Stockport had 3 air raid shelters chiselled out of the soft, red sandstone beneath its foundations during the Second World War - Chestergate, Brinksway and Dodge Hill.
Chestergate is now a museum where, for a fee, you can walk around the largest of the three.
The more adventurous might have a stab at the sealed up, abandoned Dodge Hill.
The place is still lined with the bunk beds that Stockport's citizens once slept on while waiting for German bombers to piss off home.
We also found a bottle of methadone and some empty wraps of smack. Time to leave!
