The Tunnel/s from Nostel Priory to Featherstone myth

Bumped in to an old Featherstone guy at the end of Post Office road looking at the signs on the fence. Got in to conversation about the air raid shelter. Then he came out with a corker I had not heard before.  He asked did I know about the Liptons tunnel? Obviously not. Apparently when this guy was about 8 the Liptons supermarket that is now One Stop was boarded up after closing. He and other kids used to play in the empty building. One day they ventured in to the cellar and found a door leading to a passage. The passage was a tunnel and the kids did not dare go too far. The kids left and returned with candles and one posh kid got a torch. They set off down the tunnel scared to death and eventually came to the end and another opening. The kids found themselves in the cellar of the house that was recently knocked down next to the Cora Pub. The tunnel became a dare thing with the kids who would hide in the tunnel to frighten people trying the dare. I long tunnel by any standards.
One thought is the well that was found a few years ago that is in line with this.
