Ravengiersburg Augustinian Canonical Foundation was founed in 1074 on the site of the Salian castle of the Counts in the Trechirgau. In the document dealing with land donations to the monastery, the name Hunsruche – Hunsrück – is mentioned for the first time.
The heyday of the monastery was during the 14th and 15th centuries. During this time, the monastery developed into one of the largest ruling estates in the entire region, whose possessions reached from the Nahe to the Mosel Rivers. The glory ended in the turmoil of the Reformation and the Thirty Years War, and from there began a varied and painful history that ended in the year 1631 with the almost complete destruction of the monastery and its church. However, Augustinian monks were still in charge there until secularization in the year 1803.
Today the St. Christophorus-Kirche has a Romanesque twin-tower façade. This imposing church is also called the Hunsrückdom (“Hunsrück Cathedral”), although it is not actually a cathedral.
The integrity and compactness of the architecture of the church makes it one of the most important structures of the 12th and 13th centuries between the Nahe, Mosel and the Middle Rhine River. The originally Romanesque church was erected around 1160 and must have been a three-nave basilica. It had approximately the same length as today's church and was attached to the double tower of the west works. Under the chancel section a four-nave Romanesque crypt with three apses from the first half of the 12th century was found. A disastrous fire, however, destroyed the Romanesque basilica around 1440. The new building was completed in the year 1497, probably a three-nave basilica in the Gothic style, nothing of which remained after its destruction by Swedish troops in 1631. The rebuilding from 1718-1722 was undertaken by Elector Carl Philippe upon the old foundations of the church using the available stone.
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.
