Recorded monuments

• MA111-018 Castle - unclassified
  Description

  In average pasture, at the E edge of a broad expanse of flat, lowlying damp ground, affording good views SW, W and NW. From a point c. 40m to E of the castle, ground rises gradually to form a N−S ridge, which overlooks the castle and restricts views to E. A prominent hillock c. 60m to SE of the castle is effectively a small spur of that ridge. Indicated on the 1838 OS 6-inch map as a rectangular building named ‘Castle (ruin)’ with a rectangular walled enclosure (possibly a bawn) (MA111-018001-) immediately to N; it is shown on the 1930 edition as an oblong or rectangular hachured feature, named ‘Castle (Site of)’ and the rectangular enclosure at N is not shown. The remains consist of a low, subrectangular grass-covered mound (c. 18m E−W; c. 12m N−S), with a fairly well defined scarp (H 0.7m; Wth slope 2.8-3m) on the S and W sides. The N and E sides are poorly defined and partly obscured by scattered heaps of large boulders, with an irregular cairn of loose stones at the E end. Stones and boulders also cover the uneven top of the mound. Some of the stone scatter may be displaced rubble from the castle, but much of it seems to be the result of field clearance. There are no obvious pieces of masonry or cut stone and no in situ traces of walling can be seen in the mound. The E edge of the mound is irregular and ragged suggesting that the mound has been truncated at this end; the current E−W dimension appears shorter than shown on the 6-inch maps. It may have originally extended to E by a further 10-13m or so. Nettles grow densely on the top of the mound, and a broad band of nettles extends E−W at the base of the mound on the N side, perhaps indicating the line of a razed wall. Slight traces of the rectangular enclosure or possible bawn (MA111-018001-), shown on the 1838 6-inch map, can be seen to N of the mound.

• MA111-018001 Bawn
  Description

  Immediately to N of a castle (MA111-018----). On the 1838 OS 6-inch map a rectangular enclosure, possibly a bawn, is indicated immediately to N of a rectangular building named ‘Castle (ruin)’; it is not shown on the 1930 edition. Slight traces of this enclosure/possible bawn can be traced at ground level. It appears to have measured c. 30m E−W by c. 20-25m N−S. The S side is bordered by the castle mound, where an E−W band of nettles may preserve its outline. The W side is defined by a slight stony scarp (H 0.5m; Wth slope 1.7m) which extends N from the W edge of the castle mound to a present-day E−W drystone field wall, which incorporates remnants of the N wall of the possible bawn. The E side is barely discernible, with a hint of a scarp visible in parts. Two portions of the N wall of the possible bawn are visible in section beneath the E−W field wall, one portion equating with the W end of the N wall, and one with the E end. The W portion is visible as a broadly slumped bank (c. 8m E-W; H 0.95m) of jumbled earth and stone, overlain by the later field wall. The core or central part of this bank appears to be composed of the remains of a wall (c. 2-2.8m E-W; 0.95m) with a thin flat horizontal slab ( L 1m E−W; D 0.1m) visible at its base, on top of which are two rough courses of large stones. Loose stone and earth slump outwards from this stony core. The E portion of the wall (L 7.8m E−W; H 0.55m) is similarly visible in section, consisting of 2-3 courses of rough stone blocks, with earth in the interstices. It is topped by a thin sod layer, on which the present-day field wall is built. Compiled by: Jane O'Shaughnessy Date of upload: 16 December 2022

• MA111-019 Earthwork
  Description

  In an expanse of reclaimed pasture. Listed in the SMR (1991) and RMP (1996) as a possible earthwork on the basis of a subcircular feature visible in an aerial photograph (SMR file: GSI M 26 -7; Roll 205, pr. 0). At this location there is a low oval grass-covered rise (c. 28m N–S; c. 15m E–W). It has a relatively level top and gently sloping sides, with a broader, more gradual slope on the W side. At its NNW end there is a partly infilled quarry pit, and this may be the feature visible in the photograph. A farm track skirts the W side of the rise, cutting into the base of the slope. The rise appears to be a natural feature, and there is no convincing evidence at ground level of an archaeological monument. Compiled by: Jane O'Shaughnessy Date of upload: 16 December 2022

• MA111-020 Ringfort - rath
  Description

  In good pasture, straddling a low natural elevation in an area of gently undulating, lowlying terrain. Views are good but not extensive, best to E−SE and are restricted to W−NW by a slight rise and by field fences. Raised circular area (31.8m E−W; 35.5m N−S) defined by a substantial earthen bank (Wth 5.7m at N, 5.1m at S; int. H 0.7-0.8m ay N, 0.5m at S; ext. H 1.6m at N, 1.5m at S), best preserved on the N arc and reduced to a scarp on the S arc. At NE−SE the external slope of the bank is truncated by a later N−S field wall, and a portion of the bank (L 4-5m) on the W arc has been partly dug away. A narrow line of low stones protrudes randomly from the crest of the bank in parts, possibly the remnants of an old field fence. A possible external fosse is evident as a very slight surface depression (Wth 2.5-3m) at S−NW, marked by a growth of thistles; it is truncated at N by a grassed-over area of quarrying. The W half of the interior is level. Slightly E of centre there is a marked break of slope from which ground slopes down towards the enclosing bank, levelling out again within 2m of the bank; the drop in height is c. 0.6m. A low portion of bank at ENE−E may indicate an original entrance, but no clearly defined gap is apparent as the bank here is now obscured by the N−S field wall. The bank is lightly ringed with hawthorn trees and brambles; dense brambles lines the N−S field wall at E. Compiled by: Jane O'Shaughnessy Date of upload: 16 December 2022

