Bernay Abbey (Notre-Dame de Bernay) was established in the first decade of the 11th century by Judith of Brittany who devoted part of the marriage settlement from her husband, Richard II, Duke of Normandy, to its construction. The latter entrusted the completion of the abbey to the Italian, William of Volpiano (died 1028), who reformed the monastery of Fécamp to which he had been called in 1001. After a period of delay in the work, the completion was made by Vital of Creully (appointed in c. 1060, died 1082), the first abbot of the abbey.
The apse was rebuilt in Gothic style in the 15th century and new west facade was added in the 17th century. During the Revolution the church was badly damaged and partially destroyed. The restoration began in 1963.
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.
