• MA062-123001 Enclosure
  Description

  In average pasture. Shown on the 1837 OS 6-inch map as a subrectangular area outlined by a dashed line, annotated as ‘Graveyard’; depicted on the 1919 edition as a hachured subrecatangular area, annotated as ‘Children’s burial ground’. A slightly raised rectangular area (38.8m NNE–SSW; 37.6m WNW–ESE) defined on the NE side by a low stone bank (Wth 2-3m; int. H 0.3m; ext. H 0.45m) and on the SW and NW sides by a sod-covered stony scarp (Wth slope c. 2m; ext. H 0.9m, at NW). The SE side is incorporated into a drystone field wall; immediately inside the field wall there is a slight stony rise, possibly a remnant of the original enclosing element. A sod-covered stony rise (5m NW–SE; 2.3m NE–SW) abuts the enclosing scarp at SSW, possibly a field clearance heap. There is a break (Wth 5.8m) in the enclosing scarp at NW at the intersection of the WNW and NNE sides, and a low area (Wth 3.2m) at the E end of the NNE side; it is not clear if either of these represents an original entrance. Approximately three quarters of the interior space is raised above exterior ground level, leaving a relatively narrow strip (Wth 8-10m) of slightly lower ground on the NE and E margins of the interior. The roughly square, elevated area (c. 21m NNE-SSW; c. 20m WNW–ESE) was used as a children’s burial ground (MA062-123002-). According to local information, there is a bullaun stone (MA062-123003-) associated with the enclosure. Grass cover, with hawthorn bushes growing on the perimeter at S-SW and along the field wall at E. Conifers are planted in the field immediately to N.

• MA062-123002 Children's burial ground
  Description

  In a rectangular enclosure (MA062-123001). A roughly square, level elevated area (c. 21m NNE-SSW; c. 20m WNW–ESE) within the interior of the rectangular enclosure (MA062-123001) was used for the burial of unbaptized babies. The majority of the raised area is covered with low, uninscribed stone grave markers. Some stones are set upright in the ground but there is also a scatter of stones that appear to simply rest on the ground. A narrow strip of slightly lower ground (Wth c. 8m) at NE, E and SE remains clear of gravemarkers. The upright stone gravemarkers are close-set and arranged in rough N-S rows; most protrude no more than 0.3m above the sod. There is an uninscribed prostrate slab, now broken in two, close to the S margin of the burial ground; according to local information, this marks the grave of a local man buried here in the 1930’s (SMR file, 1984). According to tradition, funerals approached the burial ground by following the line of the stony bank on the N and NE side of the enclosure.

• MA062-123003 Bullaun stone
  Description

  In an enclosure (MA062-123001-) and children’s burial ground (MA062-123002-). According to local information, a bullaun stone (MA062-123003-) was found here (SMR file: pers. comm. Francis McCann 1991). It was not visible within the enclosure during an inspection in 1997. Compiled by: Jane O’Shaughnessy Date of upload: 26 January 2021

• MA062-124 Megalithic tomb - unclassified
  Description

  In the SE corner of a modern rectilinear pasture field, located on a W-facing slope of a natural rise in an area of gently undulating terrain. This unclassified megalithic tomb consists of a subrectangular cairn (12.6m E–W; 5.4m N–S; H 0.4-0.8m) of small and medium-sized stones, with a few larger stones also visible. A single upright slab (L 1.3m; T 0.4m), with long axis aligned N–S, protrudes from the W end of the cairn, rising 0.3m above the top of the cairn; this may be an in situ orthostat. The cairn is largely sod-covered; the E end is obscured by brambles and hawthorn bushes. Compiled by: Jane O’Shaughnessy Date of upload: 26 January 2021

• MA062-127 House - indeterminate date
  Description

  In pasture, located on a natural rocky rise, with good views of the surrounding countryside. A roughly circular area (4.8m NNE-SSW), defined by an earth and stone bank (Wth 1.5-1.7m; ext. H 1m) (Pers. comm. R. Crumlish, 2009). At S−E the interior and the enclosing bank are engulfed in scrub. There is a rath (MA062-128----) and a house (MA062-128002-) c. 70m to WSW and another rath (MA062-130----) c. 115m to E. Compiled by: Jane O’Shaughnessy Date of upload: 26 January 2021

• MA062-128 Ringfort - rath
  Description

  In rough, stony pasture, scattered with field clearance cairns, located on a low rise with generally good views. There is a higher rise to ESE. Roughly circular raised area (diam. 26.6m WNW–ESE) defined N–E by a scarp (H 1.5m; Wth slope 5.3m at NE), at SE–W by a low stony rise/stone bank (Wth c. 2.5m; int. H 0.3m; ext. H 0.5m) and incorporated W–N into a later field wall. The enclosing scarp is quite substantial, broadly sloping and rather uneven, with field clearance stones piled against it in parts. The interior has an uneven, stone-strewn surface. There is a souterrain (MA062-128001-) in the SW quadrant. A field wall on a WNW–ESE axis bisects the interior roughly centrally. Dense blackthorn and brambles obscures much of the interior. A possible house (MA062-128002-) is located immediately to SE. Compiled by: Jane O’Shaughnessy Date of upload: 26 January 2021

