Not because it is particularly remote or obscured by vegetation, but because it no longer has a surface at all. At some point before the site was recorded, farm machinery passed over the ground and the roof gave way, briefly exposing an earth-cut chamber below before the whole thing was filled back in. The land closed over it again, and that was that.

Souterrains are underground stone- or earth-lined passages and chambers, typically associated with early medieval settlement in Ireland, and thought to have served as places of refuge, food storage, or both. They are common enough across Munster, though most survive at least partially intact, their entrances concealed beneath field walls or the floors of ruined structures. The one at Kilgobnet is unusual precisely because its brief moment of visibility came not through excavation or deliberate investigation, but through accident, and the response was simply to return the ground to its former appearance. There is now no visible surface trace whatsoever.
