pyestock | your guess is as good as mine

The situation on the other side of the corridor was entirely different and incredible in the usual Pyestock way. Three huge compressors sat in three bays with an elevated control room positioned above them. We quickly forgot about the offices, and moved around this incredible industrial space. Some signs suggested that it was called "Cathedral"; a fitting moniker. After taking pictures of the huge Metrovick compressors (not GEC like the Air House) we settled in the control room for a breather. Again, I recognised it from many other photographs and reports, but was unable to put it in any sort of context. Until now.

I regretted not bringing any food at this point and the water was running low. The camera battery was also showing signs of fatigue; this would be a first! Id never exhausted the camera battery before.