• MA062-128001 Souterrain
  Description

  Located in the SW quadrant of a rath (MA062-128). A collapsed souterrain passage extends from close to the rath perimeter at SW in a shallow arc for c. 10m through the interior to NNE. It is evident as a narrow, grassed-over depression (Wth 1m; D 0.4m) with stones protruding randomly in parts. A single roof lintel remains in situ towards the NNE end. The remains are largely obscured by blackthorn scrub. Compiled by: Jane O’Shaughnessy Date of upload: 26 January 2021

• MA062-128002 House - indeterminate date
  Description

  In rough stony pasture, dotted with field clearance cairns. A rath (MA062-128----) is located 2m to NW. Roughly circular, slightly raised area (8m N-S; 6.5m E-W) defined by a sod-covered stone bank or ‘wall’ (Wth 1.2-1.5m; int. H 0.2m; ext. H 0.3-0.4m). Immediately inside the stone bank at E is an oblong sunken feature (4m N-S; 1m E-W; D 0.35m-0.6m), partly infilled with stones, including one large slab. Obscured by brambles and ferns.

• MA062-129 Megalithic tomb - wedge tomb
  Description

  In rough stony pasture, dotted with field clearance cairns. This record was included in the SMR (1991) and the RMP (1997) as a possible wedge tomb based on information received from a local source (SMR file 1991). Inspected in 1997, no visible trace at ground level. Compiled by: Jane O’Shaughnessy Date of upload: 26 January 2021

• MA062-130 Ringfort - rath
  Description

  In pasture, located on a low rise with good views. Slightly raised, oval area (32.6m N–S; 23m E–W) defined at W–N by a stony scarp (H 1.4m at NW) enhanced by a natural fall of ground, at NNE–ESE by a broad stony rise (Wth 3.7m; int. H 0.2m; ext. H 1.3m), possibly a collapsed wall, and at SE–S by a drystone field wall, which respects the curve of the rath. At S–SW the enclosing element has been levelled. The enclosing scarp is most substantial at NW, where it has been terraced and faced at the base of the slope by a later drystone field wall. There is a break (Wth 1.6m) in the stone bank/scarp at NE and a very low area at E. This rath was greatly modified in the late 18th or early 19th century. A road/farm track (Wth 3m), flanked by drystone field walls, cuts through the centre of the rath on a N–S axis; this road is shown on the 1837 OS 6-inch map. An E−W drystone field wall extends to W through the W half of the rath interior; this is all that remains of a second trackway, also shown on the 1837 map, which branched off the N−S road. In the NW quadrant of the rath interior, there is a grassed-over irregular-shaped depression (4.5m NE–SW; 4m NW–SE; D 0.5m), from which stones protrude; it is of uncertain significance, but appears to be the result of relatively recent disturbance.

• MA062-132 Ringfort - rath
  Description

  In a thicket of overgrowth, located on a low rise in an area of undulating average pasture. There is a fall of ground to S for c. 300m towards a stream valley. Broadly oval area (c. 27m NW–SE; c. 32m NE–SW) defined at E–SW by sod-covered stony scarp (Wth c. 1-1.1m), which has been incorporated into a later field wall on the SW arc; at WSW−NE by a scarp, which retains a slightly raised stony internal rim (Wth 2-3m) and is faced externally with drystone walling. Outside the scarp at WNW–NE there is an outer enclosing drystone wall (Wth 1.2m; int. H 0.15m; ext. H 1.3m). The intervening gap (Wth 3m) between it and the inner scarp/wall appears to be a terrace rather than a sunken fosse, and varies in width from its narrowest point of 1.4m at WNW, where it intersects with a field fence, to a width of 3m at NE. It is uncertain if this outer wall is original to the ringfort or merely a later field wall. The enclosure is bisected slightly NW of centre by a property wall on a ENE–WSW axis. A shallow, oval stony depression (6m NE–SW; 2m NW–SE; D 0.3m) in NW half of the interior is overlain by the property wall. In the SE half of the interior, there is an irregular-shaped hollow (4m E–W; 3m N–S; D 0.5m). The interior is engulfed in overgrowth and the perimeter is densely ringed with blackthorn. There is a possible cashel (MA062-130----) located c. 250m to SW. Compiled by: Jane O’Shaughnessy Date of upload: 26 January 2021
