The result is a horseshoe-shaped basin, roughly four metres north to south and just over three metres east to west, with a depth of around 1.6 metres. It is used today by farm animals, which gives some sense of how far its sacred associations have faded from view.

The well is almost certainly the site recorded as Tubber Caogh, identified as a holy well by the local historian James Grove White in his multi-volume work on County Cork published between 1905 and 1925. The Irish word tobar means a well or spring, and such sites were once focal points for devotional practice across Ireland, often associated with a patron saint and visited on a particular feast day for purposes of prayer or ritual. Whether Tubber Caogh retained any organised pattern of veneration into modern times is not recorded, but its inclusion in Grove White's work suggests it was recognised, at least within living memory of his research, as something more than an ordinary field spring. The tree whose roots now shape the well's form adds an quietly arresting quality to the whole thing; what began as incidental growth has become, over time, the very fabric of the structure.
