A ring barrow, a low circular earthwork used in prehistoric Ireland as a funerary monument, sits in ordinary pasture on a gentle south-westerly slope at Dromtrasna North. What makes it quietly arresting is not its scale but its completeness: a small, level interior enclosed by a fosse, which is a shallow ditch cut into the earth, and a low outer bank, all of it still largely intact despite centuries of agricultural activity around it.

The monument was recorded and compiled by Denis Power, with the record uploaded in August 2011. It measures roughly 7.75 metres north to south and 8.2 metres east to west, making it a modest but clearly defined circular space. The enclosing fosse is about 0.3 metres deep and 0.8 metres wide, with the bank rising to around 0.4 metres on its interior face. What distinguishes this particular example is the presence of two opposing causewayed entrances, one to the east at 1.4 metres wide and one to the west at 1.8 metres wide. Causeways like these are gaps left uncut in the ditch, allowing deliberate access across the threshold of the monument, and their presence on opposite sides here suggests some intentional orientation, though what ritual or practical purpose that served is a matter for inference rather than record.

The interior is level and grass-covered, though it has been noticeably poached by cattle, meaning the ground surface has been disturbed and churned by hooves over time. The site sits in working pasture, so access is likely to require landowner permission. The earthworks are low and would be easy to overlook at certain times of year when the grass is long, but the circuit of the fosse and bank becomes easier to read in lower winter or early spring light, when shadows pick out the subtle changes in ground level. The two entrance causeways are the detail worth locating, since they give the monument a legibility that a simple ring of earth alone would not.
