Holy wells have a long tradition in the Highlands, with speculation that they may date back into pre-Christian times (Map 3.2; Morris and Morris 1982). As with the Iron Age, there appears to have been a focus on underground, watery areas, with High Pasture Cave in Skye as the main example (Case study High Pasture Cave). However, there has been little detailed dating of holy wells, and further investigation of their early origins would be useful.
