There is something quietly magical about sleeping in a medieval castle and waking up to the forests of the Ardennes outside your window. But what if, one morning, you could step out of your own château and ride straight into the Middle Ages?
Every year, the French Ardennes hosts some of Europe's finest medieval festivals — two-day spectacles of knightly combat, fire shows, artisan markets, and living history that bring the region's extraordinary castle heritage back to life. For guests staying at Château Guillermo, a private castle rental near Sedan, these festivals are not just day trips. They are a natural extension of the atmosphere you are already living.
Here are the best medieval festivals in the Ardennes in 2026, organised by date so you can plan your stay around them.
1. Sedan Medieval Festival 2026 — Europe's Largest Castle, 10 Minutes Away
Data: 16–17 mei 2026
If there is one medieval festival in the Ardennes that needs no convincing, it is this one.
The Château Fort de Sedan is the largest medieval fortress in Europe — 35,000 square metres of fortified stone, built in the 15th century, towering over the Meuse valley. Every May, it hosts one of the most celebrated medieval festivals in France, drawing over 40,000 visitors across a single weekend. The 29th edition takes place on 16 and 17 May 2026.
What awaits: more than 100 artisans, historical re-enactment troupes, and performers taking over the fortress entirely. Knightly combat in full armour in the castle moat. Fire shows, falconry demonstrations, archery, juggling, street theatre, and a grand medieval market where potters, weavers, tanners, and illuminators sell their craft. On Saturday evening, the day ends with a torchlit procession and fireworks above the ramparts.
For families, there are children's workshops in crossbow, fencing, and calligraphy. For the group, there is an entire medieval village to wander and get delightfully lost in.
We have written about a Halloween night at Sedan Castle from the perspective of our guests — worth reading to get a sense of the place outside festival season. In May, it is something else entirely.
From Château Guillermo, Sedan is roughly 10 minutes by car.
Tickets: From €9/adult (presale), free for children under 8 More info: chateau-fort-sedan.fr
2. Medieval Weekend La Roche-en-Ardenne — A Town That Steps into the Past
Data: 25–26 juli 2026
La Roche-en-Ardenne has a talent for atmosphere. The ruined castle sits dramatically above the town, and the Ourthe river curls through it like a scene from an illustrated manuscript. During its annual medieval weekend, organised in collaboration with the Compagnie de la Licorne, both castle and town lean fully into the illusion. Compagnie de la Licorne — gaan zowel kasteel als stad volledig mee in de illusie.
On the programme: medieval combat, live music, exhibitions, a falconry show, a craft market, and a medieval banquet. The kind where you eat with your hands, the musicians do not stop, and someone inevitably declares themselves the rightful heir to something.
A festival that rewards those who arrive ready to participate, not simply observe.

3. Vianden Medieval Festival 2026 — Nine Days at a Luxembourg Castle
Data: 25 juli – 2 augustus 2026, dagelijks 10:00–19:00
For groups willing to make a slightly longer excursion, the Château de Vianden in Luxembourg is extraordinary.
One of the most beautifully restored medieval castles in Europe, Vianden hosts its festival across a full nine days — unusual for an event of this kind, and deeply generous. Knight encampments, fire and combat shows, acrobats, minstrels, birds of prey in flight, historical music, and a medieval artisan market that grows richer with each day.
The castle itself is worth the drive. Perched above the Our valley, it has the kind of silhouette that makes you stop the car and reach for your camera before you even intend to.

4. Medieval Festival Bouillon 2026 — 38 Editions at the Castle of the Crusaders
Data: 8–9 augustus 2026
Bouillon holds a particular significance in the history of the Crusades. It was from here that Godfrey of Bouillon set out in 1096 to lead the First Crusade. The Château de Bouillon, carved into a rocky spur above the Semois river, carries that weight in every stone.
The summer festival, now in its 38th edition, honours that heritage with a programme that is both festive and genuinely educational. Dozens of artisans recreate medieval trades — costumes, mead, leatherwork, ceramics — alongside knightly tournaments, a medieval camp, street performances, falconry animations, and processions through the castle grounds.
Bouillon is a town worth building a full day around. The Visit Ardenne regional guide is a good starting point for planning an itinerary around the festival. regionale gids van Visit Ardenne is een goed vertrekpunt om een dagprogramma rond het festival op te bouwen.
5. Les Hubertoises Saint-Hubert — Where the Ardennes Meets Legend
Data: 5–6 september 2026 (te bevestigen)
Saint-Hubert sits deep in the Ardennes forest, in a silence that feels deliberate. The town is built around the legend of Hubert — a nobleman who, according to tradition, encountered a stag bearing a golden cross between its antlers on Good Friday and renounced his life of privilege on the spot.
Les Hubertoises brings this story back to life through historical theatre, a high mass with horn players, the blessing of the animals, an international dog show, and a medieval village around the basilica. It is not a festival of combat and fire — it is something quieter and more unusual. A celebration of transformation, of nature, and of one of the Ardennes' most enduring myths.
For groups who want something different after the tournaments and banquets, this is it.

Tips for Making the Most of a Medieval Festival Weekend in the Ardennes
The Ardennes rewards guests who plan ahead. A few things worth knowing before you go:
Arrive early — especially at Sedan, where the encampments fill up quickly in the morning and the queues at the gate grow fast after 11am. For families with children, Sedan and Bouillon are particularly well set up with dedicated workshops and activities for younger visitors.
Between festivals, the region has no shortage of things to do in the French Ardennes. From forest trails and river kayaking to historic citadels and local breweries, there is enough to fill several days comfortably.

Live the Story, Not Just Visit It
There is a particular pleasure in attending a medieval festival in the Ardennes and then returning to your own castle for the evening.
At Château Guillermo, the stone walls are real, the history is present in every room, and the grounds — four hectares of private park, campfire, hot tub steaming under the stars — invite the kind of unhurried evenings that belong to another era. The château was originally built in 1834 by Count de Viry as a rural retreat for pleasure and hunting. His portrait still hangs on the wall.
Plan your French Ardennes stay around a festival weekend and you will leave with the kind of memories that are genuinely difficult to explain to people who were not there.
