Ribaucourt castle was built originally in the 12th century, but it was just a fortitied wooden tower. The lords of Perk expanded the castle and it was in possession of several South Brabant noble families. During the French occupation in 1809 the French officer Pieter Bounder of Melsbroek bought the castle. He sold the castle in 1833 to Count Prosper Christyn de Ribaucourt, senator of Dendermonde. The current Count Daniƫl de Ribaucourt is still Lord of Perk.
The castle is considered as one of the most beautiful of the Brussels area. It counts more than 200 rooms and was modernized by it owners throughout the centuries. The current castle largely dates back to the 17th, 18 and 19th century. The park is 90ha and consists of meadows, forest and ponds. It is a real nature and bird sanctuary.
The castle is private domain but you can view it from the public road and on rare locations there are walks organized in the park.
References:Sigmaringen Castle was first mentioned in the year 1077 in the chronicles of Petershausen monastery. The oldest parts of the castle are concealed beneath the alterations made during the 17th and the 19th centuries. The secret of the earliest settlement built on this defendable rock will never be fully revealed: large-scale excavation work would be necessary, which the extensive land development renders impossible. Judging from the many Roman remains unearthed in the area around Sigmaringen, the 12th century keep known as the 'Roman Tower' could be traced back to a Roman predecessor.
The castle remains that have been preserved (gate, great hall and keep) date back to the Staufer period around 1200. The castle remains were integrated into subsequent buildings. The foundations of the castle buildings are to a large extent identical to the surrounding castle wall.
These remains give us a good idea of how the castle might have looked during the 12th century.
