Rhäzüns Castle

Rhäzüns Castle stands as one of the oldest surviving castles in Switzerland, with origins tracing back to the 10th century. Its earliest recorded mention dates to 960, when Emperor Otto I transferred a church located in "in castello Beneduces et Ruzunnes" (the castle of Bonaduz and Rhäzüns) to the Bishop of Chur. This transaction, confirmed again by Otto II in 976, provides the first documentary evidence of the castle's existence. Originally, the site housed a fortified church that gradually evolved into a feudal stronghold over the subsequent centuries.

The castle is located strategically on a cliff above the Hinterrhein river, near the village of Rhäzüns in the canton of Graubünden. Its position afforded commanding views and control over the surrounding valley, a key factor in its historical significance. The castle's early defensive structures likely included a ring wall encircling the site, though this original fortification was partly lost due to erosion caused by the river.

Medieval origins and noble lineage

By the 12th and 13th centuries, Rhäzüns Castle had become the seat of the powerful Rhäzüns family, a Romansh noble lineage first appearing in records in 1139 with Arnoldus de Ruzunne. The castle’s first explicit mention as a fortress dates to 1282. Over the centuries, the Rhäzüns family expanded their influence, acquiring lands in Domleschg and around Heinzenberg Castle. Their growing power culminated in 1343 when a peace treaty between Disentis Abbey and Glarus was signed in the castle's courtyard, underscoring its role as a regional political center.

The late 14th century saw tensions rise between the Rhäzüns family and the Bishop of Chur, leading to the formation of the Ober Bund or Upper Alliance in 1395. This alliance, including the abbot of Disentis Abbey and other regional nobles, sought to counterbalance episcopal power. However, the prolonged conflict weakened the Rhäzüns family, who eventually joined the Grey League in 1424, a significant political federation in the region.

Ownership changes and architectural evolution

The death of Georges Brun von Rhäzüns in 1458 without heirs sparked a dispute over the castle’s inheritance. After a prolonged conflict, the castle and its lands passed to Niclas von Zollern in 1473. Ownership changed hands frequently in the following centuries, involving families such as the von Marmels, von Stampa, von Planta, and the Planta-Wildenstein lineage. The castle also became a Habsburg fief, reflecting the broader political shifts in the region.

During the Swabian War in 1499, troops of the Three Leagues occupied Rhäzüns Castle to prevent it from becoming a Habsburg stronghold. In 1553, significant structural changes were necessary when the eastern round bergfried was demolished due to erosion by the Hinterrhein river threatening collapse. The 16th century also saw the addition of a mill, bath houses, a jail, and residential buildings, reflecting the castle’s adaptation to changing needs.

17th-century expansions and Austrian administration

Under Austrian control, the castle underwent further modifications. The hereditary fief was dissolved in 1595, and a vogt (bailiff) was appointed to administer the territory. The vogt added a chapel on the north side and an outer gatehouse on the south-west side around 1700. The castle served as the residence for various Austrian vogts over the next two centuries, maintaining its administrative importance.

Modern history and preservation

Following the Napoleonic Wars, the castle changed hands again. Austria ceded Rhäzüns to Napoleon in 1809, reclaimed it in 1814, but the Congress of Vienna in 1815 transferred it to the Canton of Graubünden. The canton sold the castle to private owners in 1823, and it served various roles including a private residence for the Vieli family and later a girls' school. After a period of neglect, the castle was restored in the early 20th century and converted into a vacation resort by 1929.

World War II halted tourism, leading to abandonment of the resort. In 1960, the castle was acquired by Ems-Chemie and later rented by Christoph Blocher, a prominent Swiss politician, until his death. Today, Rhäzüns Castle remains closed to the general public but maintains a unique educational tradition: for over 30 years, fourth-grade students from the local school have been invited annually to tour the historic site.

Architectural features and layout

Rhäzüns Castle's architecture reflects its long history and the adaptations made over centuries. The original castle likely featured a ring wall encircling the site, though the eastern section was lost due to river erosion. The surviving north and south walls terminate at the cliff edge, with a newer wall along the cliff forming the current eastern boundary.

The 14th-century inner gate tower and northern residential wing are notable for their preserved frescoes, including the coat of arms of the Barons of Rhäzüns and a hunting scene. The 16th-century reconstruction introduced the eastern wall after the bergfried's demolition, along with repairs and renovations to existing structures.

The 17th-century outer gatehouse and chapel on the north side were later additions under Austrian administration. Residential quarters were expanded during the 16th and 17th centuries, reflecting the castle's evolving function from a feudal fortress to an administrative center and noble residence.

Today, Rhäzüns Castle stands as a well-preserved hill castle that embodies the complex feudal and political history of the Graubünden region. Its combination of medieval fortifications, Renaissance modifications, and Baroque-era expansions offer valuable insights into the architectural and historical developments of Swiss castles over the last millennium.
