Built from 1306 during the village fortification by the Comte de Savoie Amédée V, Yvoire castle had a military goal to watch the navigation and control the road which linked Geneva to the high valley of the Rhône and to Italy.
For several centuries, the village of Yvoire was in the center of several strategic or religious wars between France, Bern, Geneva as well as the houses of Faucigny, Dauphiné and Savoie.
In 1591, a fire devastated the building which only found its shape back in the 20th century, when Félix Bouvier of Yvoire undertook several internal and external renovation works, like the roof and the watch towers setting in 1939.
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.
