Last night I went on a guided tour under the Great Northern warehouse. I’m not totally convinced that the risk assessments needed for such an event were in order given the lack of any lighting, numerous trip hazards and a flooded section which wasn’t cordened off. However, it is something that not many people will ever see.
The photo’s are a little grainy which is down to the fact I didn’t know how to use the extended exposure setting and I didn’t have a torch. Subterranea Britannica has similar photos which are a little clearer and has a good history on the canal tunnels. It was a fascinating place to go – i’d recommend it.
