Man-made underground passage in Carrowkeribly

In a rath (MA039-108----). According to local information, a depression (3m N-S; 8m E-W), located in the W half of the rath interior indicates the position of a Man-made underground passage. The grass-covered depression, which partly intrudes into the inner face of the bank, extends from the inner edge of the bank across the rath interior to E for 8m. It has a depth of 0.75m below ground level at its W end, close to the bank, but becomes shallower towards its E end. The sides of the depression appear to be earthen, with no clear evidence of stone facing. Compiled by: Jane O’Shaughnessy Date of upload: 1 April 2020
