It is not a ruin in any dramatic sense, just a field boundary, 26 metres running to the north-west, then curving northward for a further 32 metres, 0.7 metres thick and only 0.4 metres above the ground. What makes it worth pausing over is precisely that disappearance: the wall does not end, it sinks, absorbed into deeper bog, leaving the question of what lies beneath entirely open.

The wall sits in rough pasture at Cummeenduvasig, a townland in the rugged interior of south-west Kerry, and it begins just north of what may be a cashel, the circular stone enclosure used in early medieval Ireland as a farmstead or small defended homestead. The possible cashel nearby has not been confirmed, but the spatial relationship between the two features is suggestive. Walls like this one were laid down to divide and manage land, and when they survive at all it is often because the bog grew up around them, preserving stone that would otherwise have been robbed for later building. The bog here has done the work of an archive, though an imperfect one: it shows you enough to know something was here, and conceals the rest.
