Man-made underground passage in Rabaun

Located in a cashel (MA072-089----), adjacent to the enclosing wall at SW. A pit or depression (diam. c. 3m; D c. 1m) is evident on the line of the enclosing wall of the cashel. A stone lintel is visible in the NE side of the pit, set 0.5m below interior ground level of the cashel. It covers a subterranean passage (Wth 0.55m; H 0.4m) of drystone construction. The passage is partly infilled with field clearance debris. Compiled by: Jane O’Shaughnessy Date of upload: 21 May 2021
