Man-made underground passage in Tawnymucklagh

In the W half of a cashel (SL046-032001-). A low partially sod-covered stony rise (Wth c. 2m; L 6.2m) extends E into the interior from the cashel wall at W. The S side of the rise is built up to compensate for the slope of the interior of the cashel. Four in situ lintels are partially exposed on the surface and gaps between them reveal a drystone-built passage (Wth 0.65m at E, 0.9m at W; H 0.4m), largely infilled with loose stones and blocked at the W end. The above description is derived from the published 'Archaeological Inventory of County Sligo' compiled by Ursula Egan, Elizabeth Byrne, Mary Sleeman with Sheila Ronan and Connie Murphy (Dublin Stationery Office, 2005).
