But the earthwork at Maddyboy is a rath, the Irish term for a ringfort, a type of enclosed farmstead that was the standard unit of rural settlement in early medieval Ireland, typically dating from roughly the fifth to the twelfth centuries. Thousands survive across the country in varying states of preservation, though many have been diminished by later agricultural activity, and this one is no exception.

The two principal Ordnance Survey maps tell a story of gradual encroachment. The 1840 six-inch map records the monument as a roughly circular area with an external diameter of approximately 30 metres, enclosed by a bank, with a post-1700 field boundary already pressing in from the west and a trackway running 50 metres to the south toward the public road. By the time the 25-inch map was produced in 1897, surveyors recorded a raised oval platform with internal dimensions of approximately 35 metres on the northeast-to-southwest axis and 25 metres on the northwest-to-southeast axis, along with evidence of an outer ditch, surviving to about 40 metres in length, along the southern side. A well was also noted on that later map, sitting 10 metres to the northwest. The site lies 120 metres east of a stream that marks the townland boundary with Cloonkeen, placing it in a marginal, wet landscape that may once have offered practical advantages in terms of drainage management or defensibility.

The monument today sits in the western side of an irregularly shaped field, roughly 250 metres west of a public road, with a conifer plantation immediately to its west and modern farm buildings approximately 50 metres to the north. A Google Earth image from June 2018, compiled as part of a survey by Fiona Rooney and Martin Fitzpatrick, shows the tree cover now masking much of the platform's outline. The field boundary transecting the western portion makes it harder to read the full circuit of the original enclosure on the ground. Visitors should expect wet underfoot conditions given the rushy grassland, and the trees, while they obscure the form, do at least mark the location clearly from a short distance.
