Measuring roughly fifteen metres in diameter, it is either a small enclosure in its own right or an annexe appended to a larger enclosure to its northwest. That ambiguity is itself telling. Enclosures of this kind, typically formed by a raised earthen bank or a stone wall defining a roughly circular space, are among the most common yet least understood monument types in the Irish countryside. They could mark a farmstead, a place of burial, a ritual space, or simply a practical enclosure for livestock; without excavation, the ground rarely gives up a straight answer.

The relationship between this smaller feature and its larger neighbour to the northwest is the detail that makes Tigroney worth a second look. Annexes attached to main enclosures appear across Ireland and may have served as stock pens, as separated working areas, or as later additions to an original settlement. The Tigroney example was first recorded during a field inspection carried out in 1990, meaning it had gone formally unnoticed until relatively recently. Whether it was always considered part of the same complex as the larger enclosure, or was simply a separate, smaller monument that happened to sit nearby, remains an open question.
