Imagine a medieval castle that seems to float on the surface of the water. Surrounded by a shimmering moat, with its tall red-brick towers, it looks like a film set. Yet Château d’Olhain, one of the most beautiful medieval castles in northern France, is very real.
Located around two hours from Brussels, on the banks of the Lawe at Fresnicourt-le-Dolmen, this incredibly well-preserved fortress transports you back in time. Between lush greenery, historical accounts and postcard-perfect views, this getaway near Belgium promises a complete change of scenery.
A medieval getaway just 2 hours from Brussels
It’s hard to imagine that this castle, so peaceful today, has witnessed more than eight centuries of history. Olhain’s first fortification appeared as early as 1179, under the impetus of the powerful d’Olhain family, one of the oldest lineages of the Artois region. A century later, Hugues d’Olhain, a knight who had taken part in the Crusades, had a sandstone fortress built to protect his lands.

But it was from 1407 onwards that the castle took on its present form, with towers, walls and drawbridge. Remaining in the same family for over 450 years, it has seen knights, dukes and even a few battles before becoming the peaceful place we visit today. During your visit, you’ll be able to admire the chapel, vaulted cellars and dungeon floors that bear witness to this rich history.
A castle that seems to float on water
Built on a small island surrounded by a deep moat, Château d’Olhain truly gives the impression of floating on a lake. At sunrise or sunset, the towers are perfectly reflected in the calm water. This unreal setting is reminiscent of Miyazaki’s world, halfway between Chihiro’s Journey and The Moving Castle.

Visit the nature park around Château d’Olhain
Château d’Olhain is of course the star of this escapade. However, if you make your way there, the region has plenty of other surprises in store. The Olhain estate lies at the heart of Parc d’Olhain. This is a vast 400-hectare wooded natural area, where you can easily spend a whole day enjoying the great outdoors. After exploring the ancient stones of the château, take a stroll through the undergrowth. You can also take a break by the pond, or even enjoy a picnic with a view of the red towers reflected in the water.
For the more active, the park offers a range of activities. Thrill-seekers will appreciate the tree climbing and mountain bike trails. There are also signposted walks, a swimming pool and mini-golf for the whole family. What’s more, if you’re traveling with children, there’s a large play area dedicated to them, enough to keep them occupied while you take a breather on a bench in the sun.
Near the playground, the Parc d’Olhain Belvedere offers a magnificent 360-degree view of the site, from a height of 210 metres.

And for history buffs, the region has plenty of other medieval sites to visit: the charming towns of Arras and Béthune are only a twenty-minute drive away, with their magnificent Flemish squares, belfries and museums.
