The Jersey War Tunnels also known as Hohlgangsanlage 8, or the German Underground Hospital, was a partially completed underground hospital, built during the German occupation, which was built by forced and slave workers. There is over 1 Km of Tunnels, and now these tunnels are preserved, and is a memorial to the slave workers who lost their lives building this.
Ho8 was intended to be a vast network of underground tunnels that would allow the German occupying infantry to withstand Allied air raids and bombardment (in preparation for an invasion).
The tunnels were then opened in 1946 by the states of jersey, however in 1961 it was ruled that the tunnels was owned by the land above it, therefore fell to private ownership. the complex was restored and made into a museum with collections of occupation memorabilia.
