Some 14 kilometres away, the castle, which looks like a fairy tale, magically appears on the road leading to Compiègne.  
 
This fortress, built at the end of the 14th century for Louis de Valois, brother of Charles VI, suffered its first devastating siege at the beginning of the 17th century. On Richelieu's orders, this den of the nobility hostile to the cardinal's policy was dismantled. For two centuries, it had an edentulous silhouette, the result of the meticulous destruction of its defensive system.
 
At the beginning of the 19th century, Romanticism found the charm of the ruins and the memory of the Gothic splendour. Napoleon III, as a Compiègne neighbour, fell in love with the place and commissioned Eugène Viollet-le-Duc (1814-1879) to restore it in 1857. The architect of the great national restorations was at the end of a glorious career that was to establish his authority deeply in the French architectural tradition. Nevertheless, it was as a young man that he approached this site where he led a final demonstration of modern architecture.

Climbing to the tree, an adventurous and acrobatic course, hung on hundred-year-old oaks. A few kilometres from Pierrefonds, in the Compiègne national forest.
