The FT3 combat shelter was built in 1906 on the right bank of the Meuse River as part of the Verdun fortress system, designed to house 100 infantry soldiers. During the Battle of Verdun in 1916, it was converted into a command post (PC118) and changed hands multiple times between French and German forces. The shelter was heavily damaged by French artillery when occupied by German troops, particularly on its vulnerable masonry facade facing Verdun, rendering it unusable.

The Abri-Caverne de Douaumont was an underground shelter for French troops during the Battle of Verdun. Carved into the limestone bedrock, this shelter offered protection from artillery fire and served as a rest and assembly point close to the front line. Strategically located near Fort de Douaumont, it played a crucial role in supplying and sheltering soldiers during the fiercest fighting of 1916.

Abri is forbidden access. Still, it gives an impression of what war violence can do.

A special location that is forbidden to enter. You can only take a look into the tunnel complex at the first meters.

This bunker facility is certainly not a risk-free area... bringing your own light source is an absolutely sensible thought

The "caves" around Douaumont are primarily significant underground military fortifications and shelters from World War I, rather than natural geological formations. These sites offer a unique and poignant glimpse into the subterranean warfare and living conditions of soldiers during the Battle of Verdun. You will find extensive networks of tunnels, bunkers, and command posts.
Among the most significant sites is Fort Douaumont, a massive WWI fortification with two subterranean levels, barracks, and firing positions. It's a powerful memorial to the Battle of Verdun and is inscribed on the UNESCO World Heritage List. Other notable sites include the Douaumont Cave Shelter and the Combat Shelter - PC 118.
While the region is predominantly known for its historical military underground structures, there are some natural rock formations. The Gibet Caves, located along a side channel of the Meuse, are an example of natural caves in the area. However, access can be challenging, especially for cyclists.
Many of the historical sites, such as Combat Shelter - PC 118 and Abri DV3 (Fort de Vaux Shelter), are rated as challenging due to their nature. Some areas may have restricted access or require caution, and a light source is often recommended. Always check specific site conditions before visiting.
While the historical sites offer profound educational value, some are not ideal for young children due to safety concerns or the solemn nature of the memorials. For instance, Abri DV3 (Fort de Vaux Shelter) is noted as potentially dangerous with shafts, and supervision is advised if children are present. The Douaumont Cave Shelter might be more accessible for families interested in history.
Some of the historical underground structures now serve as habitats for wildlife. For example, the Combat Shelter - PC 118 is a summer roost for a large colony of bats, which should not be disturbed by visitors. Other overgrown bunkers and dugouts throughout the woods may also host various species.
The region around Douaumont offers various outdoor activities, particularly cycling and gravel biking. You can explore routes like the 'Quadrilatère des Forts' or the 'Douaumont Ossuary – Verdun Memorial loop'. For more options, check out the Gravel biking around Douaumont guide or the Cycling around Douaumont guide.
Even in summer, underground sites can be cool and damp, so it's advisable to wear layers. Sturdy footwear is recommended as surfaces can be uneven. For sites with restricted lighting, bringing your own light source, such as a flashlight or headlamp, is highly recommended.
Exploring major sites like Fort Douaumont can take several hours due to its extensive size and historical significance. Smaller shelters like the Douaumont Cave Shelter might require less time, but allow for reflection on their historical context. Plan accordingly based on the number of sites you wish to visit.
Beyond the main attractions, the woods surrounding Douaumont and Vaux contain numerous other overgrown bunkers and dugouts from WWI. While many are largely collapsed or unstable and access may be forbidden, they hint at the extensive subterranean networks created during the war. The Intermediate Depot Under Rock offers a glimpse into a tunnel complex, though access is restricted to the initial meters.
Visitors are deeply moved by the historical significance and the tangible connection to World War I. They appreciate the opportunity to witness the immense scale of military engineering and gain a profound understanding of the conditions faced by soldiers. The sites serve as powerful memorials, evoking a strong sense of remembrance.
