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.

Jargon Help

Resistance Nest (RN) = Widerstandsnest (WN)

Strongpoint (STP) = Stützpunkt St.P
Next level up from an RN and consisted of several RN's. STP areas would have a combination of weapons and different branches of the military used. Examples of this can be found with Strongpoint Greve de Lecq and Strongpoint Corbiere
