Man-made underground passage in Letterkeen

Man-made underground passage

What is recorded here

Letterkeen holds a nine-metre earth-cut chamber where postholes still mark the vanished timber roof. Ó Ríordáin and Mac Dermott uncovered the passage in 1950, revealing a stone-flag path that led toward a neighbouring circular house. The narrow depth and deliberate step suggest people walked beneath the rath rather than merely storing things there.
Located in the interior of a rath (MA046-004007-). The Man-made underground passage was excavated (E000015) in 1950 by Ó' Ríordáin and Mac Dermott (1950-1, 100-102). It consisted of an earth-cut chamber (L 9.3m; Wth 1.9m at top, 1.2m at base; D 1m) accessed by an earth-cut step at one end. A series of postholes were interpreted as holding supports for a timber roof. A path of stone flags led from the Man-made underground passage into the interior of a circular house (MA046-004009-).
