I filmed this visit in 2001. Secret Second World War Tunnels, on the Isle of Portland. Underground Naval Operational Centre & vast fuel storage tunnels. Tragic deaths after the Foylebank air raid, East Weares & Verne Citadel. Portland Naval base, East Weares & Verne Citadel. The tunnels are no longer accessible as they are in full use by Portland Bunkers Ltd. **NB There's a new version without the atmospheric ambient music which 2 people thought was intrusive**
