The land has been drained and improved so thoroughly that nothing survives above ground, yet the site remains on the archaeological record as a real, catalogued thing, a rectangular feature roughly 33 by 37 metres in extent, its edges once defined by stone.

The enclosure was recorded by McCaffrey in 1952, who noted its dimensions and offered a tentative classification as a stone fort, the question mark in his original description suggesting he was working with limited or ambiguous evidence even then. Stone forts, or cashels, are drystone-walled enclosures associated broadly with the early medieval period in Ireland, used variously as farmsteads, settlement boundaries, or places of local defence. What makes the Keamsellagh example quietly interesting is its context: McCaffrey noted that it sat between a second enclosure to the east and a settlement cluster to the west, suggesting this was not an isolated feature but part of a denser pattern of activity in the landscape. That cluster of sites has since been swallowed by agricultural improvement, and the present pasture gives no indication that any of it was ever there.
