The Carrière Wellington museum consists of a visitor centre displaying historic artifacts and presenting the historical context of the Battle of Arras, including the work of the tunnellers and the military strategy that underlay the tunnels' construction. It was opened to the public on 1 March 2008.

The tunnels are accessed via a lift shaft that takes visitors approximately 22 m (70 ft) under the ground inside the galleries of the underground quarry. The tour consists of both guided and audio guided tours on a planned path accessible for wheelchairs. The visitors discover the development of the strategy of the Battle of Arras, and also the daily life of the tunnelers of New-Zealand and the soldiers of the British Expeditionary Forces sent in these tunnels to prepare this battle.
