This is rather a unique kind of tunnel, 1290yards long & small in diameter -less than 5ft tall x 3ft wide & parts you have to sliver through snake-like. Driven through limestone, it also has a number of airshafts (I counted 4).
It's quite well ventilated considering the above & that both ends are almost buried, but all the shafts are open & a fresh breeze was flowing through.
Very little details of it are about on the net, but from what i gather, it was built in the Victorian era by the mining conglomerates to channel drinking water to Conisbrough .

Here's a map of the area. Those bushes dotted along the line are the airshafts, the south-west end is about 15 yards from Conisbrough Viaduct:
Inside: the darkness awaits...
Bit further on & the arched roof gives way to a flat roof, mixture of bare rock & metal plating:
Shotgun Shootout:
1st eastern shaft, this shot was a bit difficult, as there was a rainstorm pouring through, inevitable wet lens:
One of the slivery through bits:
In the middle, bricks give way to bare rock, the pipe runs all the way through this tunnel, makes for a bit easier walking going along it:
Another airshaft, there was a couple of young toads down here, of all places!:
I had an Epic Camera Fail halfway through, the mud accumulated from slivering through parts of the narrowed tunnel had got into it & terminated the power-up mechanism, but the rest of the tunnel is on teh video.
Looks like a new camera is needed, good job i was thinking of upgrading anyhow!
