Carrière Wellington is a museum in Arras, northern France. It is the name of a former underground quarry that was part of a network of tunnels used by the British and Commonwealth Empire during World War I. Opened in March 2008, the museum commemorates the soldiers who built the tunnels and fought in the battle of Arras in 1917. From the Middle Ages to the nineteenth century, the plaster beds under Arras were extensively quarried to provide stone for the city's buildings. The quarries have fallen into disuse since the beginning of the 20th century. In 1916, during the First World War, British forces controlling Arras decided to reuse the underground quarries to help with a planned offensive against the Germans whose trenches crossed what are now the eastern suburbs of the city. The quarries had to be linked so that they could be used as shelters from incessant German battles and as a means of transporting troops forward in secrecy and security. 500 miners of the New Zealand Tunneling Company, including Maori and Pacific Islanders, recruited from the country's mining and coal mining districts, were dug to dig 20 km of tunnels. They worked alongside the Royal Engineer tunneling companies, now made up of French coal miners and tunnels who had built the London Underground. Many of them were "Bantams", middle-height soldiers who had been rejected by regular units because they did not meet the height requirements; others were initially rejected as too old, but their specialized mining experience made them essential for the tunneling operation. The work was difficult and dangerous. In the Sunnah units of New Zealand, 41 explorers were dead and another 151 were injured during countermechanical operations against Germans whose tunnels attempted to disturb allied tunneling operations. The Arras tunnels connected the holes to form a network running from the center of the city, underneath nobody, to a number of points right in front of the German front lines. The tunnel system could accommodate 20,000 men and was equipped with running water, electric lights, kitchens, latrines, a light guide system and a fully equipped hospital. The tunnels have named the single hollows after their hometown Auckland, Wellington, Nelson, Blenheim, Christchurch and Dunedin for the New Zealanders, Glasgow, Edinburgh, Crewe and London for the British. (For a map of the Arras underground system. Thousands of soldiers were fattened in the galleries for eight days before the start of the Arras offensive on April 9, 1917. At 5:30 am, the outputs were streamlined to allow the Germans were taken in surprise and were pushed back 11 kilometers, which was an extraordinary success for the standards of the time. However, the offensive collapsed and was eventually recalled after that the victims have reached 4,000 per day.The tunnels are accessible via a lifting shaft that takes visitors around 22 meters under the ground inside the tunnel tunnels.The tour consists of guided tours and audioguides on a planned route accessible to wheelchairs Visitors discover the development of the Arras Battle Strategy as well as the daily lives of New Zealand Tunnelers and soldiers of British shipping forces sent to these tunnels to prepare this battle. The site is also a memorial dedicated to the Battle of Arras, with a memorial wall that remembers all the regiments involved in the Battle of Arras. Every year a ceremony is held at 6.30 am on 9 April.
