This holy well is associated with the nearby keeill (PRN 0059). It held an enduring local reputation for the treatment of rheumatism, sufferers of which would leave rags on nearby briars. The site of the spring is not marked on historical or modern maps, and is now lost amongst dense undergrowth.


The Manx Archaeological Survey (1968) recorded that the spring was adjacent to a high hedge-bank, approximately 160 yards north east of the keeill, which would tend to suggest the grid reference given here. The Survey noted that the spring had formerly been accessible and that a stone-lined sump had been created to facilitate the collection of water, but that these features could no longer be found in the undergrowth.


The Survey suggests that the name is derived from the Manx 'Laa'l Boaldyn' (the May festival, Beltane), at which time, despite its pagan associations, the ruined keeill site was also visited.
