The late William Doble, who's family still operates the sand quarry on the site, told me that it was known as Warren Well.
Apparently it was once tradition to gather on the cliff top at Easter and sing hymns, whilst fishing boats would gather on the sea at the foot of the cliff and do the same. It was never explained to me as to why this meeting took place, or for how long the tradition had been observed.
Hope this was of interest.
