That is considerable. At that scale, a person walking its perimeter would cover a distance closer to a country stroll than a quick circuit of a garden feature. What makes it quietly puzzling is that nobody is entirely certain what it was built to do, and the two leading explanations point in quite different directions.

The enclosure has been tentatively linked to a rath, a type of circular or oval earthen enclosure used in early medieval Ireland as a defended farmstead or settlement, usually for a single family or small community. The connection matters because burials have been recorded in association with the site. Yet there is also a possibility that the structure functioned originally as a barrow, a burial mound of the kind associated with prehistoric funerary practice in Ireland and across north-western Europe, and that it was later adapted and reshaped as a deliberate landscape feature. That second reading would mean the earthwork has been living a double life for centuries, its original purpose obscured by whatever remodelling was carried out to give it a more formal or decorative character in a later era.

The site sits on level ground within an otherwise undulating landscape, which may itself be part of why it was chosen, whether for burial, settlement, or ornamental redesign. Beyond that, the record leaves more questions than answers, which is sometimes the most honest thing archaeology can offer.
