The Cathedral Notre Dame de la Nativité, built in the 4th century took its final shape in the 12th century. The Tower Saint Lambert, vestige of the Bishop's Palace of France dates from the same period.
Inside, the size of the building can be surprising, but one is very quickly charmed by all the marvels which it contains: a fragment of a sarcophagus with low Gallo-Roman reliefs, pieces of Carolingian sculptures and a set of polychromatic wooden statues representing the Way of the Cross dating from the 17th and 18th centuries, the jewel of the Vençois religious heritage.
This sacred place shelters a baptistery decorated by Marc Chagall's mosaic representing Moses saved from the waters. Chagall who lived in Vence from 1950 to 1966 wanted to express the joy of baptism by this theme.
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.
