• MA063-018 Ringfort - unclassified
  Description

  In pasture, located at the break of slope at top of a gentle N-facing slope, with a stream c. 10m to S, which feeds into another stream 200m to NE. Good views generally, particularly extensive to NW. Cultivation ridges on a roughly N–S axis area are visible in the surrounding field. Slightly raised circular area (29.4m E–W; c. 27m N–S) defined by a low sod-covered stone bank (Wth c. 3m; int. H 0.4m at N, 0.2m at S; ext. H 0.85m at N, 0.35m at S). The bank is best defined NW–E, where its external scarp is enhanced by the natural fall of ground. Elsewhere, it is rather low and dilapidated; large stones protruding in parts, especially to E–SE, which may be remnants of external facing. The enclosing bank appears stony and may represent the modified remains of an earthen bank or the remains of a cashel wall. There is no clearly defined entrance gap. A subrectangular quarry pit (6.5m NE–SW; 5.7m NW–SE; D 1m) is dug into the In the E half of the interior. It is bordered on the SW side by a sod-covered stony heap of upcast. Several other sod-covered stony heaps (diam. c. 5m; H c. 0.6m) are dotted around the interior. A property wall on an N–S axis cuts across the E edge of the interior. A rath (MA063-019----) located is c. 270m to SE. Compiled by: Jane O'Shaughnessy Date of upload: 9 July 2020

• MA063-019 Ringfort - rath
  Description

  In pasture, located on a rise. Views are good generally, extensive to NW–N over expanses of bog and pasture. The fields to S and SW are under forestry. Slightly raised, roughly oval area (35.5m NNE-SSW; c. 31m E–W) defined by a sod-covered stony scarp (Wth slope 2.8m at NE, c. 2m at SW; H 0.75m at NE, 0.4m at SW). The scarp is best defined to N–NE where it is enhanced by the natural slope. In parts on the S arc it retains a stony internal rim. The interior has a slight slope down to S. The surface feels uneven underfoot. The NW−W part of the interior is covered by an impenetrable thicket of blackthorn and brambles. There is also blackthorn on the perimeter at E, but much of the E half on the interior is grassy and free of overgrowth. A ringfort (MA063-018) is located c. 270m to NW.

• MA063-040 Enclosure
  Description

  In undulating pasture, located on top of a low hill with extensive views. A circular deeply sunken area (int. 24.5m N–S; 25m E–W) defined by a drystone wall facing (Wth 1.8m) on the vertical sides (int. depth 1.6m at N, 1.8m at S) of the sunken interior. The walling rises proud of exterior ground level to a height of 0.4-0.6m at NW–E, but elsewhere around the perimeter the external face of the wall is somewhat dilapidated or tumbled, with heaps of field clearance stone accumulated against it in parts. There is a break (Wth 0.8m) in the wall at N. The W half of the sunken interior is level, but the E half slopes down slightly to the E. According to local information, this enclosure was used as sheep pen. Compiled by: Jane O’Shaughnessy Date of upload: 2 October 2020

• MA063-049 Water mill - horizontal-wheeled
  Description

  In wet pasture, located on a small N-flowing stream, just below the point where a number of smaller streams joined the main stream. The Mullaghanol River is c. 60m to W. This horizontal water mill has uncovered at a depth of c. 1m below ground surface during reclamation/drainage operations undertaken by a mechanical digger in 1982. The discovered was reported to the National Museum. One timber remained in situ at the stream, probably part of the wall of the mill-house. Fourteen timbers were displaced during the works. The majority of the timbers were in a damaged and fragmentary condition, but six were almost intact and these were removed to the National Museum for preservation. Two of these six timbers are large solid timber beams (L 2.8-3m; Wth 0.4-0.42m; T 0.19-0.23m), one with a tenon (L 0.22m; Wth 0.1m); these are likely to have formed part of the wall or roof of the mill-house. Three thinner planks (L 1.8-2m; Wth 0.36-0.57m; T 0.06-0.12m) may have been floor planks; one plank has a tenon projecting from the underside, and another plank has a tenon at both ends and a fragment of a connecting timber projecting outwards at an angle. The sixth timber (L 1.8m; Wth 0.4m; T 0.07m) is part of the head-race: it is hollowed-out, giving it raised sides, and narrows towards one end; the narrow end has a tenon, which would have allowed it to be connected either to another section of the head-race or to the flume. Two millstones were also found. The larger one (diam. 63m; T 0.06m) has one smooth surface and a central perforation (diam. 0.1m), and is likely to have been the upper stone of a grinding pair. The second millstone (diam. 0.3m; T 0.07m) is smaller, with an irregular outline, a small central perforation, a rough upper surface with a rounded profile, and a worn surface on the underside.

