Bradley woods cold store

After a long discussion with a friend, we have decided that this 'building' was a cold store for the adjacent house (long since demolished). We did think about a shelter of some description, but the construction was too old and not strong enough to be for any period of the 20th centuary.
At the rear of the building, it looks like a door and a window, but behind them is some seriously old rock so possibly some form of shelving?
Unfortunately someone has decided to use it as a rubbish dump!

The pics were taken on my iPhone, hence the dark/smokey interior pic & not really sure it deserves a re-visit, but hey.
