• CL002-030001 Field system
  Description

  At the N end of a narrow valley (‘Rathborney Valley’) in pastureland, between Gleninagh ‘Mountain’ and Cappanawalla Hill. A complex series of field-systems, mostly post-dating but also potentially contemporary with and pre-dating a cashel (CL002-030002-), extend across the valley floor and up on to the karst to the W and N. Field survey in 1997 noted at least three phases of walls, old meandering walls (Wth 3m; H 0.4–0.6m), later but still possibly pre-famine walls (Wth 2m; H 0.5–0.7m) and modern strip walls. There are particularly dense concentrations of field boundaries abutting the W side of the cashel and centred around several post-medieval houses at the base of the N exit of the valley, c.180m NE of the cashel. Many of the earlier two phases of walls are not depicted on the 1842 or 1915 eds. of the OS 6-inch maps and there are at least elements within both concentrations that fit best with Plunkett Dillon’s (1985) and later writer’s (Jones, Carey and Hennigar 2011; Jones 2016) tumble walls. This would suggest that they are contemporary with the later medieval use of the cashel. Support for this might be taken from a pollen core taken from Poulacapple bog c. 4km to the S (Jeličić and O'Connell 1992) that suggested that locally there was increasingly intensive arable farming from c. 1000 AD until a shift to wetter conditions sometime before 1650 AD. There are two other complex field-systems containing elements of potential antiquity in Rathborney Valley, CL002-075002- in the NE corner and CL002-033001- along the E side. Each of these also encompasses one or more enclosures or ringforts. These may once have extended across the fertile valley floor, and essentially formed one or several interconnected field systems with CL002-030001-, but clearance and reorganisation of the fields between the 1842 and 1915 eds. of the OS 6-inch maps and the inclusion of strip fields within these since the 1915 ed. have removed any visible trace.

• CL002-030002 Ringfort - cashel
  Description

  At the N end of a narrow valley of pastureland between Gleninagh ‘Mountain’ and Cappanawalla Hill. A path rising to the N gives access over saddle between the two hills to the coast and improved pastureland runs S down the valley from the site. Listed as ‘Enclosure’ in the SMR (1992) and the RMP (1996). Hachured on the 1842 and 1915 eds. of the OS 6-inch maps and on Robinson’s map (1977). A large subcircular enclosure (int. dims. 66m N–S; 62m E–W) defined by a tumbled and partly grass-covered stone spread, traceable for its full course, with surviving inner and outer facing-stones at E (wall Wth 2.5m). A well-preserved stone-lined and outwardly splaying entrance (Wth on outer face 2.7m; Wth on inner face 2.1m) survives at SSE. A later field wall overlies the cashel wall from S to NNW. Westropp (1915, 62) noted that this ‘ring-wall’ was of unusually large size with battered walls (H 6-7ft [1.8-2.1m]) constructed of large well-fitted blocks. A midden (CL002-030003-) and the ruins of two buildings (CL002-030004- and CL002-030005-) are located S of the centre in the interior. A field system (CL002-030001-) of at least three phases (Gosling 1991, 88) crosses the interior and extends N, S, E and W. The field systems extend as far as but not visibly into the improved strip fields to the S, suggesting that there their visible traces have been removed. Another enclosure (CL002-075001-) and field system (CL002-075002-) are located c. 450m WSW, on the opposite side of the valley. These are also only visible outside the strip fields reinforcing the probability that such remains extended across the valley floor. The strip fields were already in existence in 1970, when the Cambridge aerial photos were taken (CUCAP BDM048–050 and 057).

• CL002-030003 Midden
  Description

  At the N end of a narrow valley of pastureland between Gleninagh ‘Mountain’ and Cappanawalla Hill, in the interior of a large cashel (CL002-030002-). A ‘shell midden’ was recorded in this cashel (pers. comm. T. Coffey, SMR file) and listed in the RMP (1996). There was no visible trace of the midden when the cashel was inspected in 1997. Two house sites (CL002-030004- and CL002-030005-) are located within the cashel. Compiled by: Mary Tunney and Ros Ó Maoldúin Date of upload: 9 December 2020

• CL002-030004 House - indeterminate date
  Description

  At the N end of a narrow valley of pastureland between Gleninagh ‘Mountain’ and Cappanawalla Hill, SE of centre in a large cashel (CL002-030002-). Not listed in the SMR (1992) or the RMP (1996). A partially obscured rectangular or subrectangular building (traceable L 8m E–W x 4m N–S) defined by grassed-over stone walling (Wth 2.4m; H 0.3m). A field wall is built over its W end and collapsed stone covers its E end. A second building (CL002-030005-) within the cashel is c. 23m WSW and a shell midden (CL002-030003-) was noted in 1994 (pers. comm. Tom Coffey, SMR file).

