Les Rochers was the estate of the Mathefelon family from the 12th century, before being passed by marriage to the Sévigné family in 1410. The family rebuilt the château in the early 16th century. Between 1644 and 1690, Madame de Sévigné stayed here and refurnished the house. She gave names to the paths through the gardens and in 1689 her son commis-sioned the French Gardens from Le Nôtre. In 1715, the Nétumières family bought the estate and carried out building and restoration works. Today there is a visitor centre at the 17th century Orangerie and exhibition about Madame de Sévigné and the Château des Rochers.
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.
