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:The Walls of Constantinople are a series of defensive stone walls that have surrounded and protected the city of Constantinople (today Istanbul) since its founding as the new capital of the Roman Empire by Constantine the Great. With numerous additions and modifications during their history, they were the last great fortification system of antiquity, and one of the most complex and elaborate systems ever built. They were also the largest and strongest fortification in both the ancient and medieval world.
Initially built by Constantine the Great, the walls surrounded the new city on all sides, protecting it against attack from both sea and land. As the city grew, the famous double line of the Theodosian Walls was built in the 5th century. Although the other sections of the walls were less elaborate, they were, when well-manned, almost impregnable for any medieval besieger.
