Pierrefonds as Camelot
Pierrefonds is best known to a generation of viewers as Camelot, the seat of King Arthur in the BBC's Merlin. Here is what's documented about the castle's part in the series, and where else the production filmed.
Château de Pierrefonds and the Merlin filming locations →-
Series one, 2008
Camelot is cast
Merlin went into production in March 2008, filming in Wales and in France at the Château de Pierrefonds, which became the castle of Camelot.
-
The towers and roofs
The silhouette on screen
The round towers and steep conical roofs that define the castle's skyline are what read as Camelot — the storybook completeness Viollet-le-Duc built from 1857 suited a series that needed a fortress to look whole at a glance.
-
Series five, 2012
Back for the final series
Filming for the fifth and final series began in March 2012, in Pierrefonds and near Cardiff; the show ended with a two-part finale at Christmas 2012.

Other locations
Not everything was shot here
The production also filmed in Wales, and the first series used Penshurst Place and Chislehurst Caves in Kent. What you see inside Pierrefonds today is Viollet-le-Duc's nineteenth-century decoration, not anything built for the series.

Beyond Merlin
A long film career
Pierrefonds has also appeared in Les Visiteurs, Highlander: The Series, The Messenger: The Story of Joan of Arc, The Man in the Iron Mask (1998) and the series Versailles, filmed here in 2017.
- Merlin also filmed in Wales and, for its first series, in Kent — so not every Camelot scene was shot at Pierrefonds.
A castle built twice
A fortress, then a ruin, then an invention
Louis I, Duke of Orléans and brother of Charles VI, received Pierrefonds in 1392 and had it rebuilt as a towered fortress through the 1390s until his death in 1407, on a site that had carried a castle since the twelfth century. In 1617 royal troops sent by Cardinal Richelieu besieged and took it, and its demolition began — but was never finished, which is why a romantic ruin survived until Napoleon I bought the site in the 1810s for under 3,000 francs.
Viollet-le-Duc's idea of the Middle Ages
In 1857, on Prosper Mérimée's advice, Napoleon III asked Eugène Viollet-le-Duc — the restorer then also working on Notre-Dame de Paris and Carcassonne's walls — to restore Pierrefonds. In the early 1860s the brief widened from repairing the keep to a complete imperial residence, at a cost of some five million francs. What resulted was less a restoration than an invention: painted halls and sculpted figures dressing the castle as the nineteenth century imagined the Middle Ages, over an exterior that follows 14th-century military architecture closely.
Why rooms open on rotation
Conservation work continues in sections, so which interiors are open can shift between visits. The Empress's Apartments, created for Napoleon III's residence, opened to visitors in May 2026; the Salle des Preuses is closed for a second phase of restoration. Treat any single room as part of the day's programme rather than a permanent fixture.
Unfinished on purpose? No — the money ran out
Work went on after Viollet-le-Duc's death in 1879 under his successors, but it stopped for good in 1885. With the Second Empire gone, the reconstruction lost its patron and its funding, and some of the interior decoration was never completed.

Questions visitors ask
Is Château de Pierrefonds the Camelot from Merlin?
Yes. The BBC's Merlin used the castle as Camelot: the series went into production in March 2008 with filming at Pierrefonds, and filming for the fifth and final series began there in March 2012. The production also filmed in Wales and Kent, so not every Camelot scene was shot here.
What is there to see inside Château de Pierrefonds?
Curtain walls and round towers, the inner courtyard, and state rooms that Viollet-le-Duc dressed with painted decoration and sculpted figures for Napoleon III, including the Empress's Apartments, opened to visitors in May 2026. Which individual rooms are open varies with ongoing conservation work.
How do I get from Paris to Château de Pierrefonds?
By car it's about 1 hour 15 minutes via the A1 autoroute (exit 9) and Compiègne. By public transport, take a train from Paris Gare du Nord to Compiègne, then a local bus or a taxi for the final 15 kilometres or so — there is no station at Pierrefonds itself.
Is Château de Pierrefonds a UNESCO World Heritage Site?
No. It was classified as a monument historique on the 1862 list and is a landmark of nineteenth-century Gothic Revival restoration, but it does not carry UNESCO World Heritage status.
How much time does a visit take?
Budget roughly 1.5 to 2 hours for the towers, rampart walk, courtyard and state interiors without rushing. Stepping outside afterwards to the village, the lake at the castle's foot and the Forest of Compiègne — all free — easily stretches the day further.
When is the best time to visit?
Arriving soon after opening, on a weekday outside French school holidays, gives the quietest courtyard and the clearest light for photographs. The castle opens every day bar a handful of holidays, with seasonal hours listed on its own website.
Is the castle suitable for children, and is it stroller-friendly?
It suits children well — real towers, a rampart walk and carved figures to spot — but pushchairs aren't allowed inside the castle; they can be left in the main courtyard, so a baby carrier is easier on the spiral stairs and uneven historic floors.
Is Château de Pierrefonds accessible for visitors with limited mobility?
Partly. There's a drop-off point and two reserved parking spaces for visitors with reduced mobility on the esplanade, and folding cane seats are offered at the start of the visit, but the towers, rampart walk and some interiors involve spiral stairs and uneven historic floors that aren't step-free.
