Über den Ort

Subterranean fortifications carved into the hillside reveal the brutal scale of wartime occupation across the Channel Islands.

German occupying authorities initiated the tunnel complex following direct fortification commands from Berlin during the Second World War. Labour detachments organized under the Todt organization carved deep galleries into the rock under severe deprivation. Captive labourers from eastern Europe endured extreme physical exhaustion, inadequate nutrition, and rampant illness while excavating the hillside chambers.

Anticipating an invasion by Allied forces, planners converted the subterranean network into a protected casualty station equipped with operating facilities, gas-proof safety doors, and mechanical ventilation. The installation saw no combat before the garrison surrendered following the general European armistice. Postwar abandonment left the corridors cleared of salvageable gear before conversion into a public museum.
