The earthwork has been levelled, probably by centuries of agricultural activity, but the ground still betrays it: a raised oval patch of around 28 metres north to south and 24 metres east to west, its outline traced by a band of denser vegetation roughly three and a half metres wide. Grass and soil remember what ploughs and time have tried to erase.

A ringfort, sometimes called a rath, is one of the most common monument types in the Irish landscape: a roughly circular enclosure, typically defined by one or more earthen banks and ditches, used as a farmstead during the early medieval period. This particular example at Kilgar was recorded as an oval enclosure on the Ordnance Survey six-inch map of 1837, confirming that it was still a visible feature into the nineteenth century. What makes the site additionally interesting is what lies within it. Cropmarks, tonal variations in growing crops or grass that reveal buried features beneath the surface, show a pair of conjoined hut sites at the centre of the levelled monument. These internal structures point to the domestic character of the enclosure and hint at the daily life once organised within its banks. A second ringfort sits roughly 200 metres to the north-west, suggesting this part of Westmeath was once a settled, functioning agricultural landscape rather than isolated farmsteads scattered at random.

The site sits on a natural rise with open views in every direction, a positioning that would have been as practical as it was deliberate for early medieval farmers keeping watch over their land and livestock.
