• MA038-089001 Ringfort - rath
  Description

  In pasture, located on a low NE–SW ridge of elevated ground, overlooking an expanse of flat, wettish land to S–SW, which borders the Fiddaunglass River. The S boundary of the townland coincides with the river. Named ‘Lisheen’ on the 1838 and 1922 OS 6-inch map, this rath consists of a sub-circular area (54m N–S; 53.5m E–W) defined by a substantial, stone-faced bank (Wth 4.2m at WNW; 2m at NE; int. H 0.4m at NWW, 0.55m at NE; ext. H 1.4m at WNW, 0.55m at NE). The dry-stone facing is well preserved on the external face of the bank at W–N, and visible intermittently elsewhere. Remnants are also evident on the inner bank face. At E–SE the bank is truncated by or incorporated into a later linear property fence on a NNE–SSW axis, and another field fence abuts the rath at W. On the SW arc the bank is largely degraded to a scarp, but at SW–N it retains a pronounced external slope (max. ext. H 2m at SW), compensating for a natural fall of ground. The interior slopes down from centre to S–SW. Much of the space in the E half is taken up with a square enclosure used as a children’s burial ground (MA038-089002-). The enclosing bank is thickly ringed by ash trees, blackthorn, hawthorn and brambles, and is eroded in parts by animal burrows. A blackthorn thicket encroaches on the SW quadrant of the interior, and overgrowth also obscures the children’s burial ground. There is an enclosure (MA038-090----) 160m to NE, and a rath (MA038-091----) 115m to SE. Compiled by: Jane O'Shaughnessy Date of upload: 1 August 2019

• MA038-089002 Children's burial ground
  Description

  In the E half of a rath (MA089001), named ‘Lisheen’ on the 1838 and 1922 OS 6-inch maps. This children’s burial ground is indicated as ‘Infants’ Burial Ground (Disused)’ on the 1922 OS 6-inch map. It consists of a square area (9.5m NNW–SSE; 11.5m ENE–WSW) defined by a low, stony bank (W 2.3m; int. H 0.25m; ext. H 0.4m). The interior is largely obscured by blackthorn scrub, brambles and ferns. A few low stones, including one upright slab, which probably served as grave markers, can be seen in the N half, and stones can also be felt underfoot beneath covering vegetation.

• MA038-090 Enclosure
  Description

  In pasture, located on a low rise in undulating grassland bordered c. 300m to S by a small river, the Fiddaunglass, and by an expanse of lowlying boggy ground c. 300m to N. This enclosure is not shown on the 1838 OS 6-inch map, but is shown on the 1922 OS 6-inch map as a sub-circular enclosure (diam. c. 20-25m) truncated on its SE edge into a linear NE–SW field boundary. It has been levelled; a barely discernible, roughly circular undulation, overlain at SE by a field fence, is visible. There is a rath (MA038-089001-) and children’s burial ground (MA038-089002-) 160m to SW. Compiled by: Jane O'Shaughnessy Date of upload: 1 August 2019

• MA038-091 Ringfort - rath
  Description

  In a thicket of hazel trees, located on top of an elongated knoll, at its W end. The knoll forms an island of elevated ground surrounded by lowlying, flat wettish grassland, and is bordered on the S side by the Fiddaunglass River, which coincides with the S boundary of the townland. The rath is shown as a circular enclosure on the 1837 OS 6-inch map; it is not shown on the 1922 edition. Oval area (17.6m NNE–SSW; 26.9m WNW–ESE) defined by a scarp (ext. H 2m; Wth slope 4.8m at W). The enclosure encompasses the full width of the broad W end of the knoll, and utilises the contours of the steep natural slope at SE–W–NE to define and enhance the enclosing scarp. No upstanding bank remains. Stones protrude from the top edge of the scarp in parts. A gap (Wth 2.5-3m) in the scarp at ESE marks the original entrance. It faces the narrow spine of the ridge, allowing a gradually descent towards the ESE. The interior slopes down slightly from NW to SE. There is a souterrain (MA039-155) in the W half, indicated by three areas of surface collapse. Compiled by: Jane O'Shaughnessy Date of upload: 6 August 2019

• MA038-093 Enclosure
  Description

  In pasture, prominently sited on a small gravel ridge, in an area of rolling terrain. It is located adjacent to the E boundary of the townland which coincides with a canalised stream. Loughnapastia lake is 170m to NNE. Nephin Mountain looms in the distance at SW, with the Nephin Beg range defining the far horizon at SW-W. This possible barrow is named ‘Rathmarrick’ on the 1838 and 1922 OS 6-inch maps. It consists of a raised flat-topped circular area or platform (6.5m) defined on its outer edge by a stony bank (Wth 1.9m; int. H 0.5m; ext. H 0.65m, at SSW). The bank is evident as a low irregular jumble of sod-covered earth and stones. On the NW arc it has a steeper external slope, merging with the fall of ground (H 1.6m); both the external face of the bank and the ridge slope appear to have been scarped or cut away. It is ringed with hazel and blackthorn scrub and brambles. Compiled by: Jane O'Shaughnessy Date of upload: 6 August 2019

• MA038-155 Souterrain
  Description

  In the W half of a rath (MA038-091). A sunken or collapsed area (diam. c. 1m) is evident in the slope of the rath scarp at W. Several large stone slabs, which are tipping into it, appear to be displaced roof lintels of a souterrain. The souterrain may extend from here through the rath interior, as there is surface depression (2m E–W; 1.5m N–S; D 0.3m) 6m to E, from which a number of stones and slabs protrude, and c. 2m to NNW of that, is another irregular-shaped surface depression.

• MA038-157 Mound
  Description

  In pasture, located at the N end of an elongated N–S rise in gently undulating terrain. Good views, with Nephin Mountain dominating the skyline to SW. This monument is not shown on the 1838 and 1922 OS 6-inch maps, but is shown on the 25-inch plan as a circular hachured feature (diam. c. 10m). It has been levelled. A slight rise (diam. c. 10m) in ground level can still be discerned at the location. Compiled by: Jane O'Shaughnessy Date of upload: 16 August 2019

• MA038-188 Fulacht fia
  Description

  In rough pasture, on the N bank of a stream, named Fiddaunglass, sheltered by rising ground to N. A roughly circular, grass-covered mound (diam. 18m; H 0.7m at W, 1m at E) composed of heat-shattered stone fragments in charcoal-rich soil. A large stone protrudes from the top surface of the mound to N of centre. There is a slight depression at S; it is not clearly defined, but may indicate the location of a trough. A field drain clips the E edge of the mound, and an old E-W field bank intervenes between the mound and the stream which is 4m to S. This is one of a linear cluster of fulachtai fia/burnt mounds (see also MA038-189---- to MA038-197----) located along the course of the stream.
