The enclosure at Garbally, in the barony of Coshma, is one of those sites that asks something of the imagination; on the ground it reads as little more than a curving field boundary, but from above it resolves into the ghost of a roughly circular form, the kind of shape that does not occur by accident in the Irish landscape.

The site sits in wet pasture roughly 600 metres west of the Morningstar River, just northwest of the townland boundary with Brackvoe. It was recorded by Martin Fitzpatrick and uploaded to the national record in March 2021. The enclosure shows up on Ordnance Survey Ireland 25-inch mapping as a curved field boundary running from north to east, and it appears more fully on orthophotography taken between 2005 and 2012, as well as on Google Earth imagery, where the circular cropmark becomes easier to read. Cropmarks of this kind form when buried or levelled features affect how vegetation grows above them, with buried ditches often retaining moisture and producing lusher, greener growth that traces the original outline. Adding further interest to the location is a possible levelled ringfort recorded just 20 metres to the northwest. Ringforts, the most common monument type in Ireland, were typically circular enclosures of earth or stone used as farmsteads during the early medieval period, roughly 500 to 1000 AD, and their clustering in a landscape often signals a zone of sustained early settlement.

Because so little survives above ground, this is not a site that rewards an unguided visit on foot. The wet pasture setting means the ground can be heavy going, particularly outside the summer months. The most useful approach is to study the aerial imagery first, using the OSi Maps viewer or Google Earth to locate the cropmark and orient yourself before setting out. The enclosure lies immediately northwest of the Garbally and Brackvoe townland boundary, which can serve as a rough navigational marker. If you do reach the field in the right conditions, look for the slight arc of the field boundary that curves from the north around toward the east; that curve is the last legible trace of whatever stood here.
