In the middle of a field to the south side of the outer peri-track.
The bunker is in poor condition due to flooding and the build up of silt. The main entrance way is totally back filled with rubble. The emergency hatch is missing but the ladder is still in place, the shaft has been back filled with farm rubbish but is still accessible.Inside a few features remain such as the wooden frames in the issue hatches and some light switches.Inside the bunker there is either a differant room layout or an extra room added, unable to verify this at the time due to site conditions. Further rescearch has shown this to be a 11012⁄41 type Battle HQ, see RAF Barrow.
