Hohlgangsanlage 1

Hohlgangsanlage are a number of tunnels constructed in Jersey by occupying German forces during the Occupation of Jersey. The Germans intended these bunkers to protect troops and equipment from aerial bombing and to act as fortifications in their own right.

The word Hohlgangsanlage can be translated as "cave passage installations". The Channel Island tunnels are the only ones on the Atlantic wall to be referred to as Hohlganganlagen.

All the tunnels except for Ho5 are incomplete, and some never progressed beyond planning. The partly complete tunnels are, nonetheless, substantial in size. Completed sections were used for various purposes such as storage.

In 1944, when construction stopped, 244,000 m3 of rock had been extracted collectively from Guernsey, Jersey and Alderney (the majority from Jersey). At the same point in 1944 the entire Atlantic Wall from Norway to the Franco-Spanish border, excluding the Channel Islands, had extracted some 225,000 m3.
