Ooidonk Castle is the residence of the current Count t'Kint de Roodenbeke. A fortress was first built on the site of the present castle in 1230, intended to defend the city of Ghent and to fortify the river Leie. This fortress was owned by Nikolaas van Hoendunc, lord of Nevele.
After it was destroyed by Louis de Male, count of Flanders, Jean de Fosseux rebuilt and enlarged the fortress from 1381 onwards, adding moats, so that the castle could only be reached by drawbridge, and strengthening the defences with four towers.
In the 15th century the castle came into the possession of the well-known French noble family of Montmorency, when Jeanne de Fosseux married Jean de Montmorency.
In 1526 Philippe II de Montmorency-Nivelle, the well-known rebel, son of Joseph de Montmorency, Seigneur de Nivelle (died 1530) and of Anna of Egmond, was probably born at Ooidonk Castle. After the death of his father, his mother married Count Jan van Hoorn, who adopted her children. Philippe thus became known as Count Hoorn. He opposed the Spanish rule in the Netherlands and was finally decapitated in 1568 in Brussels.
In the turmoil of religious wars the castle was destroyed twice, in 1491 and in 1579. After the fire of 1579 it was rebuilt again, and this building survives as the present castle.
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.
