Known in Irish as Lios na bhFeidhlimí, or Lisnatelimy, this is a bivallate rath, meaning it was enclosed by two concentric banks rather than the single ring more commonly seen across the Irish countryside. That doubled defensive circuit, combined with the scale of what survives, sets it apart from the generality of early medieval enclosed settlements.

The site's layout rewards attention to its detail. The outer bank, with its accompanying fosse (a ditch dug to heighten the defensive effect of the bank above it), survives well only along the northern arc, where it still stands 1.6 metres high on the outside and drops two metres to the bottom of a fosse 3.5 metres across. Moving to the southern half, that outer earthwork fades to a shallow depression, while the inner bank, flat-topped and about six metres wide at its base, continues to hold its full height. A causeway roughly three metres wide cuts through the banks and fosse at the north, forming the original entrance; its eastern edge is marked by a low accompanying bank, and a cluster of less easily explained banks and mounds lie just outside. A more recent gap has been made through the southern bank, presumably for agricultural access. Inside the oval interior, towards the centre, are the sod-covered remains of two circular hut structures, possibly joined to one another. The northern hut measures about 3.4 by 1.8 metres internally, with wall footings still traceable; only a short curved stretch of walling survives from its southern neighbour. Structures of this kind within raths are associated with early medieval settlement, roughly spanning the period from the fifth to the twelfth century, when enclosed farmsteads of this type were the dominant form of rural habitation across Ireland.
