What gives it away is the grass-covered platform, roughly twenty-one metres across, its perimeter still just about traceable as a stone wall that has subsided over centuries into a low scarp, standing no more than a metre high in places. A later field wall cuts straight through it east to west, and a quarry has bitten into its south-eastern quarter, so the structure has been interrupted and partially consumed by the working landscape around it. The original entrance, if it ever left a clear trace, has not been identified.

This kind of monument is broadly classified as a ringfort, a form of enclosed settlement that was common across Ireland during the early medieval period, roughly from the fifth to the twelfth century. Most were built to define and protect a farmstead, with the enclosing bank or wall serving as much as a social marker as a defensive one. The Drumcashel example is a stone-walled variant rather than the more familiar earthen rath, its boundary constructed from local material that has since collapsed to the low rubble scarp visible today. The Glenade valley setting is worth noting: the valley floor location, rather than a prominent hilltop, places it in a tradition of lowland enclosed sites more concerned with agricultural territory than with commanding views or military advantage.
