The townland of Kilmachugh is in the parish of Kilclooney in Armagh County. It is labelled number 19 on the map.
The Environment and Heritage Service Sites and Monuments Record (2002) notes the following in this townland:
"Blair's Cave", an enclosure of uncertain, possibly Early Christian, period.
SMR NO: ARM 017:039
CONDITION: NO VISIBLE REMAINS
"The 1863 OS 6" map shows a large oval earthwork c.165m NE-SW x 145m NW-SE. The S perimeter was once preserved by a field boundary, but this area is now occupied by bungalows & gardens. The remaining circumference has also been lost & there are no visible remains. The site is bisected by a steep-sided stream valley which forms the townland boundary [between Lisnagat and Kilmachugh]. Paterson refers to "Blair's Cave" on a bank of the river. The entrance was blocked but it is possible that it was a souterrain (the souterrain is in Lisnagat townland - see Arm 017:049). The bridge to N is called Blairs Bridge.

"A low, roughly circular platform 35m N-W x 33.5m E-W has survived. The W perimeter has been levelled, and only a faint scarp is visible, while the N, E & W sides have been preserved by incorporation into a curving hedge boundary. Here the scarp is well defined and,on the S, falls c.1 m to the base of a recut ditch 1.5m wide & 0.4m deep. The interior of the site has been heavily cultivated."
