Cloonraw Well, in the townland of Glenaclara in County Galway, is one of many such sites scattered across Connacht, recognised as a monument of archaeological significance yet presently yielding very little in the way of documented detail. A holy well, in the Irish tradition, is typically a natural spring or water source associated with a patron saint or pre-Christian veneration, often visited on a particular feast day as part of a pattern, a localised ritual of prayer and circumambulation that could involve walking a set route around the well a prescribed number of times.

Glenaclara itself sits in a quietly rural part of County Galway, and wells in this region frequently carry layers of meaning that long predate Christianity, their sanctity absorbed and reframed over centuries rather than invented wholesale. The name Cloonraw, from the Irish, likely contains the element "cluain", meaning a meadow or pasture, suggesting the well sits within or near low-lying grassland, the kind of terrain where springs surface naturally. Beyond that, the specific history of this well, its patron, any associated traditions, the date of its pattern if one survives, and whether any stonework, enclosure, or votive offerings mark the site, remains undocumented in publicly available sources at present.
