Parts of the Coleshill site was excavated by The Ridgeway
Military and Aviation Research Group.
These images were taken when the "observation post" in
Cuckoo Pen Wood was being excavated.
It was the normal double-skinned chamber, except that the inner walls were not
corrugated iron, but asbestos.
We eventually found that the chamber had an access from the top
of a shaft leading to one of the old water tunnels. A pot-holer friend
surveyed the tunnel and found that it led to a point below the site of the former kitchens.
Following a fire in the original ammo store during the war, we think this was
the replacement, carefully sited some distance from the house and
accessible only by discrete means.

The concrete cover over the OB main entrance. this is the view
of the underside, showing the impression of the wooden cover. that in
turn would have been hidden beneath a camouflage.
It's not clear whether this concrete was a later addition made after the facility was
closed, to hide/make
the entrance safe. The small arms rounds were found inside the OB.

The break-out in the Ha ha wall. What looks like the end of a
lintel is only visible because we cheated.
The original was so well disguised that we could only find it by examining the other
side of the wall.
