Ringforts, sometimes called raths, are roughly circular enclosures defined by one or more earthen banks and ditches, built predominantly during the early medieval period as farmsteads or places of habitation. This one at Callow is not especially dramatic to look at, which is precisely what makes it worth paying attention to. The bank that once enclosed it still traces a circle of around fifty metres in diameter, but it has been worn and scraped by generations of grazing animals until sections of it have been reduced to little more than a sloped edge in the earth.

According to survey notes compiled by Denis Power, the bank varies considerably depending on where you measure it. On the interior, what remains stands only about 0.45 metres high, while the external face still reaches roughly 1.8 metres in places, suggesting the original structure had some presence in the landscape even if it was never a fortress in any military sense. Cattle have done the most visible damage, eroding the bank along its north-north-east to east arc and again from the south around to the south-west. There is a gap in the bank at the south-west, about 6.3 metres wide, which may represent the original entrance, though it is impossible to be certain given the degree of erosion. On the eastern side of the interior, an irregular depression has been recorded, most likely the result of later quarrying activity rather than anything associated with the fort's original occupation. The limestone that breaks through the surface at the centre of the interior is a feature of the broader geology of the area rather than a deliberate construction.

Access to the site requires crossing agricultural land, so the usual considerations around landowner permission apply. The enclosing bank and much of the interior are partially obscured by scrub overgrowth, which makes the circuit of the monument easier to trace in winter or early spring before vegetation fills back in. A field boundary now abuts the bank on its northern side, a reminder that farming has continued to reshape this corner of the landscape long after whoever once lived within the enclosure departed. The exposed limestone underfoot and the slight rise towards the centre of the interior are the clearest things to orient yourself by once you are inside.
