The exact location of the well on St.Boniface Down had been lost and forgotten.
It was re-discovered in 2010 and a plaque has now been installed on a stone monument nearby.
The well has a long history and many legends surround it. Its association with St.Boniface dates from the year 710, when the saint is reputed to have preached from Pulpit Rock in Bonchurch.
Young people would gather at the well on the Saint’s Day to garland it with flowers.
