The Collegiate Church of Saint-Vulfran in Abbeville is built in a Flamboyant Gothic style. The construction of the church was started on 7 June 1488. From 31 August it was clear that funding would be an issue and thus the construction was ceased for some time. On 4 April 1520 Jean Crétel of Tours-en-Vimeu was commissioned to lead the work. The nave would be under construction until 1539. Construction resumed 120 years later when the choir was built in two years, from 1661 to 1663 in a more simplified style.
As the French Revolution took place, the church became a Temple of Reason and a feast was celebrated in honor of the Supreme Being on 8 June 1794. Catholic worship in the church resumed in 1803. The church was listed as a Monument historique in 1840.
The church was heavily damaged on 20 May 1940 by German bombings as part of the Battle of France in World War II. The restoration of the church was not completed until 1998.
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.
