A ringfort is a roughly circular enclosed settlement, typically of early medieval date, defined by an earthen bank and ditch. Here in the townland of Glebe, the bank is long gone, levelled at some point before 1972 when it was already being described as a monument that had been destroyed. What remains is a subtly raised platform of ground, roughly 44 metres across, where a darker band of vegetation quietly traces the outline of what was once there.

The 1837 Ordnance Survey Fair Plan map recorded the site as a large oval enclosure, annotated simply as "fort", which suggests the earthworks were still visible and recognised at that time. Sometime in the intervening century and a half, the banks were flattened, most likely through agricultural improvement. Drainage works have left their own marks on the landscape; crop marks surrounding the site may relate to post-1700 drainage activity, and a drain running east to west cuts across the southern perimeter. Faint cultivation ridges are still discernible running north-northeast to south-southwest through the interior of the levelled monument. A second, smaller circular area, approximately 15 metres in diameter, defined by the same dark vegetation signature, adjoins the main site to the northeast. A possible second ringfort lies around 155 metres to the northwest, near a stream that forms the townland boundary with Cullenagh, suggesting this corner of Westmeath once held a modest concentration of early settlement.

The site is most legible from the air. An aerial photograph taken in November 2011 showed the outline of the levelled monument with considerable clarity, the variation in vegetation picking out the buried features in a way that ground-level observation simply cannot match. On foot, in wet grassland, the slightly raised platform and the tonal differences in the grass are the only clues that anything is there at all.
