The focal point is a holy well known as Tobernafiaghanta, and at its north-western edge sits a square cairn, roughly 1.35 metres on each side and up to 1.2 metres high, capped in concrete, with the remains of a concrete cross now resting against it rather than standing above it. Cairns of this kind are penitential stations, fixed points in a pattern of prayer and movement known as a "round", in which a pilgrim would walk a prescribed circuit, pausing at each station to pray, often on bare knees. What is striking at Termon is the sheer number of these stations and their arrangement across the landscape. Some thirty metres to the south-west, four cairns are aligned on a north-west to south-east axis. A further three cairns cluster roughly ninety metres south-west of the well. And approximately four hundred metres to the north-east, a separate alignment of four cairns runs on an east-north-east to west-south-west bearing, with a fifth cairn sitting roughly ninety metres to their south. Taken together, the complex amounts to at least twelve individual stations across a considerable spread of ground, suggesting a pilgrimage tradition of some scale and organisation, even if the precise devotional sequence is no longer clear.

The place-name Termon itself is telling. Derived from the Latin "terminus", it was used in early medieval Ireland to denote sanctuary land attached to a church or monastery, territory that enjoyed special legal protection. That background, combined with the well and the density of penitential infrastructure, points to Termon as a site where religious practice was deeply embedded in the land itself, layer upon layer, for centuries.
