Tobar na gClog, meaning the well of the bells, is a natural spring in County Dublin that sits quietly in a hollow beside a tree, reached by a short flight of steps. Holy wells, which are freshwater springs associated with early Christian saints and often used for devotional rituals, were once among the most visited sites in the Irish countryside. This one, though, has slipped out of that living tradition entirely. It is no longer venerated.

The well is dedicated to St. John, a dedication recorded by Daly in 1957. Its Irish name, Tobar na gClog, also appears as Tobermaclugg, an anglicisation that softens and slightly obscures the original meaning. The folklorist Caoimhín Ó Danachair documented the site in 1958, noting its position in the hollow and the steps that provide access, and he also photographed it. Those photographs are now held by the National Folklore Collection at UCD and can be viewed through the Dúchas archive online, where they offer a rare visual record of how the well appeared in the mid-twentieth century.

The well is set into the landscape rather than built up above it, so approaching via the steps brings you down to the water rather than up to a structure. The tree beside the hollow is worth noting; trees associated with holy wells in Ireland frequently accumulated offerings of cloth or coins over the centuries, though whether that practice continued here into living memory is not recorded in the available sources. The site is modest and unguarded, the kind of place that rewards a careful look rather than a sweeping one.
