Most people who know about raths, the circular earthwork enclosures built predominantly during the early medieval period in Ireland, roughly between the fifth and twelfth centuries, picture a single bank and ditch. The one at Craggard, on a west-north-west-facing slope in County Limerick, has two concentric earth-and-stone banks with a fosse between them, a fosse being simply a ditch, here measuring just under a metre wide. That second circuit of defence suggests this was a settlement of some consequence, or at least one whose occupants felt the added effort of construction was worthwhile.

The site was recorded and compiled by Denis Power, with aerial photographs taken in March 2006 as part of the Archaeological Survey of Ireland record. The circular enclosed area measures approximately twenty metres in diameter. The inner bank is the better preserved of the two, standing to an external height of around 1.7 metres along its southern arc, which gives a reasonable impression of how substantial the original structure once was. The outer bank is lower and in noticeably poorer condition, scattered with loose stone and cut into at the south by a later field boundary that was laid out without much regard for what was already there. The fosse between the two banks is almost entirely obscured by vegetation, which makes the relationship between the two banks difficult to read from ground level.

The interior slopes gently downward to the east and is largely inaccessible due to dense overgrowth, meaning any exploration is effectively limited to the verges. This is not a site with a visitor car park or an interpretive panel; it sits in working pasture, and the approach and any inspection of the banks should be done with the usual consideration for agricultural land and landowner access. The southern arc of the inner bank is the clearest section to examine, offering the most coherent sense of the original form. The outer bank, despite being the more degraded of the two, repays a close look simply because the loose stone scattered across it raises questions about construction technique and later disturbance that the aerial record alone cannot fully answer.