• MA111-021 Enclosure
  Description

  In pasture, on a broad level elevation; ground slopes gradually to E. Shown on the 1838 OS 6-inch map as a circular embanked enclosure (diam. c. 15-20m); it is not shown on the 1930 edition, although a shallow curve shown in a N−S field fence probably preserved the W arc of the enclosure. This enclosure has been levelled. A shallow, roughly circular depression (diam. c. 9m) is evident, bordered on the E half by a cropmark (arc of slightly yellow grass), possibly indicating a levelled bank. A straight N−S field wall crosses the W edge of the circular depression; the curving kink in the wall shown on the 1930 OS 6-inch map has been removed and the wall rebuilt so that it is now completely linear.

• MA111-022 Enclosure
  Description

  In pasture, on a slight elevation, with good views of the surrounding gently undulating terrain. There is a farmstead c. 20m to E. A circular embanked enclosure (diam. c. 30-35m) is shown on the 1838 OS 6-inch map; it is not shown on the 1930 edition, although a shallow kink in a field fence probably respects the original NW arc of the enclosure. This possible rath has been levelled, and the location is subsumed into two small rectangular fields bordered by drystone walls. A shallow curve in a N−S field wall preserves the curve of the W−NW arc of the enclosure; the wall appears to have been built on remnants of the original enclosing scarp (H 0.6m; Wth slope 2.4m). A slight undulation c. 30m to E probably represents a remnant of the bank on the NE arc of the enclosure. There is no visible trace of the S half of the enclosure.

• MA111-102 Burnt mound
  Description

  In rough pasture, located on the SE edge of a broad, expanse of flat reclaimed pasture and boggy ground. An E–W property wall intervenes between the mound and a natural rise which lies a few meters to NW. An irregular-shaped mound (c. 11.4m N–S; c. 9.6m E–W; H 0.4-0.5m at N, 0.65m at S) composed of small angular stones in a matrix of black soil. The mound has suffered disturbance in recent years and survives as three close-set, sod-covered rises. At S are two conjoined rises (diam. of each c. 5m) with an intervening shallow dip (Wth 1m). A tractor tract, consisting of an E–W depression (Wth 2m), separates the S portion from a third low rise (diam. 5-6m) at N. There is another burnt mound (MA111-103----) c. 100m to E in the same field, and a burnt mound (MA111-104001-) and a fulacht fia (MA111-104002-) are located c. 80-100m to SE.

• MA111-103 Burnt mound
  Description

  In pasture, located at the base of the SW slope of a hillock, bordering a broad, expanse of flat reclaimed pasture and boggy ground which stretches to SW–W. A very low, sod-covered irregular-shaped rise (max. dim. c. 6m), the limits of which are not clearly defined. On the S side of the mound there is a shallow dip (diam c. 2m) opening to SW but it is unclear if this represents the location of a trough or is the result of recent disturbance. There is a small circular sod-covered rise (diam. 3-4m) c. 2m to W and 2m to SW of the latter, another small circular rise (2.5m N−S; 2.7m E-W), but it is unclear if either of these is associated with the burnt mound. There is another burnt mound (MA111-102----) c. 100m to W in the same field, and a burnt mound (MA111-104001-) and a fulacht fia (MA111-104002-) are located c. 80-100m to SSW.

• MA111-104001 Burnt mound
  Description

  In average pasture, in the NW corner of a field, located at the base of the W-facing slope, bordering an expanse of flat reclaimed pasture and rush-grown, boggy ground which stretches to W–NW. A low mound (c. 6m E–W; c. 14m N–S) consisting of two sod-covered rises separated by a depression (Wth 3m), possibly indicating the location of a trough. The limits are not clearly defined. There is a fulacht fia (MA111-104002-) c. 15m to S, and two burnt mounds (MA111-097----; MA111-098----) are located c. 85m to NW and c. 80m to NNE respectively.

• MA111-104002 Fulacht fia
  Description

  In average pasture, located on a gently W–facing slope bordering an expanse of flat reclaimed pasture and rush-grown, boggy ground which stretches to W–NW. A low, roughly kidney-shaped rise (c. 11.5m N–S; c. 13m E–W) with a central depression opening to W. The mound appears to have been partly levelled; it is highest and most clearly defined at S but elsewhere its exact limits area difficult to trace. An eroded section of the mound revealed a compacted concentration of stone fragments in black soil. There is a burnt mound (MA111-104001-) c. 15m to N, and two burnt mounds (MA111-097----; MA111-098----) are located c. 100m to NW and c. 95m to NNE, respectively.
