It is a rath, the most common type of early medieval enclosure in Ireland, built as a fortified farmstead, typically by a single family or household of some standing. Thousands survive across the country, yet each one carries its own accumulated strangeness, a domestic life compressed into a bank of earth that has outlasted the people, the animals, and the buildings it once contained.

The Davidstown rath was already recorded on the first edition Ordnance Survey six-inch map of 1837, shown there as a roughly circular earthwork. By the time the revised twenty-five-inch map was produced in 1913, its shape had shifted slightly in the cartographic record to something more oval, and it had begun to absorb a field boundary running northeast to southwest to northwest, the kind of quiet annexation that happens when agricultural land quietly closes around an older monument. When surveyors examined it in 1980, they found an enclosure roughly twenty-two metres in diameter, bounded by a bank with a notably sharp profile and a relatively flat top. Fragments of internal stone facing survived on the northwest to southwest and southeast to south sections of the bank. A gap in the northern to north-northeast section of the bank, with stone facing visible on its eastern side, is a likely candidate for the original entrance. In places the bank has been reduced to a scarp, a sloped face rather than a full raised bank, and dry stone revetment has been used to shore up these sections. A modern field fence now runs along part of the perimeter from west to north, tying the ancient boundary into the contemporary one. A second ringfort lies approximately 110 metres to the southeast, suggesting that this part of Westmeath once held a cluster of early medieval settlement activity, farmsteads close enough to suggest community, or at least neighbourliness, across the centuries.
