Recorded monuments

• SL002-019 Ritual site - holy well
  Description

  In rough pasture, at the base of W-facing slope, on the SW side of Dernish Island. The shoreline is c. 20m to W, bordered by a vertical scarp (H 2m) which drops from the land to a stony shore. This holy well is not shown on the 1837 OS 6-inch map; it is indicated as ‘Tober Patrick’ on the 1912 edition. It consists of a spring well, which rises, at the base of the slope in a small subcircular hollow (diam. c. 1m), amidst a random scatter of large stones and boulders. There is no evidence of walling or a formal structure enclosing the well. It is partly engulfed in overgrowth. From here, the water flows as a stream in a shallow, stony gully towards the shore. At the shoreline, c. 20m SW of the holy well, where the stream crosses the vertical land-edge scarp (H c. 2m), there is a setting of three large upright slabs at the top of the scarp, and at the base of the scarp, on the shoreline, a 2m wide channel is faced with boulders. The purpose of these features is unclear; they appear to be relatively late in date, and it is unclear if they relate in any way to use of the spring as a holy well. There is a fulacht fia (SL002-055----) 8m to WNW of the holy well. Compiled by: Jane O'Shaughnessy Date of upload: 31 July 2017

• SL002-037002 Burial
  Description

  An extended female inhumation in a slab-lined grave was found in 1992 on Dernish Island. Eight roughly circular flat stones formed a mandola-like ring of glory around the skull of the skeleton. It is considered to date to the early 1st millennium AD. (Buckley, Buckley and McCormick 2002). Compiled by: Paul Walsh Date of upload: 6 August 2015

• SL002-055 Fulacht fia
  Description

  In rough, damp pasture, at the base of a W-facing slope on the SW side of Dernish Island, 8m WNW of a spring well/Holy well (SL002-019----). The shoreline is 10m to W, bordered by a vertical scarp (H 2m) which drops from the land to a stony shore. This fulacht fia is evident as a very low, poorly defined sod-covered mound (6m N−S; 4m E−W; H 0.2-0.3m at E, 0.4m at W) of angular stone fragments in dark grey/black soil. It appears to have a shallow crecentic shape, curving around a slight hollow (Wth c. 1-1.5m) on the E side. Its compact, firm surface distinguishes it from the surrounded soft, damp ground.

• SL002-056 Hut site
  Description

  In rough, pasture, located on a terrace on a SW-facing slope, on the SW side of Dernish Island. Ground falls away at W−SW for c. 15-20m to the shoreline. Roughly oval, sunken area (c. 6m E−W; c. 4.5m N−S) enclosed by a sod-covered bank. The interior is sunken to a depth of c. 0.4m below exterior ground level. Stones protrude from the bank in parts. The N arc of the bank (W 1-1.4m, int. H 0.6m; ext. H 0.2m at N) is quite well-defined, but at SE the bank appears more irregular, and varies in width (Wth 1.5-2.5m), with a broadly slumped, possibly disturbed, internal face. At SW the bank takes the form of an inward-facing scarp, which does not have a clearly defined external edge, but appears to merge with the natural slope. There are breaks (Wth 0.4-0.5m) in the bank at W, E and SSE; those at W and E may be the result of erosion by farm stock. The break at SSE may be an entrance feature; the E terminal of this gap has a linear extension (L 2m) to S, mirrored on the W side by a rise from which a large stone protrudes. The remains as a whole are low-profile and rather irregular, and are covered by ferns and brambles. This may be some form of hut, date and exact function uncertain.

• SL002-057 Midden
  Description

  Exposed in section in the land-edge cliff on the extreme SE side of Dernish Island. The vertical sand cliff (H c. 2-3m) drops to a strip of sandy beach, bordering a narrow tidal channel (Wth c. 250m) which separates the island from the mainland. A thin layer (L c. 2m) of sea shells, in a matrix of grey sand, is visible in the upper levels of the section face at a height of c. 2m above the shoreline. The sod-covered top of the cliff is partly slumped, and part of the midden layer may be displaced as a result. Compiled by: Jane O'Shaughnessy Date of upload: 1 August 2017
