The Wart Well - Almescliffe Crags (North Rigton)
(SE 2680 4900)
Almescliffe Crags is a large and conspicuous rocky outcrop located to the south-west of Harrogate. On top of the crags are several large weather worn basins which collect water, with one of these basins being known as the Wart Well.
Edmund Bogg (1) records a folk magic cure for warts, which took place at the Wart well. This involved pricking the offending warts with a pin and letting the blood drip into the water in the basin, after which the hands were washed in the water. 
In local folklore the crags were also home to the faerie folk, who were suspected of taking newborn babies from nearby farms and leaving changelings in their place. It is interesting to note the use of pins in the wart cure at the well, as at other sites pins were left as offerings to the fairy folk.

Simon's Cross/Wart well

By way of a comparison, the picture on the right shows another Wart Well, this time from Simonstone in Lancashire. In the past a natural boulder has been used for a cross base and later the water that collected in the empty socket hole became known as a cure for warts. (Thanks to Phil Reeder for this information).
