Location: Spitz Map
Found: 12th century
Hinterhaus Castle (German: Ruine Hinterhaus or Oberhaus) is a
dramatic medieval ruin perched on a rocky spur of the Jauerling
mountain above the village of Spitz an der Donau in Austria’s Wachau
Valley (a UNESCO World Heritage site along the Danube River in Lower
Austria). First documented in 1243 as “castrum in monte” (“castle on
the mountain”), its origins trace back to the late 12th century. It
served as a strategic stronghold for the powerful Kuenringer family
and the Knights of Spitz, who used it to control Danube shipping and
the surrounding valley.
The castle’s terraced layout—divided into
a northeastern lower bailey, the main castle, and a southwestern
bailey—includes well-preserved defensive walls, a prominent square
keep, and remnants of a Romanesque palace. Though largely ruined (it
was likely destroyed or abandoned around the early 15th century),
the freely accessible site still offers sweeping views of the
Danube, vineyards, and the village below. Its isolated, atmospheric
ruins have long inspired folklore, with locals and visitors noting
it feels “haunted to this day.”
Origins and Construction (Late 12th – Early 13th Century)
The
oldest section—the main castle—dates to the late 12th century (around
1180). Historians generally credit the Formbacher family, an old
Bavarian noble line, with its initial construction, though it soon came
under broader regional powers. The castle was built as a strategic
castrum in monte (“castle on the mountain”) to control Danube river
traffic, trade routes through the Wachau Valley, and the surrounding
wine-growing lands.
In 1242, the fief passed from Niederaltaich Abbey
(a Bavarian monastery) to the Dukes of Bavaria. Shortly afterward, the
Bavarians granted it as a sub-fief (Afterlehen) to the powerful
Kuenringer (Kuenring) family, one of medieval Austria’s most influential
ministerial dynasties. The Kuenringers did not usually live at
Hinterhaus themselves but installed loyal burgraves and ministeriales
(knights) to administer it. The first documented reference to the castle
appears in 1243 (as “castrum”) in a fief report by Abbot Hermann of
Niederaltaich. By 1256 it is explicitly recorded as the fortress of the
Kuenringer knight Arnold von Spitz.
The Age of the Knights of
Spitz (13th–14th Centuries)
During the 13th and 14th centuries, the
Ritter von Spitz (Knights of Spitz), vassals of the Kuenringers, resided
in the castle. It functioned primarily as an administrative and military
stronghold rather than a luxurious residence. The Kuenringers used their
network of Wachau castles (including Hinterhaus/Oberhaus and the nearby
Unterhaus/lower castle in the town itself) to dominate the valley
economically and militarily. The red-gate entrance and defensive walls
from this era still give visitors a vivid sense of medieval
fortifications.
The Kuenringer male line died out around 1335–1355.
After their extinction, the lordship of Spitz (including Hinterhaus)
passed first into pledge possession with the Wallsee family, then in
1385 to the Maissau family.
Destruction, Rebuilding, and
Late-Medieval Turmoil (1409–1500)
In 1409, during the Habsburg
fraternal dispute over the guardianship of the young Albrecht V,
Hinterhaus was captured and largely destroyed. Duke Ernst of Bavaria
reconquered it from Otto IV von Maissau in 1438 and had it rebuilt.
Around 1440 it was granted to the Lords of Neidegg.
The castle
continued to see action: in 1463 it successfully withstood a siege by
the mercenary leader Pankraz von Planckenstein, but in 1493 it fell to
Hungarian troops (during the conflicts under King Matthias Corvinus). By
around 1500 the lords had moved to the more comfortable Unterhaus in the
town below; Hinterhaus was no longer permanently inhabited and began its
slow decline into ruin.
Transition to Habsburg Rule and Early
Modern Refortification (1504–Late 16th Century)
A major turning point
came in 1504 after the Bavarian War of Succession: Bavarian holdings in
Austria, including the Spitz lordship, passed to Emperor Maximilian I
and became sovereign Habsburg territory (landesfürstlich), ending the
region’s semi-extraterritorial status. In 1507 the castle entered
freehold ownership with Eitelfritz von Zollern.
Because of the
ongoing Ottoman (Turkish) threat in the 16th century, the southwestern
bailey was expanded and refortified with round corner towers adapted for
firearms (hackbuts/hand cannons) and artillery. Features such as pitch
holes (for pouring boiling substances) and modified arrow slits date to
this phase. The castle was never again a primary noble residence but
served as a defensive outpost.
Subsequent owners in the late 16th and
17th centuries included Freiherr Matthias Teufel and Hans Georg von
Kuefstein (1590), the Geyer von Osterburg family (1646), the
Abensberg-Traun family (1667), and the Dietrichstein family (1674).
Further Destruction and Abandonment (17th–19th Centuries)
In
1620, during the early phase of the Thirty Years’ War, imperial troops
under General Bouquoy destroyed the castle; it was never repaired. The
already ruined structure suffered additional damage during the
Napoleonic Wars (French campaigns of 1805 and 1809).
