• MA072-051 Ringfort - unclassified
  Description

  In rough, heather-covered pasture, located on a hill, with excellent views in all direction. Slightly raised circular area (25m NW–SE; c. 25m NE-SW) defined E–NNW by an earthen scarp (H 0.35-0.6m at NW, 1.4m at SE), best preserved E–SE where it is enhanced by the natural slope. Stones protruding in parts along the top of the scarp may be the remnants of wall footings (Wth c. 1.4m). At N–NE the scarp has been levelled and is discernible only as a slight undulation marked by differential vegetation growth. A field wall on a NNW–SSE axis crosses the NE side of the interior. Slightly SE of centre, and abutting the bisecting property wall, is a ruined sub-rectangular building (MA072-051001-), probably the vernacular house shown on the 1838 OS 6-inch map.

• MA072-051001 House - indeterminate date
  Description

  Within a rath (MA072-051----). A ruined sub-rectangular building (3.7m NE–SW; c. 7.6m NW–SE) is located slightly SE of centre within the rath, abutting a NW-SE field wall of relatively modern date, which extends through the rath. It is defined on the NE side by the field wall, on SE and SW by a ruined stone wall (H 0.75-1m), and is open at the NW end. It does not appear to be an ancient structure; it seems likely to be the ruins of a vernacular house, which is shown on the 1838 OS 6-inch map.

• MA072-052 Ringfort - cashel
  Description

  In rough pasture, located on a rise, utilising the natural fall of ground to N. Subcircular area (20m N−S; 25m E−W) defined by a drystone wall (Wth 1.3-1.5m; int. H 0.9-1m; ext. H 1.8m at N, 1.5m at S). The wall is roughly constructed of random medium-sized rubble, with a few larger stones and boulders in parts. It is in a rather dilapidated condition, with sections of collapse or slumping. It is incorporated into a system of field walls which radiate from it at N, NE, SE, S and W. Outside the enclosing wall at SW−NE there is a berm or terrace (Wth 2.6-3m) defined by a low scarp (H 0.6) on its outer edge. The interior has a slight slope down from centre to E. There is a light covering of blackthorn scrub throughout. A blocked up gap in the enclosing wall at E may be an original entrance. The current entrance is a break (Wth 3m) at W. A subrectangular annex or small field plot (11.8m NW-SE; 17.5m NE-SW) is appended to the enclosure wall at SE. It has a slightly raised level interior and is enclosed defined by a drystone wall (Wth 0.9m; int. H 0.3m; ext. H 1m). This may equate to a small subcircular feature shown abutting the E side of the enclosure on the 1838 OS 6-inch map. Compiled by: Jane O’Shaughnessy Date of upload: 20 April 2021

• MA072-053 Ringfort - unclassified
  Description

  In pasture, located on gently elevated ground, overlooking an expanse of lowlying pasture. This ringfort is shown the 1838 OS 6-inch map as a subcircular embanked enclosure, clipped at E by a N−S field fence; a D-shaped enclosure (c. 30m N−S; c. 20m E−W to fence), bordered on the straight side at E by a N−S field boundary, is shown on the 25-inch plan; it is not shown on the 1930 OS 6-inch edition. It has been levelled and there is no trace at ground level. According to local tradition, it contains a souterrain (MA072-053001-). Compiled by: Jane O’Shaughnessy Date of upload: 20 April 2021

• MA072-055 Children's burial ground
  Description

  In pasture, located on a hill, with excellent views. This children’s burial ground is indicated on the 1838 OS 6-inch map as a roughly rectangular area (c. 15-20m E−W; c. 10m N−S), annotated ‘Graveyard’; on the 1930 edition is shown as a subrectangular area (c. 18m NW−SE; c. 14m NE−SW), annotated ‘Children’s Burial Ground (Disused)’. The remains consist of a very slightly raised rectangular area (c. 10m NNE−SSW; c. 8m ENE−WSW) enclosed on the N, E and S sides by drystone field walls, and open on the W side, where a slight scarp (H 0.3-0.4m) is evident. A number of small low stones, possibly gravemarkers, protrude from the ground surface in the interior, but are largely obscured by blackthorn scrub and long grass. According to local information, burials of unbaptized babies took place here during the 1930’s, 40’s and 50’s. Compiled by: Jane O’Shaughnessy Date of upload: 5 May 2021

