Recorded monuments

• MA062-033 Ringfort - rath
  Description

  In pasture, located on top of a ridge with a natural fall of ground to N. The monument consist of the W half of an originally circular rath. It is depicted as a D-shaped embanked enclosure on the 1837 OS 6-inch map, indicating that the E portion of the rath had already been removed by 1837. The extant remains consist of a slightly raised, D-shaped area (39.4m N–S; cord 22m E–W) defined on the curving side S–N by an earthen bank (Wth 3.8m; int. H 0.8m; ext. H 1.4m) with an external fosse (Wth 3.3m; D 0.35m). A field fence/property boundary defines the straight side at E. To E of the fence, no trace of the rath is evident at ground level; the ground surface here is somewhat sunken and it appears that this portion of the rath was quarried out. According to local tradition, there is a children’s burial ground (MA062-033001-) in the rath. The bank is ringed by hawthorn, and erosion by farm stock is evident in parts.

• MA062-033001 Children's burial ground
  Description

  In a rath (MA062-033). According to a local tradition that the interior of the rath was used as a children’s burial ground. Only the W half of the rath survives; the interior is level and grass-covered and no above ground evidence of graves is apparent. Compiled by: Jane O’Shaughnessy Date of upload: 25 November 2020

• MA062-034 Ringfort - rath
  Description

  In pasture, built against the slope of a low natural rise, overlooked to N by a hill. Raised, roughly circular (diam. c. 22m NE–SW) defined by an earthen bank (Wth 2.8m at NE, 4m at SW; int. H 0.2m at NE, 0.55m at SW; ext. H 1.2-1.4m). The bank is low internally but has a well defined external scarp. To E–SE the exterior face of the bank is more noticeably slumped and this may point to the location of an original entrance. The interior is largely inaccessible due to dense thorn bushes and brambles. Beneath the overgrowth, there appears to be a slight rise in interior ground level to N of centre. The perimeter is also ringed with overgrowth. Traces of cultivation ridges are visible in the surrounding field. Compiled by: Jane O’Shaughnessy Date of upload: 25 November 2020

• MA062-035 Enclosure
  Description

  In pasture, located on top of a narrow E−W ridge at the break of slope on the N side. There are extensive views to N−NW where the ground falls away precipitously to a flat expanse of bog. A stretch of bog also borders the S side of the ridge. This possibly a rath is shown on the 1919 OS 6-inch map as a circular enclosure (diam. c. 35-40m). It has been levelled. The outline can still be traced on the N arc as a slight scarp (H 1.3m), which merges with the natural fall of ground, and elsewhere as a slight surface undulation.

• MA062-144 Fulacht fia
  Description

  In an E–W peat basin bordered to N and S by drier higher ground. An E–W field drain lay 5m to S, possibly following the line of an earlier stream. This fulacht fia (designated Sonnagh 3) was discovered during archaeological testing and subsequently fully excavated in advance of the construction of the N5 Charlestown bypass (Ministerial direction no. A020/003; Registration no. E23345) (Gillespie and Kerrigan 2010, 74-76.). The roughly oval mound (10m by 6m; H 0.35m), which was enveloped in peat, was composed of compacted burnt stone in a charcoal-rich peaty matrix interspersed with lenses of peat. A trough, cut into the underlying peat, was found beneath the SW edge of the mound. It consisted of a sub-circular pit (diam. 1.25m; max. D 0.4m), with concave sides and a flat base. There was a single split alder plank in the base of the trough, held in position by two wooden rods, one at each end. A sample of alder charcoal from the trough fill produced a radiocarbon date of 2867-2497 Cal. BC (GrN-30754), indicating usage in the late Neolithic period. (Gillespie and Kerrigan 2010, 74-76.)

• MA062-145 Fulacht fia
  Description

  Located on the E edge of an E–W peat basin, bordered to N and S by drier higher ground. An E–W field drain lay 3m to S. This fulacht fia (designated Sonnagh IX) was discovered and fully excavated in advance of the construction of the N5 Charlestown bypass (Ministerial direction no. A020/076; Registration no. E23358) (Gillespie and Kerrigan 2010, 92-94). The crescent-shaped mound (11m E–W; 9.5m N–S; max. H 0.5m), which was enveloped in peat, was composed of heat-fractured sandstone in a matrix of charcoal and peat. A depression on the SE side of the mound enclosed an oval trough (1.8m N–S; 1.1m E–W; D 0.4m) with vertical sides and a flat base. The trough was cut through the peat into the underlying marl to access the local water table. Two split alder timbers lay in the base, and two hazel stakes and a willow stake were driven into the marl at the N, S and NW ends of the trough. The fill included a dense layer of moss and fragmented hazel wicker rods interpreted as the possible remains of a wicker lining used to filter the water. The jaw bones of a domestic pig were also recovered from the fill. Eight pieces of wood, including a split pine log, lay immediately to N and S of the trough. A coarse grey chert blade was recovered from the mound. A sample of alder charcoal from the basal fill of the trough was dated to 3645 ± 40BP; 2134-1919 Cal. BC (GrN-30759), placing it in the Early Bronze Age. (Gillespie and Kerrigan 2010, 92-94) Compiled by: Jane O’Shaughnessy Date of upload: 26 January 2021
