This is not unusual in the Irish countryside, where modern agricultural boundaries have a habit of bisecting ancient earthworks without ceremony, but the effect here is particularly legible: you can trace exactly where the later boundary interrupted the older design.

Ringforts, sometimes called raths, are among the most common ancient monument types in Ireland, typically dating from the early medieval period, roughly 500 to 1000 AD, and thought to have served as enclosed farmsteads for individual families or small communities. The earthen bank at Tooraree Lower originally formed a circle measuring 20.8 metres north to south, though the eastern portion has been lost to the field boundary, leaving the surviving east-west measurement at 15.7 metres. The enclosing bank still stands to an internal height of around half a metre and an external height of 0.65 metres, with an external fosse, that is a ditch dug to reinforce the bank, surviving from the south-east around to the north-east. The fosse measures 0.65 metres deep and 1.6 metres wide. The site was compiled by Denis Power and uploaded to record in August 2011.

The ringfort sits at the foot of an east-facing slope and is currently used as pasture, which means cattle have found their own way in through gaps in the bank on the south-south-west and western sides. The interior is marshy and thick with rushes, sloping gently downward toward the south, so anyone visiting in wetter months should come prepared for soft ground underfoot. The surviving bank and fosse are most clearly visible along the south-east to north-east arc, and that stretch rewards a slow walk around the perimeter, where the relationship between the original earthwork and the later field boundary becomes easy to read.
