Man-made underground passage in Rathdonnell

In the W half of a rath (MA030-043----). The SW quadrant of the rath interior is at a higher level that the rest of the interior. At the N edge of this area there is a surface depression (Diam. c. 2m; D 0.6m), which may indicated the presence of a Man-made underground passage. There is a shallow dip at the inner edge of the rath bank c. 3m to W. Compiled by: Jane O’Shaughnessy Date of upload: 16 April 2018
