“Hohlgangsanlage” are a number of tunnels that were constructed around Jersey during the occupation by slave workers from all over Europe. Hohlgangsanlage (shortened to H0) translates to “cave passage installations” which the Germans intended to use as storage spaces to protect troops and their equipment. Although they are all quite large, every tunnel, excluding HO5, remains uncompleted. Jersey law states that landowners own everything beneath their land until the centre of the Earth, meaning that all the tunnels are privately owned.
“The true story of life in Jersey during the German occupation. The hardship, the heartache and the heroism, in the words of the people who were there. “
H08, which is The Jersey War Tunnels, is the only tunnels that is open to the public without needing permission from the landowner. It was opened in 1946 and operates as a museum.
