Oron Castle was built in the 13th century. It was totally rebuilt in second half of the 15th century and renovated several times in the 17th century. In 1801 it was acquired the Roberti family of Moudon, and in 1870 it was bought by Adolphe Gaiffe. Beginning in 1880, a library was built in the castle. Today it houses 17,000 volumes and is one of the largest private collections of French novelists of the 18th Century in Europe. The castle was bought in 1936 by the Association pour la Conservation du château d'Oron, which was founded to preserve the castle two years earlier.
The upper floor of the castle was inhabited by a wealthy middle-class family in the 18th century: majestic entrance, old kitchen, six sitting rooms, and one music room. The library (18,000 books) contains most novels published in French between 1775 and 1825, some of which are unique editions: this is the world’s most important private collection of that period.
The ground floor contains four rooms open to castle guests. Banquets, weddings, birthdays and anniversaries offer the pretext to experience, in one “Murder & Mystery” evening, the atmosphere of the castle steeped in history.
References:Sigmaringen Castle was first mentioned in the year 1077 in the chronicles of Petershausen monastery. The oldest parts of the castle are concealed beneath the alterations made during the 17th and the 19th centuries. The secret of the earliest settlement built on this defendable rock will never be fully revealed: large-scale excavation work would be necessary, which the extensive land development renders impossible. Judging from the many Roman remains unearthed in the area around Sigmaringen, the 12th century keep known as the 'Roman Tower' could be traced back to a Roman predecessor.
The castle remains that have been preserved (gate, great hall and keep) date back to the Staufer period around 1200. The castle remains were integrated into subsequent buildings. The foundations of the castle buildings are to a large extent identical to the surrounding castle wall.
These remains give us a good idea of how the castle might have looked during the 12th century.
