An enclosure on such a site would typically mark the boundary of an early ecclesiastical or secular compound, a defined space, often roughly circular, demarcated by an earthen bank or stone wall, within which a community once organised its daily life. That this one remains so sparsely documented only adds to its atmosphere of withdrawal from the historical record.

The specific history of this enclosure, its date, its builders, and its original purpose, has not yet been fully recorded in publicly accessible form. What can be said is that Saints Island sits within a landscape shaped by centuries of early Christian activity along the western seaboard, where small enclosed settlements, whether monastic or domestic, were common features from roughly the sixth century onwards. The name alone points to a tradition of sanctity attached to the place, even if the precise dedication has been lost or was never formally fixed in surviving documents.
