Beasts & Witches – Dossier No. 01
Ghosts of the Fortresses
Towers, ramparts, underground passages… In Moselle, ancient stones sometimes have many stories to tell.
At Halloween, from Malbrouck Castle to the walls of the Thionville museum, some places take on a completely different atmosphere. It is time to discover what is lurking there.
Step into the story
Several Beasts & Witches events invite you to discover these places in a completely different light. Haunted castles, treasure hunts, night-time experiences or immersive adventures for the bravest visitors: each offers its own way to send a shiver down your spine.
Explore them at your own pace, keep your eyes open… some details may well surprise you.
From 17 to 29 October 2026 | Malbrouck Castle
A life-size haunted castle
Start by stepping through the gates of Malbrouck
Four towers, inner courtyards, a succession of rooms and passageways where you never quite know what is waiting behind the next door: Malbrouck already has the perfect setting for Halloween.
During Beasts & Witches, the fortress is transformed, taking visitors of all ages on a journey through a haunted castle. Legends take over the towers and corridors, while spaces usually dedicated to exploring the castle become the setting for an experience designed to gradually build the suspense.
The experience remains suitable for the whole family: a great way to start before moving on to something a little more intense.
A detail to remember
How many towers does Malbrouck Castle have?
No need to look up the answer on your phone. Once you are there, simply look up.
A change of scenery
In Thionville, choose your experience
Here, the level of fright depends on your age… and the time of day.
For younger visitors, The Forgotten Ancestor turns a visit to the museum into a treasure hunt. A character has vanished from the memory of the place: their identity has been erased, along with their story. Visitors are invited to look at the collections in a different way, spot the details that matter and gather enough clues to understand who this person was.
But on 30 October, the experience continues after dark. From 7 pm to 11 pm, the special Halloween evening is aimed at visitors aged 10 and over. The same world, the same walls… but a very different atmosphere once night falls over the museum.
Only one question matters
Who is the Forgotten Ancestor?
We are not going to give you that answer. You will have to find it for yourself!
31 October 2026 | U4 Blast Furnace Park | Uckange
Night of Fire
Still with us? Then get ready for even bigger thrills!
Leave the family-friendly activities behind.
At the heart of the U4 Blast Furnace, Night of Fire offers a 90-minute collective immersive experience for visitors aged 16 and over. The industrial setting is much more than a backdrop: steel, darkness, monumental structures and remnants of the site all play a part in what awaits you.
Here, no one is promising you a simple Halloween-themed walk. You will be watched, put to the test, faced with choices and drawn into a story in which the “Towers” are searching for their chosen one.
For 90 minutes, you will move forward without knowing exactly what the experience has in store for you. Departures take place every ten minutes, from 6 pm to 11 pm, by reservation only.
Before you enter
You will not be chased or attacked.
But you will be watched, put to the test and faced with choices.
The real question is: how far are you prepared to go?
Still looking for more thrills?
Malbrouck, Thionville and Uckange are just a few of the highlights of the 2026 edition.
Treasure hunts, shows, family activities, night-time experiences or events for the bravest visitors: there are many different ways to experience Beasts & Witches across Moselle.
Now it is up to you to plan the rest of your programme according to your age, your interests… and how much of a fright you can handle.
