The quarry system is known as 'Wellington' because many of the tunnels were named after streets in New Zealand by the New Zealand Tunnelling Company that developed them.
The tunnels were connected to the front lines by an elaborate system of light-rail tracks and tunnels that moved troops entirely underground.
The temperature inside the tunnels remains a constant 9 degrees Celsius year-round regardless of surface weather.
Archaeologists recovered thousands of artifacts including personal items, tools, and equipment discarded by soldiers during the rapid 1917 advance.
The site was largely forgotten for decades until local researchers began mapping and restoring the tunnels in the early 2000s.
Carrière Wellington is a network of underground chalk quarries in Arras, France, repurposed by Allied forces as a secret barracks and staging area during the Battle of Arras in April 1917. The site allowed thousands of soldiers to hide and prepare for a surprise offensive against German lines. Visitors descend 20 meters underground via a glass elevator into tunnels that were originally medieval chalk extraction sites. The tour route includes preserved living quarters, medical stations, and graffiti left by soldiers awaiting the attack. The site remains a focal point for understanding the tactical engineering of WWI trench warfare.
The entrance area where the industrial modern architecture contrasts with the ancient chalk quarry walls.
Bring a warm sweater or jacket even in summer due to the consistent low temperature underground.
Wear comfortable, flat walking shoes with good grip, as the tunnel floors can be uneven or damp.
Book your entry slot in advance online, as the number of visitors per guided tour is strictly limited.
Do not attempt to explore beyond the guided path, as the wider quarry network remains structurally unstable in many sections.
Closed annually for a brief period in early January; otherwise open daily, though guided tours may be subject to seasonal demand.
Maintain a respectful, quiet demeanor; touching the tunnel walls is strictly prohibited to preserve historical markings.
