karawanken mountains. While not a full-fledged tourist attraction with extensive exhibits, it provides limited public access to its courtyard and panoramic balcony, appealing to history buffs, hikers, families, and those seeking romantic alpine settings. Its strategic historical role in trade route control and ties to noble families underscore its enduring legacy in Austrian heritage.
The history of Schloss Hollenburg may originate from a curtis ad
Trahoven documented in 860 and 876, potentially linked to an early cave
fortress in the conglomerate rocks below, used for defense and escape.
The present structure was likely built around 1100 by ministeriales of
the Styrian margraves, with the Hollenburg family first mentioned in
1142 through Swiker von Hollenburg, a witness to Viktring Abbey's
foundation. As vassals of the House of Sponheim and later Styria, they
expanded its influence amid the 13th-century development of the Loibl
Pass trade route. The family patronized local institutions, funding
Gothic stained glass for Viktring Abbey's church.
After the
Hollenburg line ended in 1246, ownership transferred to the related
Lords of Pettau, who managed it remotely via stewards. In 1438, it
passed to Agnes von Stubenberg (sister of the last Pettauer), whose son
Johann was embroiled in a 1471 conspiracy against Emperor Frederick III,
leading to the castle's seizure in 1469 by Klagenfurt citizens and its
subsequent pledging to various nobles. Damaged by the 1348 Friuli
earthquake, it was rebuilt and functioned as a land judge's seat in
1349. Further calamities included fires during Turkish invasions (1478),
earthquakes (1571, 1690), and a 1856 lightning strike that destroyed the
roof and battlements.
In 1514, Emperor Maximilian I sold the estate
to his trusted governor Siegmund von Dietrichstein (married to the
emperor's illegitimate daughter Barbara von Rottal), declaring it a
freehold barony. The Dietrichsteins undertook major Renaissance
reconstructions (1516–1588), including the knight's hall, despite
ongoing damages. Protestant family members emigrated in 1621 amid
religious pressures, ceding it to Catholic relatives. The line ended in
1861 with Johann Douglas von Dietrichstein, fragmenting ownership among
heirs (down to 1/41,472 shares). In 1913, industrialist Ludwig "Louis"
Wittgenstein (uncle of philosopher Ludwig Wittgenstein) purchased it. It
passed to the Maresch family in 1923 via inheritance and later to the
Kyrle family, with Dr. Johannes Kyrle restoring it to exemplary
condition.
Schloss Hollenburg is a classic hill/spur castle with an irregular,
elongated layout adapted to the rocky terrain, emphasizing its medieval
defensive origins while incorporating Renaissance refinements. The
northern approach features a mid-17th-century gate tower with a stepped
gable, leading through an 80-meter covered passage over a neck ditch to
the main gate. The exterior appears sober and fortress-like on the
hillside, with plain walls dropping steeply to the Drava, but the
valley-facing side showcases Renaissance twin windows for a more
residential aesthetic.
The five-sided inner courtyard is the
architectural highlight, featuring double-story Renaissance arcades
(built 1558) with an elegant external staircase on one side and a wooden
gallery opposite. The west wall and arcade pillars display prominent
coats of arms, including Dietrichstein-Rottal (1529) and a large
Dietrichstein-Starhemberg alliance emblem. Doors are inscribed with
Lutheran proverbs, Bible verses (from 1581), moral sayings (e.g., from
Livy), and construction dates (1516–1588). Roman-era grave reliefs and
inscriptions are embedded throughout the courtyard, reflecting
antiquarian interests. A unique carving depicts a giant catfish,
commemorating a legendary catch.
The east wing houses the Gothic St.
Nicholas chapel (ground floor, first mentioned 1348, reconsecrated
1684), adorned with a significant fresco cycle from circa 1350–1360
(uncovered in 1945), depicting religious scenes. The western keep
(bergfried), partially demolished and integrated into a Renaissance
structure in 1559, now serves as a viewpoint. Interior spaces like the
knight's hall (16th century) blend functionality with decorative
elements, though not publicly detailed. Overall, the architecture
balances medieval ruggedness—thick walls, caves below for defense—with
16th-century elegance, preserved through restorations despite historical
damages.
As a privately owned residence and event venue, Schloss Hollenburg does not maintain a formal museum or extensive collections. However, accessible areas serve as informal exhibits of its history and artistry. Key highlights include the Gothic frescoes in the St. Nicholas chapel (14th century, depicting religious motifs), Roman antiquities (grave reliefs and inscriptions) embedded in the courtyard walls, and Renaissance decorative elements like inscribed doors with proverbs and coats of arms. The courtyard itself showcases architectural features such as the arcades and staircase. Occasionally, temporary art exhibitions are hosted in summer months, adding contemporary works. The balcony (Söller) offers interpretive value through panoramic views, evoking the castle's strategic past. No artifacts or guided displays are standard, but the site immerses visitors in medieval-Renaissance heritage.
Schloss Hollenburg holds profound historical and cultural importance as a symbol of medieval power in Carinthia, controlling the Drava crossing and Loibl Pass trade route, which facilitated economic and military exchanges between Styria, Carniola, and beyond. Its ownership by dynasties like the Dietrichsteins (linked to Habsburg emperors) and the Wittgenstein family connects it to broader European nobility, politics, and intellectual circles—Ludwig Wittgenstein's uncle owned it during a pivotal era. As a patron site for Viktring Abbey, it influenced regional Gothic art. Surviving earthquakes, wars, and fires, it exemplifies resilient Alpine architecture and the transition from fortress to noble residence. Today, as an event location, it preserves tradition while adapting to modern uses, promoting tourism in the Rosental and highlighting Slovenian-Austrian cultural ties (via its Slovene name). Its caves and views underscore natural integration, making it a niche gem for understanding Carinthian heritage.
