The château de Mesnil-Voisin was built by Michel Villedo in 1632-1635. It has an orangery, kitchens, coachhouses and workshops. At the centre of its communal courtyard a huge dovecote with 3000 niches and a wood-framed roof, and topped by a conical turret - it is rare in having its internal moveable staircase still intact.
The course of a canal bordering the rear of the château were entirely removed between 1999 and 2001. It has thus returned to its original course, leaving the Juine a short distance upstream of the château and rejoining it some distance downstream, just before the pont de Cochet.
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.
