Ottrott Castles

The Ottrott Castles, locally known as Châteaux d'Ottrott, are two remarkable medieval hill castles located on a mountain west of the village of Ottrott in the Bas-Rhin department of France. This region, part of the historic Northern Alsace or the Middle Vosges, is renowned for its scenic landscapes and rich cultural heritage. The Ottrott Castles consist of Rathsamhausen Castle to the west and Lutzelbourg Castle to the east, separated by only about 50 meters, creating a striking visual of two fortresses seemingly facing each other.

Early history and origins

The site originally hosted a primitive castle built before 1076 by the Counts of Éguisheim, who served as notaries to the nearby Mont Sainte-Odile Abbey. This early fortress was strategically placed to oversee the region but was destroyed by the Hohenstaufen dynasty in the early 12th century. The Hohenstaufens quickly rebuilt the castle and granted it as a fief to Conrad von Lutzelbourg. However, in 1198, the castle was burned down by the Counts of Éguisheim-Dabos, marking a turbulent period of local conflicts.

Construction of the two castles

Rathsamhausen castle

In the early 13th century, Otto II, Count of Burgundy, a member of the Hohenstaufen family, constructed Rathsamhausen Castle directly west of the earlier site to reassert control over the region. This castle featured a large rectangular keep built around 1200, which became the central defensive and residential structure. The keep was surrounded by defensive walls and a ditch, enhancing its fortifications. Later, a large round keep was added in response to the construction of Lutzelbourg Castle, highlighting the military tension between the two sites.

Lutzelbourg castle

Lutzelbourg Castle was built in the mid-13th century, just east of the earlier castle site and below Rathsamhausen. It was likely initiated by Heinrich II von Stahleck, Bishop of Strasbourg, as a counterbalance to the Imperialist Rathsamhausen. The two castles, owned by rival powers, were oriented defensively towards each other, reflecting the political and military rivalries of the time.

The name "Lutzelbourg" derives from the German "lutzel Burg", meaning "small castle," first recorded in 1126. The castle’s history is tied to notable figures such as Pierre de Lutzelbourg, who inherited the Magraviate of Suse in Italy but settled on his ancestral lands in Alsace. The large square tower of Lutzelbourg, built in the 12th century, stands 24 meters high with walls 2.4 meters thick, exemplifying robust medieval military architecture.

Medieval conflicts and ownership changes

The rivalry between the two castles was intense during the 13th century, with defensive structures aimed at each other. After the death of the last Hohenstaufen emperor in 1250, Rudolf I of Germany negotiated peace with the Bishop of Strasbourg, ending hostilities by the late 13th century.

By 1392, Lutzelbourg was described as a ruin, likely due to fire or conflict, and Rathsamhausen also suffered damage. In 1393, the Rathsamhausen-Ehenweier family acquired both castles and undertook rebuilding efforts in the early 15th century. The castles changed hands multiple times, including ownership by the Müllenheim family in the 16th century, who introduced significant Renaissance style renovations.

Architectural features and layout

Rathsamhausen castle remains

The ruins of Rathsamhausen Castle reveal a well-planned medieval fortress centered on a four-story rectangular donjon measuring approximately 12 by 16 meters with 1.8-meter-thick walls, rising to 18 meters. Its crenellated battlements provided defensive cover. Adjacent is a 13th-century cylindrical bergfried that once supported a wooden gallery of hoardings, projecting defensive structures allowing defenders to repel attackers.

The castle complex includes a ring wall (enceinte), a zwinger (outer ward), a fortified barbican, and a surrounding ditch isolating the keep. Residential buildings, a kitchen, and a 15th-century structure of uncertain purpose are arranged around a central courtyard, illustrating the daily life and functional organization of the castle.

Lutzelbourg castle remains

Lutzelbourg Castle is perched on a rocky promontory overlooking the Zorn valley. Its most prominent feature is the large square tower from the 12th century, standing 24 meters tall with thick defensive walls. The castle's ruins also include remnants of walls and other defensive structures characteristic of the period.

Later history and preservation

During the Thirty Years' War (1618-1648), both castles were plundered and severely damaged, leading to their abandonment and ruin. Lutzelbourg was ordered destroyed in 1523 by Louis the Pacific to prevent its use by enemies. By the 19th century, the castles were recognized as valuable heritage sites, with efforts to preserve and consolidate the ruins beginning around 1900, notably by Eugène Koeberlé, who conducted excavations and built a neo-Romanesque room on the Lutzelbourg site.

Today, the Ottrott Castles remain private property but are cared for by a volunteer association since 2017, which works to excavate, restore, and stabilize the structures. Visitors can access the site on foot via a forest path, with limited opening times when volunteers are present. The site offers a fascinating glimpse into medieval fortification, regional power struggles, and the architectural evolution of hill castles in Alsace.

Cultural and architectural significance

The Ottrott Castles provide a unique example of two closely situated medieval hill castles that reflect the complex feudal and political dynamics of the Alsace region during the High Medieval period. Their architecture showcases typical defensive features such as keeps, bergfrieds, ring walls, barbicans, and moats, alongside residential and service buildings adapted over centuries.

The juxtaposition of the two castles, built by rival powers facing each other, illustrates the strategic importance of the site and the interplay between secular and ecclesiastical authorities. The Renaissance renovations introduced by the Müllenheim family add a layer of stylistic and historical depth, marking the transition from purely military fortresses to more comfortable noble residences.

Conservation efforts continue to preserve these ruins as a cultural landmark, contributing to the understanding of medieval military architecture and Alsace’s historical landscape.
