The Château Saint-Jeannet is a notable French castle located about 10km northwest of Nice. Tradition tells that the site was used as a fortress as early the 9th and 10th centuries. However, the earliest known construction on the château hill can only be dated to the 11th century. Written records of a château on the site date to the 13th century. Since that time, it has been effectively destroyed and rebuilt several times. The most recent renovation recovered evidence of the design of that earliest fort, and has attempted to echo it in the placement of the road, outer walls, and observatory tower.
Prior to major renovations completed in 2009, it was known as the Château de la Gaude, because it is situated in the village of La Gaude, just south of Saint-Jeannet proper.
Once the renovation was completed, all the feudal style of the castle was lost. These restorations were not intended to preserve the castle's authenticity but to erect a pseudo luxury hotel that today looks more like a Hollywood cardboard decoration than a feudal castle.
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.
