WN Fort Aubin

St. Aubin's Fort is a small walled fortification 500 metres off shore in St. Aubin's Bay. The first fort was built in 1542. In the beginning it served to protect the harbour from pirates, and in later years was developed as part of the island defences during the many Franco English wars. Major alterations were made in the 19th C. and during the WWII Occupation of Jersey, 1940-45, the Germans added concrete bunkers and
gun emplacements.

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.
