The Abbey of Saint-Gildas is dedicated to St. Gildas (c. 500–570) who was a British historian and cleric. He is one of the best-documented figures of the Christian church in the British Isles during this period. According a legend Gildas established the abbey, but there are no written evidences. Buildings were destroyed by Norman raids in the 10th century.
The first known record dates from 1008 when the abbey was restored by the order of Geoffrey I of Bretagne. The new inauguration was held in 1032. The heyday of Saint-Gildas Abbey was in the 11th-14th centuries. During the Hundred Years' War most of the archives were destroyed. The monastery started to decay in the 16th century. The nave of the church collapsed in 1668 when a lightning hit it.
the next restoration took place in the late 1600s. The abbey church was moved as a parish church during the Great Revolution in 1796.

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.
