What makes it quietly odd is its condition: when it was last formally recorded, the spring was dry. A holy well without water is something of a contradiction, given that the entire tradition of such sites centres on the curative or sacred properties of the water itself.

What remains is still legible as a constructed feature. There are traces of a stone revetment, the facing or lining built to contain and protect the spring, and a channel running westward from the well down to the shore of the island. That channel suggests the site was once managed with some deliberateness, the water directed rather than simply left to pool. Inchagoill, whose name derives from the Irish for Island of the Devout Foreigner, has a notable concentration of early Christian remains, and the well fits into that pattern, associated as it is with the nearby church complex rather than standing in isolation.
