Enclosure of uncertain period
SMR NO: ARM 017:011
GRIDREF: H98653984
CONDITION: NO VISIBLE REMAINS
"A rather irregular oval earthwork C.50m N-S and 38m E-W is shown on the 1863 OS 6" map. It was site[d] on a small eminence above a stream which marks the townland boundary. A steep natural scarp surmounted by a modern hedge bank is all that survives, probably reflecting the W side of the monument."Rath of the Early Christian Period.
SMR NO: ARM 017:035
GRIDREF: H99223966
CONDITION: SOME REMAINS
"A circular "Fort" is shown on the 1835 OS 6" map, but only "Site of Fort" is indicated on the 1863 edition. The site is bisected by a hedge bank & to the N of this a low platform 41.5m EW can still be recognised. It is defined on the W & N by the arc of a gently scarp failing c.0.6m to the ground level. On the E the line of the perimeter is preserved in a curving held boundary and there is a much steeper scarp faliing 1.5m. The nearby deserted settlement probably accounts for the destruction of the S side."
