Quartz, which appears in white or milky tones, recurs across Irish holy sites and prehistoric monuments in ways that suggest a long-held association with spiritual significance, though the reasons remain a matter of debate among archaeologists. At this well in Doonpeter, the pebbles lie about in collections near the water's edge, casual-seeming but almost certainly deliberate, left by visitors over many years.

The well itself sits on the northern side of a graveyard and is a modest, precisely built thing: stone-lined, roughly 90 centimetres long, 65 centimetres wide, and just over a metre deep, approached by two stone steps and set down into the ground. A white metal cross and a statue of Mary in a wooden shelter overlook it from the south. Writing in 1914, a researcher named O'Donoghue recorded that the well was visited on St. John's Eve, the night of 23 June, and that the healing properties of its waters were, in his words, far-famed. That midsummer date places it within a cluster of Irish holy wells that observe the feast of St. John the Baptist, a calendar point that likely absorbed older summer solstice traditions. The well is noted as still in use, meaning the pattern of visiting has not entirely lapsed, even if it now draws fewer people than O'Donoghue's description implies.
