Man-made underground passage in Corwillick

Located 10m within the wall footings of Corwillick cashel (SL015-086001-) on the W side of the interior. A slightly curving portion of the passage (L 5m; Wth 1.35m; D 1.1m) extends in a N-S direction. The walls are lined with drystone random rubble walling and the original rounded end wall survives at the S end. The N end is blocked with earth and access to the remainder of the Man-made underground passage is impossible. Access to the passage is between gaps in the lintels which consist of long rectangular slabs of limestone (Av. L 1.5m; Wth 0.5m; T 0.2m) laid across the passage. At the S end, the passage is covered by a large roughly rectangular slab (L 1.8m; Wth 1.5m; T 0.25m). Compiled by: Patrick F. O'Donovan Date of upload: 21 April 2011
