The personal name attached to it is a small puzzle in itself; such informal designations often preserve a memory of ownership or association stretching back centuries, though in this case no further detail about the Martin in question has survived in the record.

A rath, in simple terms, is a roughly circular enclosure defined by an earthen bank and ditch, typically used in early medieval Ireland as a farmstead or defended homestead. This particular example was originally subcircular in plan, measuring around 33 metres on its north-south axis. A later field wall slices through the monument at both north and south, and whatever earthworks once existed to the west have been lost entirely. What does survive tells a layered story of slow attrition: from the north round to the east, the enclosure is still legible as a scarp, and from there round to the south a low bank persists, though even that is partly buried beneath a field boundary. A faint band of different vegetation at the south-east may be the last faint echo of an external fosse, the shallow ditch that would originally have run around the outside of the bank. There is also a gap at the east-south-east that could represent the original entrance to the enclosure, though centuries of agricultural activity make certainty difficult.

The monument sits in open grassland and its earthworks, much reduced as they are, remain visible as subtle changes in ground level and texture rather than dramatic upstanding features. The contrast between the surviving eastern arc and the near-total erasure to the west gives a clear sense of how thoroughly ordinary farming practice, the laying of walls and the working of fields across generations, can quietly dismantle even a structure that once organised the lives of people on this hill.
