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:Krickenbeck moated castle is one of the oldest on the lower Rhine. Its history dates back to the year 1104, when the castle was first mentioned. It is unclear why the old castle, which was certainly inhabited by Count Reginar, was abandoned or destroyed. In the mid-13th century the castle was moved to the current location. At the end of the 14th century the new castle belonged to the Counts of Kleve.
Johann Friedrich II of Schesaberg converted the castle into a Baroque mansion between 1708-1721. On September 7, 1902, a fire destroyed the entire mansion. From 1903 to 1904, a three-winged castle was built in the Neo-Renaissance style. Today Krickenbeck is a conference center.