• MA072-075001 Ringfort - rath
  Description

  In pasture, located on a rise. There is a stream 55m to SW. Raised circular area or platform (30.6m N−S; 30.5m E−W) defined by an earthen bank (Wth 3.3m; int. H 0.3m at NNW, 0.5m at SSE; ext. H 1.6m at NNW, 1.45m at SSE), which is reduced to a scarp at SE−NW. The base of the platform is enclosed by a broad, shallow fosse (Wth 4m) with an external bank (Wth 4m at NNW, c. 2m at SSE; int. H 1.1m at NNW, 0.8m at SSE; ext. H 1.9m at NNW, 0.5m at SSE). The external bank is incorporated into a later field wall at E−SSW and is topped with heaps of stones. A break (Wth 3m) in the inner bank at NE may be an original entrance; a few stones edge the base of the bank terminals. A slight rise in the base of the fosse here may be the remnants of a causeway. No corresponding gap in the external bank is evident, but the external bank has been modified here. Ground level appears to be slightly higher in the NW part of the interior, and the surface is lightly strewn with stones. There is a souterrain in the S half of the interior. A field wall/property boundary on a WNE−ESE axis cuts across the centre of the rath. At NE a semi-circular area (10m NE−SW; 6m NW−SE) has been quarried out of the external slope of the rath platform. The rath is engulfed in a stand of hazel trees. Compiled by: Jane O’Shaughnessy Date of upload: 14 May 2021

• MA072-075002 Souterrain
  Description

  In a rath (MA072-075001-). An area of surface collapse (2.5m N−S; 2.3m E−W; D 1m at S end) is evident in the S half of the rath interior. At the deeper S end of the depression an opening (H 0.4m) reveals a subterranean passage (W c. 2m) with drystone walls and lintel roofing. Compiled by: Jane O’Shaughnessy Date of upload: 14 May 2021

• MA072-076 Ringfort - unclassified
  Description

  In pasture, on top of a hill with very good views This ringfort is shown on the 1838 OS 6-inch map as a circular embanked enclosure (diam. c. 20m), with a rectangular vernacular building abutting it at NE and another building to E of that; the enclosure and the two buildings are not shown on later map editions. The ringfort has been levelled. A gently domed rise (diam. top c. 19m E−W; c. 12m N−S) with broadly sloping sides is evident, with a field wall skirting the S slope. The field wall cuts into the slope, being almost flush with ground level on its N side, and having a steep drop on its S face (H 2m). The shallow curve (L c. 20-24m E−W) of the field wall may preserve the original S arc of the ringfort. A kink in a N−S field wall on the E side of the rise may mark the original location of the rectangular vernacular building shown on the 1838 OS 6-inch map. There is a local tradition of a souterrain (MA072-076001-) here. Compiled by: Jane O’Shaughnessy Date of upload: 14 May 2021

• MA072-076001 Souterrain
  Description

• MA072-077 Ringfort - rath
  Description

  In pasture, located on top of a hill, with very good views. Slightly raised oval area (32m N−S; 27.6m E−W) defined by an earthen bank (Wth 2.6m SSE, 3.4m at NNW; int. H 0.6m at NNW; ext. H 1.1m at SSE, 0.95m at NNW). The bank is low but well defined, with stones protruding intermittently along its inner face at NW and NE. It is incorporated into a later field wall on the SW arc. A low terrace (Wth c. 5m) defined on its outer edge by a low scarp is evident immediately outside the bank on the E half of the rath; it is possible that this may be the remnant of an outer enclosing element. There are narrow eroded breaks in the bank at N (Wth 1.2m) and NNE (Wth 1m). According to local information, there is a souterrain (MA072-077001-) in the N half of the interior; the location is marked by a shallow surface depression in an area of uneven hummocky ground.
