A ringfort, the type of circular earthwork enclosure built in early medieval Ireland as a farmstead and defended homestead, once occupied a slight rise in the pastureland here. By the early 1960s it had already been reduced to a ring of bushes and what may have been a low bank. Then it was bulldozed entirely, and the ground was smoothed back into ordinary farmland.

Ordnance Survey six-inch maps, the detailed nineteenth-century series that recorded so much of Ireland's landscape before the age of heavy machinery, had noted the site as a roughly circular enclosure about thirty metres in diameter. That record, alongside local memory of the demolition, is effectively all that survives on the ground. Or rather, all that survives above it. Aerial photography taken in 2011 and visible on Google Earth as recently as 2019 shows the outline of the fort still faintly legible from the air, where slight differences in soil moisture and grass growth trace the ghost of the old circular boundary. This kind of crop or soil mark is often the only way vanished earthworks of this type remain detectable at all.

There is nothing to see at Rakerin if you visit in person. The site sits in working pasture, and no earthwork, ditch, or bank remains to break the surface. The interest here is really in the gap itself, in what the aerial outline suggests about how many such monuments disappeared during the mid-twentieth century when land improvement schemes and agricultural machinery made short work of features that had survived for well over a thousand years.
