Discover the vast underground labyrinth of Fort Eben-Emael, learn about the daring glider attack that changed history, and find out what you can explore today.
A fortress like no other
On the banks of the Albert Canal, just outside the village of Ében-Émael, stands a fortress that was once hailed as the strongest in Europe. Built between 1931 and 1935, Fort Eben-Emael was designed to stop any German advance into Belgium. Its massive underground galleries, reinforced bunkers, and heavy artillery earned it the reputation of being “impregnable.” At nearly a square kilometre in size, it was the largest fortress in the world at the time.
Yet on 10 May 1940, in the early hours of the German invasion of Belgium, Fort Eben-Emael became the stage for one of the most daring and innovative military operations in history.
The attack that shocked the world
Just before dawn, 10 German gliders swooped silently onto the fort’s plateau. Onboard were only 85 specially trained paratroopers. Using newly developed explosives known as shaped charges, they quickly disabled the fort’s gun turrets, bunkers, and observation posts. Despite being defended by over 1,200 Belgian troops, the fortress was overwhelmed. Within 24 hours, its defences were neutralised. By noon on 11 May 1940, Fort Eben-Emael surrendered. This glider assault was the first of its kind in world history. It cleared the way for German forces to cross the Albert Canal and pour into Belgium. It remains a landmark moment in the development of modern airborne warfare.
Key aspects of the invasion of Fort Eben-Emael
- Glider assault: German forces used DFS 230 troop-carrying gliders, a new tactic for depositing infantry directly onto the fort’s roof.
- Shape charges: Elite soldiers used new hollow shape-charge explosives to destroy the fort’s gun positions, a revolutionary use of explosives against concrete and steel fortifications.
- Strategic importance: The fort’s capture was a critical first step in the German invasion of Belgium, clearing the path for the advance into France.
- Unexpected tactics: The “Silent Blitzkrieg” of Eben-Emael was a completely new and surprising tactic that caught the Belgian forces off guard, demonstrating the effectiveness of combined air and ground operations.
What to see in Fort Eben-Emael
I chose a self-guided visit to explore the impressive underground military complex of Fort Eben-Emael. I followed the fixed route through the underground barracks, the museum, the infirmary, and a limited part of the 5-kilometer-long tunnel system on the middle floor. I could see for myself the effects of a “shaped charge” explosion and watched a fascinating 15-minute film that provided valuable insight into the fort’s structure, history, and of course the attack on May 10, 1940.
A guided tour is also available. It will take you further into the galleries, introducing you to the combat bunkers, the gun room of an artillery casemate (the fortified chamber from which guns were fired), and the command post. The guided tour lasts 2 hours.
Much of Fort Eben-Emael lies deep underground, cut into a marlstone hill. Its three levels stretch across 5 km of tunnels, housing barracks, workshops, kitchens, a hospital, a power station, and ammunition stores.
Walking through these galleries, I got a clear glimpse of how the garrison lived. Officers’ quarters, a restored operating theatre, and even the old decontamination rooms are preserved. Standing in these spaces, I found it easy to imagine the tension of those days in May 1940.
One of the highlights of my visit was the sight of the DFS 230 assault glider. Only two survive worldwide, and the one at Eben-Emael has been carefully reconstructed from original parts. It serves as a poignant reminder of the bold airborne raid that changed the course of the fortress – and the war.
Exploring the plateau
Above ground, I enjoyed checking out the 45-hectare plateau that gave wonderful views over the Albert Canal and the Meuse valley towards Maastricht. This was the landing site of the German gliders, and I followed well-signed walking paths past bunkers that still bear the scars of battle. You can pick up a map and route guide from the front desk at the fort.
Is Fort Eben-Emael worth visiting?
Most definitely! Whether you’re fascinated by military history, curious about underground engineering, or simply want to enjoy the panoramic views from the plateau, Fort Eben-Emael is one of Belgium’s most remarkable heritage sites. It’s well laid out, there’s plenty to see, and at 17 EUR for a 2-hour guided visit, I think it’s good value.

Where to visit and stay nearby
The Tower of Eben-Ezer is also in Bassenge and well worth a visit, as you will see if you read my account of when I spent a morning there a few years ago. Why not visit both on the same day?
Alternatively, you could stay overnight in the area, take your time visiting both places, and combine with a lovely country walk in the neighbourhood, such as this one which I did after visiting the Tower of Eben-Ezer. Here’s some excellent places to stay locally:
- Rue Haute by M&M, 71 Rue Haute, 4690 Eben-Emael: “Amazing hosts, absolutely delicious breakfast and nice facilities altogether! We totally loved it here!”
- B&B Hostellerie Marie, Rue de L’ Aumont, 4690 Eben-Emael: “The room is super charming, the breakfast was wonderful, Clementine (the owner) was super helpful on providing us with tips about the region.”
- B&B 4 Seasons, Waterstraat 46, 3770 Riemst: “It is gorgeous, the rooms are so big and comfortable, they have a really nice shower and a huge bathtub. The staff was lovely and attentive.”
- B&B Domaine Villa Bayard, Rue de la Vallee 89, 4690 Kanne: “Wonderful villa on the border of the Belgium. The owners are super friendly. The rooms and the common area is really comfy.”

Frequently Asked Questions about Fort Eben-Emael
Why did Fort Eben-Emael fall so quickly?
Because the German paratroopers used a completely new type of explosive — the shaped charge — which disabled the fort’s gun turrets and bunkers within hours. Combined with the surprise glider landing, this made resistance almost impossible.
How big is the underground tunnel system?
The galleries stretch for more than 5 km, connecting barracks, workshops, the hospital, and ammunition stores. Walking through them today gives a powerful sense of the fort’s vast scale.
Can you visit the plateau independently?
Yes. The 45-hectare plateau is still military land, but visitors are allowed provided they stay on the marked paths. Guided tours sometimes include stories of the glider landings and bunkers.
How does Fort Eben-Emael compare to other Belgian forts?
It was the largest and most modern fortress of its time, but unlike older forts around Liège or Namur, Eben-Emael was designed with stronger artillery and better underground facilities. Its dramatic fall in May 1940 made it unique in military history.
I created Discovering Belgium in 2011 to share the country’s hidden stories, fascinating places, and remarkable people. Through articles, photography, and audio walks, I share discoveries that reveal Belgium beyond the obvious. Hope you enjoy this site.
A fascinating story.
