​​Workers at Lager Wick were employed at the local quarry at Les Maltières (now disused), from where stone was taken to a nearby stone crushing plant (now apartments). Sand was gathered from Grouville Bay for many concrete fortifications erected during the Occupation.

​As German Forces wished to build an anti-tank wall to protect Grouville Bay from enemy landings, an enormous reserve sand heap was created on Grouville Common, accessed by a track. Lorries were loaded with a steam grab, which arrived in September 1942 and was based opposite Links Hotel (today Links Court). By 1942 much of the haulage was done by horse-drawn carriage.

​Origins of human bones found on Grouville Common in late August 1943 remain unexplained. On site archaeological fieldwork revealed that as Lager Wick was built on flood-prone marshland, two steps were taken to facilitate construction. First, a layer of sand was placed across the site’s western end to provide firmer foundations for huts. This was carried on a temporary narrow-gauge railway. Secondly, some barracks were built on stilts - concrete foundations were seemingly not used.

​By April 1943, the camp comprised seven barracks and a small hut, possibly a guard house, near the entrance. The huts were arranged on four sides around what was probably a parade ground but disguised as an ornamental garden with a central flower bed - likely intended to prevent identification from the air. Another four barracks extended the camp along the road in an L-shape. The camp’s total size was approximately 200 square metres.

​By October 1943, one of the original seven barracks alongside the main road had been removed and the remainder enclosed by barbed wire. By April 1944, three barrack huts had burnt down and the number of barracks around the original parade ground had decreased to five. According to writings by the late Michael Ginns, Lager Wick was abandoned by D-Day and the remaining timber removed by civilians for use as firewood during the war’s last, harsh, winter.

​By October 1944, all wooden buildings had been removed, leaving a few concrete footings and hut stilts, and what appears to be significant holes around the camp’s perimeter after the removal of barbed wire posts.

​All that remains of the camp today, hidden beneath undergrowth, are the entrance pillars and part of the kitchen block and potato store. Archaeological material discovered on site is now in the Jersey Heritage collection.​
