History and restoration of Pierrefonds Castle
Pierrefonds: the ruined fortress Napoléon III had Eugène Viollet-le-Duc reinvent
Built in 1397 by Louis of Orléans and dismantled in the 17th century, Pierrefonds Castle was little more than a romantic ruin when Napoléon III entrusted its rebirth to Viollet-le-Duc. The result? An extraordinary reinvention of the Middle Ages.

With its eight towers and massive keep towering over the River Oise, Pierrefonds Castle appears to be an intact medieval fortress. Yet what we see today owes almost everything to the 19th century: a spectacular reconstruction, commissioned by Napoléon III and executed by architect Eugène Viollet-le-Duc, who never hid the fact that he had largely reinvented the building.
01
A fortress built in less than ten years
Pierrefonds Castle was completed in 1397 in less than a decade at the behest of Louis of Orléans, son of King Charles V and younger brother of Charles VI. Having received the County of Valois as an appanage, he made Pierrefonds—as well as the castles of Coucy and La Ferté-Milon, which he also commissioned—a strategic stronghold designed to protect Paris from Burgundian and English incursions during the Hundred Years' War.

Dismantled by Louis XIII, reduced to a romantic ruin
The castle was dismantled in 1617 on the orders of Louis XIII and remained in a state of ruin for nearly two centuries. 19th-century Romantic artists seized upon it as a source of inspiration, with the castle notably featured in the 1839 *Voyages pittoresques et romantiques dans l'ancienne France*. In 1810, Napoléon I purchased the site but did not undertake any work.

Napoléon III entrusts the project to Viollet-le-Duc
It was his nephew Napoléon III, who frequently stayed in nearby Compiègne, who decided to revive the castle. On the advice of Prosper Mérimée, he commissioned architect Eugène Viollet-le-Duc to restore it between 1857 and 1858. The initial plan, limited to shoring up the keep and two towers to preserve a 'picturesque ruin', was abandoned by 1861 in favour of a far more ambitious project: to transform Pierrefonds into a complete imperial residence.

A reconstruction openly embraced as a reinvention
Viollet-le-Duc did not shy away from his approach: restoring a building, he wrote in 1866, is 'to restore it to a complete state that may never have existed at any given time'. At Pierrefonds, he combined precise archaeological knowledge of 15th-century military architecture with cutting-edge construction techniques for his era, while personally designing most of the interior decor and furnishings. Upon his death in 1879, his son-in-law, architect Ouradou, took over the project, which was halted in 1885. Classified as a historic monument in 1862, the castle is now managed by the Centre des monuments nationaux.
