All that remains of the former Strijen Castle is a single tower fragment of seven storeys high. The building of Strijen Castle probably started in 1288 by Willem Willemszoon van Strijen. Strangely enough the bailey was situated on the territory of the County of Holland and the castle itself on the territory of the Duchy of Brabant. In 1324 the castle was bought by Willem van Duivenvoorde who reinforced and renovated it. When he died the castle became property of his half-brother Jan van Polanen.
In 1573, during the 80-Years war, the castle was destroyed after a siege by Spanish troops. It was never rebuild and fell into decay. In the next centuries the castle ruin was used as a quarry for stones which were used to repair roads and a church in and around the village of Oosterhout.
References:The Château de Chantilly comprises two attached buildings: the Petit Château built around 1560 for Anne de Montmorency, and the Grand Château, which was destroyed during the French Revolution and rebuilt in the 1870s. Owned by the Institut de France, the château houses the Musée Condé. It is one of the finest art galleries in France and is open to the public.
The estate"s connection with the Montmorency family began in 1484. The first mansion (now replaced by the Grand Château) was built in 1528–1531 for the Constable Anne de Montmorency by Pierre Chambiges. The Petit Château was also built for him, around 1560, probably by Jean Bullant. In 1632, after the death of Henri II, it passed to the Grand Condé who inherited it through his mother, Charlotte Marguerite de Montmorency.
Several interesting pieces of history are associated with the château during the 17th century.
