There is little to announce it: a scattering of loose stone to the east, the soft give of damp ground underfoot. Yet this modest well carries a dedication, and with it a history that links the landscape to an early Christian figure largely forgotten outside the local parish.

The well is known as Toberloona, the name deriving from the Irish tobar, meaning well, and Lugna, the saint to whom it is dedicated. Saint Lugna is not among the better-known figures of the Irish saints' calendar, but dedications of this kind often mark the sites of very early Christian activity, sometimes pre-dating the formal church buildings that later grew up nearby. Holy wells across Ireland were typically places of pattern, a local gathering held on a saint's feast day that combined prayer with communal ritual, and many remained in use for centuries. Whether Toberloona ever served such a function in a sustained way is not recorded, but the proximity of the well to the church beside it suggests the two sites were understood as connected, the sacred landscape shaped by both.

The well sits immediately west of the church and is unenclosed, with no formal structure protecting the spring itself. Visitors exploring the area around Ballywalter would find it in the rough ground that borders the churchyard, though its low-key appearance means it rewards those who know to look rather than those passing at a distance.
