Despite being a physically upstanding monument, it never made it onto the Ordnance Survey's historic maps, which makes it something of a cartographic ghost. That absence alone gives it a particular kind of interest: a structure that has sat above the surrounding landscape for centuries without ever being formally drawn into the official picture.

The fort is a rath, the Irish term for a ringfort, which was the most common type of rural settlement in early medieval Ireland, typically consisting of a circular or oval area enclosed by one or more earthen banks and ditches. This example measures approximately 46 metres east to west and 39 metres north to south, sitting at 312 feet (95 metres) above sea level near a townland boundary with Ballydaheen. Its existence in the documentary record comes not from any map but from the Ordnance Survey Field Name Books, specifically the entry for Bruff Parish (OSNB Bruff Parish, 346), which notes that to the north-east there is "another (fort) in which is a Trigl. Station called Bruffhill." That trigonometrical station, one of the fixed survey points used by the Ordnance Survey to triangulate accurate measurements across the country, was planted within the fort itself, meaning that at some point in the nineteenth century, surveyors were working inside this enclosure without bothering to record the enclosure on their published sheets. The site was compiled by Alison McQueen and Vera Rahilly and uploaded to the record in November 2020.

The earthwork is visible on aerial and satellite imagery, including orthoimages from 2005 through to 2017, which gives a reasonable sense of its current condition in pasture. Anyone approaching should expect farmland rather than a managed heritage site; the hill is modest in height but gives an open aspect. The oval outline is most clearly read from above, so consulting one of the available satellite images beforehand will help a visitor orient themselves on the ground. There is no signage or formal access, and the land is privately held grazing land, so the usual courtesies apply.
