What makes this place quietly arresting is the entrance: a gap less than a metre wide in the north wall, flanked on either side by small square recesses cut into the stonework, both of which were found to contain coins. The gesture is ancient and instinctive, the kind of votive deposit left at holy wells across Ireland for centuries, the well understood as a threshold between the ordinary and something else.

The wellhouse itself is modest in its dimensions, roughly two and a half metres east to west and about two metres north to south, with mortared stone walls surviving to a maximum height of half a metre. A stone channel, thirty centimetres wide, carried the water northward from the well before it rejoined the stream. The structure was open to the sky when recorded, though a 1954 file note suggests it may originally have been roofed. A cross stood approximately five metres to the west, accompanied by a recumbent cross-slab and an architectural fragment, pointing to a more substantial religious presence at some earlier point. Holy wells in Ireland were often focal points for patterns, the local devotional gatherings that combined prayer with communal ritual, and the arrangement of well, cross, and slab here suggests this place once held a meaningful role in the devotional landscape of the parish. The name Tobermacduagh connects the site to Mac Duach, the early medieval saint associated with Kilmacduagh monastery nearby, lending the well a more specific identity within the region's ecclesiastical geography. Faint traces of a hollow to the south of the well may mark the course of an older channel of the stream, a reminder that even the small waterways around such sites have shifted over time.
