The relationship between ancient enclosure and modern agriculture here is not one of preservation but of gradual absorption, and that overlap is precisely what makes the site worth knowing about.

Drumlins, the low elongated hills left behind by retreating glaciers, are characteristic of the Monaghan landscape, and their summits were frequently chosen as sites for ring-forts, the enclosed farmsteads of early medieval Ireland typically defined by one or more earthen banks and ditches. At Ramoy, the enclosure was recorded in 1968 as a roughly circular area about thirty metres in diameter, bounded by an earthen bank some five metres wide. The bank varied in surviving height from around 0.7 metres on the southern side to about 1.5 metres on the northern, suggesting differential erosion or disturbance over the centuries. Outside the bank ran a fosse, the ditch element of the defensive arrangement, measuring between 3.35 and four metres across at the top and up to 1.2 metres deep. A berm, the flat strip of ground between the inner bank and the outer ditch, had been removed or obliterated along the north-east to south-south-east arc, precisely where farm buildings and a yard had established themselves. There is also an entrance gap about three metres wide on the eastern side, though whether this corresponds to an original opening or represents a later breach is uncertain. By 1995, the interior of the enclosure had been taken over entirely by farm structures, completing a process of incremental reuse that would not have seemed unusual to many generations of rural builders working with whatever level ground a hilltop offered.
