These have just been reported in an article in the h@rrogateadvertiser . While playing cricket on the stray a couple of years ago we came across a hatch marked with 'spa water' which was all bolted down. Turns out this was the entrance to underground caverns which were to store the towns mineral waters. The owners- dutchy of lancaster have now decided they are a h+s risk and are to fill them in. Looks like work is currently underway - the earthworks can be seen from the skipton road by the empress pub- just with fencing around. I don't think these will be available too much longer. Built by the Victorians in 1901.
