It carries the designation "structure", a classification broad enough to cover almost anything built by human hands, from a field wall to a souterrain, the latter being an underground stone-lined passage often associated with early medieval settlement. Whatever stands or once stood at Eochaill, it was considered significant enough to be formally noted, and that gap between official recognition and public knowledge gives the site an odd, suspended quality.

Eochaill itself is a Gaelic place name, and names of this type frequently preserve traces of early medieval landownership or territorial identity, though without further detail it would be unwise to read too much into the name alone. County Galway has an exceptionally dense archaeological landscape, with monuments ranging from prehistoric burial cairns to early Christian enclosures to post-medieval estate features, and a loosely typed entry like this one could belong to almost any period or function. The formal record exists; its contents simply have not yet made their way into the public domain.
