Channel Island Occupation Society: Bunker Open Days

Discover some of the best preserved WW2 Fortifications in Europe!

The Channel Island Occupation Society (CIOS) Jersey is a voluntary registered charity that has been preserving, restoring and opening German fortifications for around 50 years and has under its wing an impressive range of the standard types of fortifications (Regelbau) constructed locally with most constructed to strict ‘Fortress Standards’ with 2 meter thick concrete reinforced walls and roofs. Many of these structures are restored to near operation condition as well as presenting details of the original crew who manned them and the forced labour used in the construction. A visit to one of our open days will present you with a working atmosphere feel with the chance to get hands on with equipment used at the time as well as events with living history groups presenting relevant displays.

How or when can I visit?

We open the three largest sites in our care regularly, with details below, which are Battery Lothringen (Noirmont Point), Strongpoint Corbiere and Battery Moltke (Les Landes Common), along with other openings that be pre-advertised on CIOS social media platforms.

Visit any of our sites on a guided tour with the experts at Jersey War Tours or join us on one of our open days!
