Strongpoint Plemont

In 2014 we were asked by The National Trust For Jersey (NT) if we could help them with documenting their work in returning the Plemont site back to nature. Plemont was a large Strongpoint during the Occupation and later became the site of an abandoned and derelict Pontins Holiday Camp. The land was purchased by the trust with the aim to return it back to nature as well as protecting the WWII fortifications that remained. We quickly agreed to help and were given unrestricted access to the site for this purpose as well as the NT allowing us to produce a full research page of the site. We worked closely with the developers, through the trust, as well as others providing details of where we believed some of the lost bunkers to be. It was important to us that we found all of the remaining bunkers to make sure the demolition of the holiday camp did not also take out a bunker. Our work below shows what a great job the National Trust have done and we are also glad to report that from our work we were able to save one of the bunkers from being lost for ever.

WWII History of the site.

After the Germans arrived in July 1940 they quickly set up defensive positions across the Channel Islands. The troopsof the 216th Infantry Division who would have setup field emplacements at Plemont. The area was an important site as the communications cable to Guernsey left Jersey from there. It also was a holiday camp which would have been useful for billeting the soldiers. 319th IR arrive and reinforced field positions are put in place in different levels becoming a Strongpoint.

Site of Interest 1.
M3 Army Observation Bunker

The M3 is a reinforced field type bunker built by the German Army in 1942 to provide a range for the Artillery Batteries. The M3 was one of many positioned around the coast providing range and positioning of targets at sea. When we first visited the site it was hard to tell this bunker was still there. The last three photos show some of the German graffiti which was painted over but is now becoming more clear.

Site of Interest 2 Ringstand

This is a mortar ringstand which the camp converted to a waste furness. Because of this the damage was unrepairable and the structure faced collapse. It was agreed to fill it with cement so that it would remain on the site for many years to come. It most likely housed a 5cm Mortar.

Site of Interest 3 Machine Gun Emplacement and Shelter

The personnel shelter has been constructed using a British Anderson Shelter. The French received many of these from Britain which the Germans captured and brought them to the islands to use for their troops.

Site of Interest 4 Personnel Shelter

No sign was ever found of this shelter circled in red. On a post on Unseen Jersey a member kindly shared this holiday snap from the camp. It looks like the personnel bunker in the red circle and has a very interesting wording of "GESTEINBOHR Kp 77" meaning Rock Drilling Company 77.

Site of Interest 6 Turret Ringstand

This looked to be a ringstand with a tank turret on top. It is buried and we were not able to dig down to see if it is still there. It is most likely to be for the MG311(f) in a APX-R turret.

Site of Interest 7 Ringstand for a 20cm Spigot mortar

This position was identified very clearly on the research but as you can see above there was no trace on our first few months of visits. Then close to the last months of demolition we spotted what looked to be this bunker buried. We alerted both the fortifications officer and the NT site manager and thankfully this position was saved.

Exploring bunkers:

• Always get permission from the owner
• Take a torch, a spare and one more for luck
• Don't go alone & tell someone where you will be and for how long
• You will get dirty as most are often full of rubbish and may have been used as a public toilet
• Anything you find still belongs to the person that owns the property
Unexploded ordnance is still found in Jersey if you see or find anything that looks like ordnance please call the bomb disposal officer on 01534 612 612.

The Channel Island Occupation Society are guardians of 5 sites which have all been restored or have been made to look like they did in the Second World War. Visits to these sites help fund the work they do and we encourage you to take a look at the opening times and visit them. They also have a wide range of books and reviews, all of which are an excellent resource for education.

Whether you are an established Battlefield Guide, retired from the craft, interested in how it is done or considering a future in guiding, the International Guild of Battlefield Guides is for you. Kimberley and Phil are both associate members and recommend you visit their website to show support.
