## Recorded monuments (Sites and Monuments Record, National Monuments Service)

- MA072-082: Ringfort - cashel, https://heritagedata.maps.arcgis.com/apps/webappviewer/index.html?id=0c9eb9575b544081b0d296436d8f60f8&query=18a4b61b268-layer-9%2CSMRS%2CMA072-082----. In pasture, located at the W end of a ridge, with a steep fall of ground at S−SW and a more gradual, undulating slope at NW-N. The location provides good views, especially to S–W. This cashel consists of a slightly raised circular area (32.4m N–S; 32.3m E–W) enclosed by a ruined drystone wall, incorporated into a later system of field walls. At NE−S the external face of the enclosing wall survives to a height (H 0.8m–1m) of between four to seven courses of horizontally laid slabs and stones, with larger slabs used in the basal course. It appears to forms a facing on a scarp, and the top of the wall does not rise above internal ground level. At S the wall incorporates a single large boulder (Wth c. 1.4m; H 0.7m) that breaks the courses. At SSW–W the external wall-face is reduced to a single basal course of large boulders and slabs, and at W–N drystone walling (Wth 1.2m; ext. H 1.2-1.5m) of small and medium-sized stones, with a basal course of large stones, rests on a low earthen scarp (H 0.5m) -here the wall has a low, sod-covered internal stony lip (Wth 1.2m; int. H 0.5m). A gap (Wth 1.4m) in the wall at E may be the original entrance. It is flanked by rough walling/large stones. Extending for a short distance from the gap into the interior is a linear depression or slightly sunken area (Wth c. 1.4m). Outside the gap there is a grass-covered rise (Wth 4-5m) incorporating boulders and field clearance debris. Field clearance heaps are also piled against, or close to the cashel wall at NE and SE. A property wall, on a roughly N–S axis, bisects the cashel interior to E of centre. Another field wall bisects the W half of the interior roughly centrally, extending to WNW from the N−S property wall. To E of the N−S property wall, the interior shows evidence of disturbance, and is partly obscured by hawthorn bushes and brambles. There is a local tradition of a souterrain (MA072-082001-) in this part of the cashel. To W of the property wall, the interior is level and grassy. At WNW there is a large, ground-fast boulder. A large slab leans against the W side of the boulder; the base of the slab rests in a shallow hollow. Compiled by: Jane O'Shaughnessy Date of upload: 1 May 2021
- MA072-082001: Souterrain, https://heritagedata.maps.arcgis.com/apps/webappviewer/index.html?id=0c9eb9575b544081b0d296436d8f60f8&query=18a4b61b268-layer-9%2CSMRS%2CMA072-082001-. Located in a cashel (MA072-082----). There is a local tradition of a souterrain in the E half of the cashel: Two flat stones, possibly roof slabs, were said to have been exposed on the surface in the past, but were covered over and are not visible now.

---

Everytownland reads the registered freehold land and the statutory boundaries of Tailte Éireann, the national zoning, planning file and heritage records of the Department of Housing, Local Government and Heritage, and the Residential Property Price Register. A parcel is the land of a title, not an address. The owner's name is in the Land Registry of Tailte Éireann: a copy of the folio can be ordered on landdirect.ie, for a fee; this site names no owner. A price is the price recorded for a past sale, not a valuation.