Ownership passed
through various hands: in 1871 it went to the Wiener Bürgerspitalfonds
(Vienna Citizens’ Hospital Fund), in 1918 to the Kriegsgeschädigtenfonds
(War Victims’ Fund), and later to the Austrian Federal Forests
(Österreichische Bundesforste).
Modern Preservation and Current
Status (20th–21st Centuries)
In 1970 the ruins became the property of
the market community (Marktgemeinde) of Spitz. Since 1977 the local
tourism association (now the Verein Ruine Hinterhaus) has carried out
ongoing restoration and maintenance work—clearing vegetation, repairing
masonry joints, and preserving the site. It remains freely open to the
public year-round and is a popular hiking destination, often reached via
steep paths from Spitz or the Spitzer Graben.
Architectural
Highlights Tied to Its History
Romanesque keep (Bergfried): A massive
square tower (about 20 m / 65 ft high, 7.2 m sides) in the northwest
corner of the main castle, dating to the 12th–13th century. Its high
entrance (6 m up) and internal staircase are classic defensive features;
today it serves as an observation platform.
Palas (residential hall):
Remains of 8–10 m high walls suggest a multi-story building in the main
castle.
Outer baileys: The northeastern one (13th–14th centuries) has
well-preserved battlements and a round-arched gate; the southwestern one
(15th–16th centuries) includes artillery-adapted towers and a cistern.
The entire complex adapts ingeniously to the narrow rocky terrain, with
four round corner towers on the vulnerable narrow ends.
Overall Layout and Topography Integration
The castle follows the
natural contours of a narrow rock spur that descends from southwest to
northeast. It forms an elongated, terraced complex approximately 75
meters long and up to 20 meters wide, creating a longitudinally
rectangular plan with walls bent several times to hug the terrain. This
terraced design maximizes defensibility on the steep slopes while
providing commanding views of the Danube.
The structure divides
clearly into three main sections:
Northeastern (lower) outer bailey
(Vorburg): The lowest and most accessible part, with deeper terraces and
later defensive additions.
Central main castle (Hauptburg): The
largest and highest section, occupying most of the rocky ridge; this
contains the core residential and defensive elements.
Southwestern
outer bailey: The upper/rear section, separated by a strong dividing
wall.
This layout reflects typical medieval castle evolution on
constrained sites—starting compact and expanding outward in phases for
better control and fortification.
Construction History and
Architectural Phases
12th–13th centuries (Romanesque core): The
oldest parts, including the main castle, date to the 12th century (first
documented mention in 1243). The central keep and initial palace (Palas)
were built then. Masonry from this era uses coarse-block quarry stone,
often plastered.
13th–14th centuries: Expansions under the Knights of
Spitz (vassals of the Kuenringers). Multi-phase buildings in the
northern courtyard incorporate a high-medieval palace.
14th–15th
centuries: Further wards and outer baileys added; some destruction and
rebuilding (e.g., after 1409).
15th–16th centuries (late Gothic to
early Renaissance refortifications): Major upgrades in response to
threats like Turkish invasions and regional conflicts. This included
round artillery towers, a neck ditch enclosure, and firearm-adapted
loopholes. The castle was destroyed again around 1620 and during the
Napoleonic/French wars (1805/1809) but saw partial refortification
earlier.
Later owners (Wallsee, Maissauer, Kuefstein, etc.)
maintained or refortified it until it fell into disuse as a "Burgstall"
(castle site) by the early 16th century in some records.
Key
Architectural Features
The Keep (Bergfried): Located in the northwest
corner of the main castle at the highest point. This is a massive square
Romanesque tower, about 7.2 meters per side and around 20 meters high,
built with ashlar (dressed stone) masonry. Key details include:
High
entrance roughly 6 meters above ground level (typical for security).
Internal stairways within the wall thickness leading from the first
floor upward.
Arched windows and rectangular slits for defense/light.
Groined vault of quarry stone on the second floor; a domed vault in a
corner section.
Originally multi-storey with a defensive platform
(now a modern lookout with iron stairs and panoramic Danube views). Beam
holes under preserved battlements indicate former wooden fighting
platforms.
Baileys and Courtyards:
The main castle features a
central courtyard with a deep well/cistern (still visible and secured
today) for water security.
Northern courtyard: Multi-phase
residential buildings (14th–16th centuries) integrating earlier palace
wings.
Southeastern small three-part ward (likely 14th century).
Outer baileys include terraces with traces of medieval outworks later
modified by vineyards.
Walls, Towers, and Defensive Elements:
Enclosing walls are thick and adapted to the rock, with a bering
(curtain wall) encompassing corners.
Four round, two-storey corner
bastions (part of the outer fortifications): Built of coarse quarry
stone with renewed rectangular battlements. Eastern towers feature
loopholes for crossbow defense; western ones have slits suited for
arquebuses/handguns (firearm combat), showing 15th–16th-century
adaptations.
Mountain-side enclosure: Includes a neck ditch
(partially overbuilt) and two slim, overhanging round towers with early
Renaissance features—funnel-shaped slits for handguns, limited
decorative battlements.
