What makes it immediately curious is its absence from the Ordnance Survey maps of both 1837 and 1883, meaning that for the better part of two centuries of systematic cartographic record, this earthwork simply did not appear. That omission is not unusual for smaller or less prominent sites, but it does suggest that by the nineteenth century the monument was already so worn down, or so thoroughly absorbed into the agricultural landscape, that surveyors either missed it or judged it unworthy of notation.

A rath is an early medieval enclosed settlement, typically circular, defined by one or more earthen banks with accompanying ditches. At Screeboge, the defining feature is a scarp, a steep earthen face rising to around 1.3 metres, accompanied by an external fosse, or ditch, cut into the ground beside it. That fosse is notably substantial in places, reaching 4.6 metres in width and 0.6 metres in depth along its arc from the south-east round to the west-south-west. On the south-south-west to west-south-west stretch it widens considerably further, to around 7 metres across, which implies either deliberate reinforcement of that particular approach or differential survival depending on how the land was later used. Much of the remainder of the monument has been levelled, a consequence of modern field boundary construction cutting across the site. The original entrance has not been identified, leaving that most telling detail of daily early medieval life, the threshold between the enclosed domestic space and the world outside, unresolved.
