Château de Pierrefonds

Pierrefonds looks unusually complete because it was heavily reinvented in the 19th century by Eugène Viollet-le-Duc. The rebuilding was commissioned under Napoleon III and began in 1857.

Yes, the BBC series Merlin used Château de Pierrefonds as the exterior for Camelot. That TV connection is one reason many visitors recognize the castle even before knowing its French history.

The official visitor route highlights the courtyard of honor, chapel, bridges, park, and the recumbent figures display. Current Centre des monuments nationaux information lists regular entry at 9 euros.

It is both: the site began as a medieval castle, but the version visitors see is strongly shaped by Viollet-le-Duc's 19th-century restoration. That makes it important for understanding both medieval fortification and Romantic-era ideas of the Middle Ages.
