The monitoring post is located on the north side of an un-named minor road, 50 yards west of the Doyle Monument on Jerbourg Road, alongside a cellphone mast. It utilises a former personnel shelter for one of the 22cm guns of the Strassburg Coastal Battery (the open gun pit is still extant nearby). The bunker is overgrown and semi-sunken and is accessed down a flight of steps on the north side.

The bunker has three rooms, an entrance lobby which opens into the 15' X 16' monitoring room (originally the German crew room). At the back of the monitoring room is a small kitchen (a second, smaller crew room). There was originally an escape shaft from the main room but this has now been blocked.

The monitoring room has a central table and chairs for the crew. There is a long table along one wall with shelves above it. There are telephones, a radio and the automatic monitoring instrument. This is a Mini Instruments 7-40, measuring temperature, wind speed, wind direction and radiation levels from sensors and detectors mounted on the roof. This data is then relayed to CD HQ at La Corbinerie. There is a large map cabinet on one side of the room and various maps around the walls. There is a single folding bed and a desk. In one corner of the bunker is the Erickson cellphone equipment.

The kitchen has two microwave ovens and a food preparation surface. The bunker is connected to the mains electricity supply.

Those taking part in the visit were Nick Catford, Keith Ward and Robin Cherry
