There is a rural road heading east and then south from Whitewell which ends at a T intersection at these Google Maps coordinates 53.903428,-2.500162 . If you head east the road quickly curves to the south again. At the bend of the road on the east side is an odd underground structure with an arched door. It can be seen on Google Street View on the east side of the bend. Is this just a cold storage location or is there some historic significance to it? We will be traveling this route in June on a jaunt that will take us from north to south through the Pennines and the Forest of Bowland.
