What looks at first like a natural undulation is in fact an early medieval ringfort, a rath, the kind of enclosed farmstead that once dotted the Irish countryside in its thousands. What makes this one quietly interesting is the detail that survives at its centre: the trace of a circular hut, its stone foundations still legible in the turf.

The ringfort itself is modest in scale, roughly 26 metres north to south and 29 metres east to west, enclosed by a low earthen and stone bank that rises only about 20 centimetres above the surrounding ground. Ringforts, known in Irish as raths when defined primarily by earthwork banks, were the typical settlement form of early medieval Ireland, broadly from the fifth to the twelfth centuries, serving as enclosed farmsteads for extended family groups. Inside this one, centred within the interior, sits the remains of a circular hut site measuring approximately 7.8 by 8.3 metres, its perimeter marked by low stone foundations about 20 centimetres high and 1.2 metres wide. These foundations are the kind of feature that weathers quickly when disturbed, and the fact that both the enclosing bank and the internal structure remain legible, however subdued, suggests the site has been left largely undisturbed. The wider landscape around Ballinrobe, near Lough Mask and Lough Carra in County Mayo, was surveyed archaeologically in the early 1990s, and this site was recorded as part of that work.
