Hello, My husband and I were on your tour at 3.15pm on Thursday 16th March, great tour by the way! While we were down in the tunnel our guide Agnes said that she felt it was darker than usual and I have to say there was just something I couldn’t quite put my finger on but it made me feel uncomfortable 😳 Anyway, my husband used the safe in the second room to get a steady picture so I know the attached isn’t him shaking! Agnes said that usually you catch orbs on camera but the attached shows what we caught on a steady surface long exposure photo! It would seem we hadn’t been alone down there after alll! Not sure what it is though!
