• MA119-007 Earthwork
  Description

  In level good pasture, originally part of the demesne of Mount Jennings House. Not shown on the 1838 OS 6-inch map; shown as a subcircular hachured feature (diam. c. 15m) on the 1915 edition. No visible trace at ground level. An oak tree and a birch tree may stand on the location. Compiled by: Jane O’Shaughnessy Date of upload: 31st May 2023

• MA119-028001 Enclosure
  Description

  In pasture, on level ground at the top of a S-facing slope. The location provides excellent views SE−SW over expanses of improved and damp pastureland. Roughly D-shaped area (17.7m NW−SE; 17m NE−SW) defined by a broad, low earth and stone bank (c. 3m; int. H 3m; ext. H 0.45m at NE; Wth 5.7m; int. H 0.55m; ext. H 1.25m at W), curving S−NNE. The bank is better preserved at S−NW, with a broad external slump compensating for a natural fall of ground. There is a break at NW. On the straight E side it is bordered by a field fence/property boundary (ext. H 1.5m), which appears to have partly truncated the original E-SE side of the enclosure. The interior is very slightly domed in profile, sloping down from a raised centre (diam. c. 6-7m) towards the perimeter, most noticeably at E and S. It was used as a children’s burial ground (MA119-028002-). This site was difficult to examine due to thick overgrowth. The enclosing bank is ringed with hawthorn, blackthorn and brambles, as is the field fence, which is also in parts piled with dead branches/field clearance debris. Ash and hawthorn trees with long grass and nettles obscure much of the interior. Compiled by: Jane O’Shaughnessy Date of upload: 23 June 2023

• MA119-028002 Children's burial ground
  Description

  In a rath (MA119-028001-). The interior of the rath was used for the burial of unbaptised babies. Several small, low moss-covered unshaped and uninscribed stones protrude from the ground. These appear to be gravemarkers. Due to dense overgrowth, they are difficult to see, and it was not possible to determine their density or any pattern in their layout. Compiled by: Jane O’Shaughnessy Date of upload: 23 June 2023

• MA119-030 Enclosure
  Description

  A circular enclosure (diam. c. 40m) is shown on the 1838 OS 6-inch map; it is not shown on later map editions, although a kink in a NE−SW field fence is indicated on the 1915 OS 6-inch edition, which probably preserved the NE arc of the enclosure. There is no visible trace of the enclosure at ground level; a modern bungalow with associated garden now occupies the location. Compiled by: Jane O’Shaughnessy Date of upload: 23 June 2023

• MA119-031 Enclosure
  Description

  A circular enclosure (diam. c. 20-25m) is shown on the 1838 OS 6-inch map; it is not shown on later map editions. There is no visible trace at ground level. It appears to have been located on a rise with a fall of ground to SW towards a stream/drain. There is a castle (MA119-032----) on the opposite, S side of the drain.
