Friedau Castle

Friedau Castle in Zizers, Switzerland, is a significant medieval structure with origins tracing back to the 10th century lands granted by Emperor Otto I to the Bishop of Chur in 955. The castle likely occupies the site of earlier buildings from this period, establishing its long-standing historical importance in the region.

The construction of the current castle began under Bishop Volkart von Neuenburg between 1237 and 1251 and was completed during the tenure of Heinrich IV von Montfort from 1251 to 1272. This places the castle firmly in the High Medieval period, reflecting typical architectural and functional characteristics of that era. Once completed, Friedau Castle became the administrative center of the Herrschaft and the residence of the bishop's landvogt (bailiff), highlighting its role in regional governance and ecclesiastical authority.

Historical significance and ownership changes

Throughout its history, Friedau Castle was closely tied to the financial and political needs of the Bishop of Chur. The bishop frequently used the castle as collateral for loans or as a reward for donations, indicating its value and strategic importance. In 1358, the castle was pledged to the Beringers von Landenberg, and just four years later, in 1362, it was granted to Kunigunde von Toggenburg. The Toggenburg family maintained control until the death of Frederick VII in 1436, which marked the extinction of the family line.

By 1387, the castle had fallen into ruin, and the bishop was granting only the rights to the associated lands and taxes. Importantly, a clause was included that if the castle was ever rebuilt, those lands would revert to the bishop's control. This legal arrangement reflects the castle's ongoing strategic and economic importance even during periods of physical decline.

Reconstruction and later uses

Despite its ruinous state in the late 14th century, Friedau Castle was rebuilt sometime after the Toggenburg extinction, as records from 1503 mention the presence of a vogt at the castle. By 1550, chronicler Ulrich Campell described the castle as a tower surrounded by a wall and moat, indicating a fortified structure typical of the period.

In 1649, the bishop sold the castle to the Vier Dörfer (Four Villages), after which the castle was repurposed as a prison. It gradually became known as the Schelmenturm, a name reflecting its penal function. This transition from administrative center to prison illustrates the castle's adaptive reuse over centuries.

Architectural features and condition

The castle is a square tower measuring approximately 11.5 by 11.5 meters, with walls up to 2.3 meters thick, emphasizing its defensive design. Originally, it stood four stories tall with a high entrance located on the second story of the east side, a common medieval defensive feature to hinder attackers.

In 1880, a devastating fire severely damaged the tower and much of Zizers. The intense heat caused the stone walls to crack, resulting in two large rents in the tower's structure, which remain visible today. These damages have affected the castle's preservation state, now classified as partially preserved.

Archaeological findings

During an archaeological excavation in 2016, several human bones were discovered within the tower, including finger, foot, and leg bones. Initial theories suggested these remains belonged to tortured prisoners from the castle's time as a prison. However, Carbon-14 dating revealed that the bones predated the castle's 13th-century construction, indicating an earlier historical layer at the site.

Location and cultural importance

Friedau Castle is situated in the center of Zizers, in the canton of Graubünden, Switzerland, not Luzern as sometimes mistakenly noted. Its central location within the town underscores its historical significance as a local power center and administrative hub.

The castle's enduring presence reflects the complex feudal and ecclesiastical history of the region. It serves as a tangible link to medieval governance, territorial control, and the evolving functions of fortified structures over time.

Visitor information

Today, Friedau Castle stands as a partially preserved monument, with visible signs of its medieval architecture and the scars of historical events such as the 1880 fire. Visitors interested in medieval history and castle architecture can appreciate its robust defensive features and its layered history that spans from the early medieval period through its later use as a prison.
