Another ringfort lies only 220 metres to the northeast, a proximity that hints at a community of neighbouring farmsteads rather than a lone defended homestead on an otherwise empty plain.

The rath itself is a subcircular earthwork measuring roughly 36 metres north to south and 34 metres east to west, defined by an earthen bank and an outer fosse, the fosse being the ditch dug to provide material for the bank and to add an extra defensive or symbolic boundary. Ringforts of this kind were the dominant form of rural settlement in early medieval Ireland, typically dating from around the fifth to the twelfth century, and served as enclosed farmsteads for a family and their livestock. At Flaskagh More, the fosse has largely disappeared into the ground over the centuries, surviving only on the south-western side. A gap on the south-eastern arc may represent the original entrance. Later activity left its mark too: a rectangular structure, now ruined, was built directly onto the line of the northern bank, making use of the old earthwork as a ready-made foundation or boundary. A cluster of gravel pits on the northern side complicates the ground further, though whether these predate or postdate the later building is unclear. The site was noted by Neary as early as 1914, suggesting it was already a recognisable feature in the local landscape well before modern archaeological recording began.
