History
Old Worb Castle is a historic noble residence in Worb, Switzerland, whose core predates 1130 and was built for the barons of Worb. The castle became the centre of a lordship, a territorial estate governed by a noble family, and later passed among several Bernese families. Its surviving form reflects repeated rebuilding from the fifteenth through the seventeenth centuries.
The Barons of Worb and Bernese Authority
The barons of Worb are first recorded in the early twelfth century. In 1146, Duke Conrad I of Zähringen held court at their lordly residence. Conrad belonged to the Zähringen dynasty, a medieval noble house whose territories included areas of present-day Switzerland and southwestern Germany.
By the late thirteenth or early fourteenth century, the von Kien family had acquired Worb. Members of the family became citizens of Bern in 1336, bringing the territory under Bernese authority. During the fourteenth and fifteenth centuries, the lordship passed from the von Kien family to the von Diesbach family. Niklaus von Diesbach took possession in 1469 and reunited the divided estate.
Rebuilding and Changes of Ownership
The castle was repeatedly altered and enlarged between 1469 and 1594. A fire in 1535 resulted in the construction of a largely new castle, changing the physical character of the residence while preserving its role as the centre of the Worb estate.
By the end of the sixteenth century, the lordship had been divided among three co-owners and was later subdivided further. Christoph von Graffenried reunited its parts in 1668. The estate remained with the von Graffenried family until 1792, when an heirs’ community sold it to Johann Rudolf von Sinner, a member of the Bernese patriciate. Ownership subsequently changed several times.
The Separate New Castle
A separate manor was built beside Old Worb Castle in the eighteenth century. Later known as New Worb Castle, Neuworb, or the New Castle, it was constructed by Franz Ludwig von Graffenried, the son of Christoph von Graffenried. The two estates were acquired by the Goumoëns-Sinner family in 1846. Old Worb Castle was bought by the Seelhofer family in 1964, while the New Castle was acquired by the von Graffenried family in 1985.
Old Worb Castle remains privately owned and is designated a Swiss cultural property of national significance.
Remains
Old Worb Castle preserves a complex that began with a keep, a great hall, and a knight’s house. Repairs and enlargement in 1469 and 1594, followed by later residential construction, produced a layered group of buildings rather than a single unchanged medieval structure.
Castle Buildings and Interiors
Early Castle Core
The castle’s core predates 1130 and originally consisted of a keep, a great hall, and a knight’s house. These buildings formed the principal elements of the early noble residence. The complex was renovated and repaired in 1469 and again in 1594, and the fire of 1535 led to the construction of a largely new castle.
Baroque Residential Building
A new residential wing was added in 1643. The residential building is described as a seventeenth-century Baroque structure. Its interior contains a collection of rural glassware, while rooms on the bel étage, the principal residential floor above the ground floor, retain painted linen wall coverings.
New Castle
The New Castle is a separate, ornate manor beside Old Worb Castle. Built in the eighteenth century by Franz Ludwig von Graffenried, it forms a distinct estate and should not be confused with the older castle or its earlier residential buildings.
