Inside the Netherton canal tunnel there are seven air shafts, which guided the tunnel builders when they were building the tunnel and then provided air and a little bit of light for the canal users as they passed through.

This is what the airshaft looks like from the top; I would have taken pictures of the tunnel end of these shafts, but it was a bit too dark and my camera's flash wasn't strong enough.

See previous pictures for information about Netherton canal tunnel. It's not something you see every day!
