Constructed: 1170

 

The Château de Haut-Barr, also known as Hohbarr or Burg Hohbarr, is a medieval castle ruin located above the town of Saverne in the Bas-Rhin department of Alsace, northeastern France. Perched on a sandstone outcrop at an elevation of 460-470 meters, it overlooks the Zorn Valley and the Plain of Alsace, earning the nickname "the eye of Alsace" since the Council of Constance in 1415 due to its panoramic views extending to the Vosges Mountains, the Black Forest, and even the spire of Strasbourg Cathedral on clear days. Constructed primarily from local sandstone, the castle spans three large rock formations connected by a footbridge known as the Pont du Diable (Devil's Bridge), creating a dramatic and strategic site. Originally built as a defensive stronghold by the bishops of Strasbourg, it exemplifies rock-integrated medieval architecture with features like a portcullis entrance, well tower, castral chapel, and artillery remnants. Classified as a monument historique since 1874, the ruins are now a popular tourist site maintained by the Castrum Borra association and owned by the city of Saverne, accessible via a short walk from a parking area on the D171 road.

 

History

Origins and Construction (12th Century)
The castle's origins trace back to the 12th century, with the first structure built around 1100, though some sources specify 1170 as the date of erection by the Bishop of Strasbourg. Its primary purpose was to control and surveil the Zorn Valley, a key passage between the Lorraine Plateau and the Alsace Plain, as well as to monitor trade routes and potential invasions. The site was chosen for its natural defensibility: three massive sandstone rocks, separated by deep chasms, provided inherent protection. These rocks were linked by the iconic Pont du Diable, a narrow footbridge spanning a void, which became central to the castle's layout. Early construction focused on basic fortifications, including walls adapted to the rugged terrain and a central keep for residence and defense. The bishops of Strasbourg, who held ecclesiastical and temporal power in the region as part of the Holy Roman Empire, oversaw the initial build and subsequent expansions, using the castle as a strategic outpost.

Medieval Period and Expansions (13th–15th Centuries)
Throughout the medieval era, Château de Haut-Barr underwent several expansions under the bishops of Strasbourg, solidifying its role as a fortified residence. By the 14th century, it was transformed and restored, incorporating Romanesque and Gothic elements such as arched gateways and defensive towers. The castle's design exploited the natural rocks: the western rock housed the main entrance with a portcullis, leading to a caretaker's lodge and well tower; the central rock featured the castral chapel and lord's residence; and the eastern rock included artillery tower vestiges. This period saw the castle involved in regional power struggles within the Holy Roman Empire, though specific conflicts from this time are less documented. Its elevated position made it an ideal vantage point, contributing to its "eye of Alsace" moniker during the Council of Constance (1414–1418), where it symbolized surveillance over the region.

Renaissance Transformations and Later Conflicts (16th–18th Centuries)
The 16th century marked a significant phase of modernization under Bishop Jean de Manderscheid-Blankenheim, who transformed and restored the castle in 1583, residing there frequently. These works included reinforcements to adapt to artillery warfare, such as the addition of gun ports and bastions, blending medieval defenses with Renaissance aesthetics. The castle endured the turmoil of the Thirty Years' War (1618–1648), after which the Peace of Westphalia (1648) mandated its partial dismantling to prevent further military use, reflecting the treaty's efforts to demilitarize the region.
However, it was reactivated as a fortress at the onset of the War of the Spanish Succession (1701–1714), occupied by soldiers to defend French interests in Alsace. By around 1770, it was largely abandoned, though its vaulted areas continued to be used until the French Revolution (1789–1799). In 1798, a Chappe telegraph—an early optical communication system—was installed nearby, linking it to broader networks during the Napoleonic era.

