Description

Rock Well is a historic structure set into the bank beside a path. It features a short arched tunnel that is half a metre wide, constructed from local coarse gritstone. Water flows from beneath the arch over a stone sill and is now collected in a slate cattle-trough, which has cemented and bolted joints. This trough likely dates from after the well was no longer used for human needs. To the left of the well, there is a large worn stone that was used for beating cloth. The bank on the right side of the well is supported with stone revetment for a short distance.

Local climate

Rock Well sits in a wetter-than-average part of the UK, with an average of 1,130 mm of rain a year. This makes it wetter than 88% of listed buildings in the UK. Its exposure to wind-driven rain is greater than that of 95% of listed buildings.

It experiences an average of 9 freeze-thaw cycles a year, fewer than 92% of listed buildings. Of these, 3 follow at least 1 mm of rain in the preceding 48 hours. Average temperatures at this location have risen by 0.3°C per decade since 1991.
