Extending to a depth of 40ft. on two floors, this impressive bunker was the Command Post (‘Leitstand’) for the naval coastal artillery battery ‘Lothringen’ located here.

One of four built to a similar design in the Channel Islands, the bunker was surmounted by a range-finder and two periscopes to determine the direction and speed of sea targets. Sealed up for safety reasons shortly after the war, the bunker escaped the scrap-drive of the early 1950s, with the result that it is the only example of its type in the Islands to retain the impressive 7 inch-thick armoured cupolas. The bunker has been restored to a very high standard and provides a unique insight into the sheer scale and thoroughness of German military engineering.
