What makes it worth pausing over is its relationship with the holy well immediately to its north. Tobereleesh well was once the focus of ritual rounds, the traditional practice of walking a prescribed circuit around sacred sites while praying, and those rounds encompassed both the well and this enclosure together, binding the two into a single devotional geography.

The enclosure itself is roughly oval, measuring around 22 metres north to south and 25 metres east to west internally. The bank is low and wide rather than sharply defined, rising on average about 0.4 metres above the interior, though on the external face it reaches between 0.4 and 1.4 metres depending on where you measure. It is better preserved along the southern arc. Circular enclosures of this kind in Ireland are often early medieval in date, though this one carries no firm dating evidence from the available sources. What distinguishes it is less its physical drama than its documented liturgical role: being incorporated into the rounds of a holy well suggests it held some recognised significance in local devotional practice, perhaps as a cashel or ecclesiastical enclosure, a type of roughly circular walled or embanked boundary that in early Christian Ireland often defined a sacred or monastic precinct.
