Man-made underground passage in Ballymihil

Inside the N perimeter wall of a cashel (CL005-160012-) located in elevated pasture on a natural outcrop with commanding views from SSE to NW. Within an extensive multiperiod field system (CL005-160001-). A Man-made underground passage set within an oval enclosed area abutting the interior N perimeter of the cashel. The entrance to the Man-made underground passage is visible as an exposed stone lintel with a narrow rubble-filled opening beneath (Wth 0.2m; H 0.5m) that extends N for at least 1.5m.    Compiled by: Mary Tunney and Eve Campbell   Date of upload: 7 October 2025
