What is recorded here

Man-made underground passage in Doonflin Upper is a man-made underground passage in Doonflin Upper, County Sligo, Ireland. A narrow depression 10.5 metres long, 1.2 metres wide and 0.3 metres deep extends from a two-metre gap in the southern bank into the rath, curving slightly towards the north-northwest. Random stones protrude through the sod cover in parts of this shallow trench. The visible remains may represent a collapsed underground passage rather than an open digging.