• MA063-055 Fulacht fia
  Description

  In pasture, located on a strip of level ground bordered to E by the Mullaghanoe River and to W by rising ground. Listed as fulacht fia in the SMR (1991) and RMP (1997) based on local information. No evidence of a fulacht fia was evident at ground level when the location was inspected in 1996. Land reclamation has taken place here and much spoil was spread over the ground surface. It is possible that the fulacht fia has been levelled. Compiled by: Jane O’Shaughnessy Date of upload: 2 October 2020

• MA063-057 Enclosure
  Description

  In pasture, incorporating a rise in sharply undulating terrain. There are extensive views to N over lowlying bog and pasture, and rising ground to S. Not shown on the 1838 and 1920 OS 6-inch maps. Listed in the SMR (1991) and RMP (1997) as an enclosure on the basis of a semicircular feature, curving SSE−N, visible in an aerial photograph (GSI G 133-4; Roll 231, pr. 16) (SMR file). At ground level there is a roughly circular rise (c. 34m N−S; 34.5m E−W) defined NE−SSE by a pronounced scarp or slope and at S−NW by a scarp/slope incorporated into a curving drystone wall. The outline is poorly defined at NNW−NNE. The wall (int. H 0.8m; ext. H 1.4m at S) on the SW arc is similar in general form to local field walls. It appears to have been c. 1m in original width. The external wall face is relatively intact but internal face has collapsed to a broad slump of loose stones, and is topped by heaps of loose field clearance stones, giving it a total width, including slump, of c. 3m. This broad slump of stones appears to have been pushed up here following levelling of nearby field walls. The remains may outline the W half of an originally circular enclosure, but this is very uncertain. Compiled by: Jane O’Shaughnessy Date of upload: 2 October 2020

• MA063-066 Burnt mound
  Description

  In reclaimed pasture, located at the base of a gentle rise on the NW side of a natural depression (c. 30m across), which prior to reclamation was wet and marshy. According to local information, this monument consisted of a small, low roughly semi-circular grass-covered mound. It was levelled during land reclamation, which exposed a concentration (diam. c. 10m) of angular stone fragments in greasy, black soil. There appeared to be stones defining a shallow hollow area in front of the mound. When inspected in 1996, the location was grass-covered and there was no surface evidence of the mound, but probing beneath the soil surface confirmed the presence of burnt stone and dark soil. A farm track lies immediately to NW. Compiled by: Jane O’Shaughnessy Date of upload: 9 December 2020

• MA063-067 Burnt mound
  Description

  In wettish drained rough pasture, at the base of rising ground to W. A low, overgrowth-covered mound (diam. c. 7m; H 0.7m) of angular stone fragments in dark brown/black, peaty soil. It is difficult to determine its full dimensions. A large stone is visible on the S edge of the mound. There is a field fence immediately to W. According to the landowner, immediately to S of this mound there was a circular area (diam. c. 10m) defined by a rough low line or kerb of stones. This area was disturbed during land reclamation. When inspected, this area was evident as uneven ground, disturbed by clearance activity/burning of tree stumps, and covered in brambles. A few isolated concentrations of stones were visible but formed no coherent pattern. Compiled by: Jane O’Shaughnessy Date of upload: 9 December 2020

• MA063-068 Fulacht fia
  Description

  In pasture on bank of a tributary stream of the Mullaghanoe River. D-shaped mound (9m N–S; 3m E–W; H 0.6m) composed of shattered sandstone fragments in a matrix of black, charcoal-rich soil. The stream borders the straight E side of the mound, with a gap of c. 0.4m between the mound and the stream bank. When inspected in 1996, small loose fragments of dried-out/weathered timber were lying adjacent to the E side of the mound. The mound is densely covered by brambles.

• MA063-070 Burnt mound
  Description

  In a flat stretch of damp pasture bordered to E by the N-flowing Mullaghanoe River, and to W by rising ground. A grass-covered kidney-shaped, mound (10.5m N–S; c. 9m E–W; H 0.6m) composed of heat-shattered stone in charcoal-rich soil, with a shallow indentation or hollow on the E side. It appears to be located on the course of a tributary stream, which is now dried up. At the time of inspection in 1996, reclamation works had recently taken place in the field. A NNW−SSE field bank located immediately to W of the fulacht fia had been levelled and the spoil was spread over the field. A surface spread (10.5m N−S; c. 7m E−E) of burnt stone in black soil was visible 4m to E of the fulacht fia. The source of this material was unclear –it may have been a levelled part of the upstanding fulacht fia or possibly part of a separate feature. Compiled by: Jane O’Shaughnessy Date of upload: 9 December 2020

• MA063-071 Fulacht fia
  Description

  In pasture, at a gentle bend of a stream, overlooked by a hillock to SW, and by gently rising ground to W and NW. This fulacht fia consists of a semi-circular mound (12m N–S; 9m E–W; H 0.5m above ground level at W, H c. 1m above stream bed at E) located on the W bank of the stream, with the central hollow of the mound facing the stream. The mound is largely sod-covered, but the E side has been eroded by the stream, exposing shattered sandstone fragments in a matrix of black, charcoal-rich soil. Roughly mid-way along the section face, trough timbers are visible at a depth of 0.9m below the top of the mound, protruding more or less at the level of the base of the stream channel. The timbers, which span a width of 1.5m and project only c. 0.005-0.012m from the section face, represent four contiguously laid horizontal planks lining the base of a trough. In the section face, the portion of the mound directly above the timbers is composed of peaty soil with a noticeably lower concentration of burnt stone, flanked to N and S by dense concentrations of burnt stone. A fragment of a hazelnut shell was visible in the mound material. Some burnt stone is also evident in section on the E bank of the stream.