Decline and Modern Preservation (19th Century–Present)
Following its abandonment, the castle fell into ruin, overgrown and neglected until the 19th century when romantic interest in medieval sites spurred preservation efforts. It was classified as a monument historique in 1874 by the French Ministry of Culture, granting legal protection. The city of Saverne acquired the property in 1970, initiating restoration projects to stabilize the structures and make them accessible to the public.
Today, the ruins are open year-round, with visitors able to explore the Devil's Bridge, chapel, and panoramic terraces. Maintenance is handled by the volunteer association Castrum Borra, which organizes events and guided tours. The site attracts hikers and history enthusiasts, offering views that underscore its historical surveillance role. While not fully restored, ongoing conservation ensures the preservation of its sandstone features against erosion.

Notable Facts and Legends
One of the castle's most famous legends surrounds the Pont du Diable: According to folklore, the bishop, facing construction challenges over the chasm, made a pact with the devil to build the bridge in one night in exchange for the soul of the first to cross it. Upon completion, a stray dog was sent across, infuriating the devil who stamped his foot, leaving a permanent mark on the rock. This tale highlights the bridge's engineering marvel and adds a mystical element to the site.
Architecturally, the castle's integration with the natural rock formations sets it apart, with features like the well tower for water supply during sieges and the chapel's preserved arches. Its strategic importance through centuries of European conflicts underscores Alsace's borderland history, making it a symbol of regional resilience.

 

Architecture

Overall Layout and Structure
The castle's unique layout is defined by its adaptation to three narrow, elongated sandstone spurs or rocks, which form a natural foundation and defensive barrier. These rocks are connected by the iconic Pont du Diable (Devil's Bridge), a narrow stone footbridge spanning a dramatic void between two of the spurs, adding both functional access and a mythical element to the design. The structure spans a rugged, elevated site, with the main entrance featuring a portcullis that leads to the caretaker’s lodge and well tower, providing controlled access to the inner areas. Key components include the castral chapel, remnants of the artillery tower, and the lord’s residence, all clustered on the rocks to maximize the site's defensive potential. The layout emphasizes verticality and integration with the terrain, creating a compact yet expansive fortress that exploits the natural cliffs for protection. Surrounding forests and the steep drop-offs enhance its isolation, making it a classic example of a rock castle (rocher château) in the Vosges region.

Towers
The castle features several towers that contribute to its defensive and residential functions. The well tower, located near the entrance, served as a vital water storage and access point, integrated into the main pathway. The artillery tower, added or modified in the 16th century, now exists only as vestiges but was designed to house firearms, reflecting adaptations to evolving warfare. These towers are cylindrical or semi-cylindrical in form, built directly from the sandstone bedrock, with narrow slits for archers or cannons. Additionally, the site's elevated spurs themselves act as natural "towers," providing high vantage points for observation.

Keep
While not a traditional single keep structure, the castle's core defensive element is embodied in the lord’s residence and associated buildings on the central rock, which functioned as a keep-like stronghold. This area includes remnants of multi-level stone buildings with thick walls, designed for both habitation and last-resort defense. The integration with the rock formation provides inherent strength, with the Devil's Bridge serving as a precarious access route to isolated sections.

Defensive Features
Haut-Barr's architecture prioritizes defense through its elevated, rocky position, which offers natural cliffs and steep approaches as barriers against invaders. Key man-made elements include the portcullis at the entrance for controlled access and the artillery tower for ranged weaponry. Narrow slits in walls and towers allowed for archery or cannon fire, while the Devil's Bridge created a chokepoint that could be easily defended or destroyed. The site's isolation and height made sieges difficult, emphasizing passive defense over elaborate battlements.

Materials and Construction Techniques
The castle is primarily constructed from local sandstone, quarried directly from the site's spurs, which provides durability and seamless integration with the natural rock. Walls and structures feature roughly hewn blocks mortared together, with finer detailing in areas like the chapel's arches. The Devil's Bridge exemplifies advanced medieval engineering, built as a slender arch over a deep chasm, possibly using scaffolding or cantilever methods, though legend attributes it to supernatural aid. Construction exploited the rock's contours, minimizing excavation and enhancing stability.
