The well itself sits within a heavily overgrown depression, bounded by a low stone wall measuring roughly four metres north to south and just over three metres east to west. It is the kind of structure that can pass entirely unnoticed, reading from a distance as little more than a slight hollow in the ground, yet it carries a dedication to Ireland's patron saint and belongs to a tradition of holy wells that once formed a dense, living network of local devotion across the country.

Holy wells in Ireland were rarely grand affairs. Their significance lay not in architecture but in association, with particular saints lending their names and, by extension, their protective or curative power to a local water source. Patterns, the traditional gatherings held at such wells on a saint's feast day, were once common social and religious occasions, often involving circumambulation of the site, the tying of cloth offerings to nearby trees, and prayer. The well at Carrownalecka is documented in a 1994 archaeological survey of the Ballinrobe district, compiled by D. Lavelle for the Lough Mask and Lough Carra Tourist Development Association, which placed it among the area's lesser-known but genuine survivals of this practice. Whether any pattern tradition was maintained here into recent centuries, the record does not say.
