Two large stone lintels, the roofing slabs of what was once a souterrain, have worked their way free of the ground, one displaced, one breaking through the turf nearby, as if the structure beneath is gradually giving itself away.

A souterrain is a man-made underground passage or chamber, typically stone-lined and roofed with large flat slabs, built during the early medieval period and usually associated with a nearby settlement or enclosure such as a rath, the circular earthen ringforts that dot the Irish countryside. This example sits inside the bank of one such rath, just west of a farm road running roughly north-north-east to south-south-west. When Gannon described it in 1972, it was still recognisable as a passage running east to west, entered from the west end, with a turn northward at its eastern end. By the time later observers came to look, the structure had collapsed into a roughly circular depression about two metres across and half a metre deep, the passage itself no longer accessible, its form only legible through those displaced roofing stones lying at the surface.