Gates and portals: Access via a steep
northern path to a round-arched portal into the eastern outer bailey.
Another arched portal (with pecherker, or defensive overhang for pouring
pitch/hot substances) leads into the inner courtyard. A reconstructed
original gate system sits next to the keep. The "Red Gate" (Rotes Tor)
is famously associated with the ruins (or nearby fortifications); it
evokes medieval defense methods and serves today as a popular
viewing/meeting point in Spitz, though its exact castle integration ties
into the broader defensive network.
Materials: Predominantly local
coarse quarry stone and ashlar for structural elements, with plastering
("Stuck") in places. Later phases added refinements for artillery.
Current State and Visitor Experience
Today, Hinterhaus is a ruin
with substantial standing walls, the prominent keep (accessible as a
viewpoint), bastions, and terraces. Visitors hike a short steep path
(about 10 minutes) and can explore the elongated layout, climb
stairs/ladders in the tower, and appreciate the defensive ingenuity. The
site remains free and open 24/7, offering stunning vistas of the Danube
and Wachau vineyards. While not fully restored, the visible phases—from
Romanesque keep to Renaissance gun towers—provide a clear picture of
evolving medieval-to-early-modern castle architecture in the region.
The Central Legend: The White Lady (Schloßgeist / Weiße Frau) of
Hinterhaus
The most famous and enduring legend associated with
Hinterhaus revolves around the ghost of Adelheid (sometimes spelled
Adel-Held), the first wife of Heinrich der Eiserne (“Henry the Iron”), a
13th-century Kuenringer lord who ruled the castle. This tale of
betrayal, divine punishment, and restless spirits appears in multiple
20th-century collections of Wachau sagas and is the one consistently
repeated in travel accounts, local guides, and oral tradition.
Full Traditional Version (from Josef Wichner’s Wachausagen, ca. 1920)
Above Spitz, guarding the entrance to the Ranna Valley, the ruin of
Hinterhaus rises on the slope of the Jauerling. Here, in the second half
of the thirteenth century—when Rudolf of Habsburg wore the crown of the
Empire—lived the Kuenringer Heinrich, nicknamed “the Iron” for his
bravery. Unlike his kin (called the “biting dogs”), he was a righteous
man, loyal to the king and a valiant follower in the wars against
Ottokar of Bohemia.But Heinrich showed less fidelity in his married
life. After the death of his first wife, Adelheid von Feldsberg, he
remarried within a few months, without devoting a year of mourning to
the deceased. Such disregard for the customary year of mourning was
greatly resented by all, and when he himself soon afterward died a
sudden death, people saw in it a punishment from Heaven.Since that time,
things have not been right in the castle—and later in the ruin. Many
claim to have seen the spirit of Adelheid appear every year on the night
of Heinrich’s death… in a snow-white burial shroud, waving with her dead
hand… Indeed, the old woman from the Erlahof firmly insisted that once,
when she was gathering wood and stayed out until nightfall, she heard
Lady Adelheid lamenting over and over: “Nit ein Jahr! Nit ein Jahr!”
(“Not even one year!”).
Variant from Hans Plöckinger’s Sagen der
Wachau (1926)
This version is nearly identical but emphasizes
Adelheid’s short marriage and the public outrage at Heinrich’s
“heartlessness.” The ghost is again described as a woman in snow-white
garments waving with her “dead hand” from the windows of the ruined
castle, crying “Nit ein Jahr! Nit ein Jahr!” because of her husband’s
infidelity and failure to observe the mourning period.
Popular
English Retelling
Some modern accounts add colorful details: Adelheid
died in childbirth inside the castle, and Heinrich quickly became
enamored with a beautiful young woman from the village of Spitz below.
He rushed into a second marriage, only to die mysteriously soon
afterward. On the anniversary of his death, Adelheid’s ghost is said to
appear at a specific window, screaming in anguish.
Why This
Legend Endures
Moral Core: The story enforces medieval Christian and
social norms around mourning, fidelity, and respect for the dead.
Heinrich’s hasty remarriage violated the unwritten “Trauerjahr” (year of
mourning), turning a personal failing into a cautionary tale of hubris
and divine justice.
Haunting Imagery: The “White Lady” archetype is
common in European folklore (similar to other Weiße Frauen in Austria
and Germany), but here it’s localized with specific details—the ruined
windows, the dead hand waving, the repeated cry “Nit ein Jahr!”—making
it vivid and eerie.
Setting: The castle’s dramatic hilltop ruins,
especially at night or in moonlight, lend themselves perfectly to ghost
stories. Skeptics in the sagas themselves attribute sightings to
“moonlight and wind whispering through the old masonry,” but believers
see it as the embodiment of folk moral ideals.
While sources
often mention “many legends and stories” surrounding the ruins, no other
named tales (e.g., involving knights, treasures, or different ghosts)
are prominently documented in historical or folk collections. The White
Lady of Hinterhaus remains the defining supernatural legend of the site.