• CL002-030005 House - indeterminate date
  Description

  At the N end of a narrow valley of pastureland between Gleninagh ‘Mountain’ and Cappanawalla Hill, in the SW quadrant of a large cashel (CL002-030002-). Not listed in the SMR (1992) or the RMP (1996). An oval building (int. dims. 6m N–S; 4m E–W) defined by tumbled stone spread (Wth 2.5m; H0.5m). A second building (CL002-030004-) is c. 23m ENE, SE of the centre of the cashel and a shell midden (CL002-030003-) was noted within the cashel in 1994 (pers. comm. Tom Coffey, SMR file).

• DU002-010 Megalithic tomb - passage tomb
  Description

  In a field of tillage near the shoreline. Shown on Duncan's map (1821) as a 'moat'. Located on headland north of Lowther Lodge. Extensive views of the coastline up to the Mourne Mountains to north, Bremore tombs to south. Area c.20m EW x 20m NS of stones, slightly elevated in a field of no stone. Some stones appear water rolled (majority >0.30m diam.) granite, sandstone and smaller quartz stones. Local tradition of this being the site of a tomb-quite a lot of flint retrieved from these fields. A miniature stone axe was found in the immediate vicinity (pers coms. Kieran Campbell).

• DU002-023 Quay
  Description

  Harbour built c. 1760 (Cronin 2010, 34) depicted on the 1837 ed. Osi 6-inch map located 90m to the NE of Lowther Lodge.  An entry in 'The Farm Diary of Lowther Lodge Balbriggan 1803-1822' dated November the 5th in 1806 recorded that a 'very large stone brought by Mr. Lowthere many years ago from the mound at Newhaven and was lying on the strand was brought by two horses in the machine and put as a coin (sic) to the left hand corner of the stairs going down to the quay' (Balcombe 2008, 47). A second entry in the diary dated October 17th, 1818 recorded that; 'A boat load of large fillers was brought from Newhaven' (ibid., 91).  This suggests the possibility that kerbstones from the passage tomb (DU002-001002-) at Bremore were used in the construction of the pier. A 2010 report on the coastal architectural heritage of Fingal commissioned by Fingal Co. Co. recorded that; 'the remains of a second rubble pier, which is not listed in the RMP, are located on the stretch of the Knocknagin shoreline to the north of Bremore headland. This pier was associated with the Lowther family who may have arrived from Cumbria in the 17th century' (Cronin 2010, 10).    Compiled by: Caimin O'Brien based on details provided by Ian Lennon.

• DU002-025 Quarry
  Description

  Small irregular-shaped quarry (approx. dims. 30m E-W x 20m N-S) on S side of field field boundary depicted on the 1837 ed. OSi six-inch map.  Area depicted as a tree plantation on the last edition of the OSi six-inch map.  Area of old quarry visible as a tree covered area in tillage field on the 2013-18 MapGenie orthoimage.   Compiled by: Caimin O'Brien

• LE037-013001 Burnt mound
  Description

  Situated on a fairly level landscape. First identified in centre-line testing (05E0983) for a new line of the N4 (O’Connor et al. 2005, 37), and later fully resolved (E003305) as a part of Moher 5. This is a spread of burnt sandstone (dims 3.8m x 3m; max. D 0.08m) in a natural depression, from which a fragment of chert debitage was recovered. Burnt mound (LE035-013002-) is c. 12m to the ESE.

• LE037-013002 Burnt mound
  Description

  Situated on a fairly level landscape. First identified in centre-line testing (05E0983) for a new line of the N4 (O’Connor et al. 2005, 37), and later fully resolved (E003305) as a part of Moher 5, which was only partly excavated as most of it lay outside the road-take. It consisted of a spread of broken and burnt stone (dims 4m x 3.7m, max. D 0.12m) overlying peat (dims 4m x 3.7m; T 0.13) which in turn overlay a spread of silty clay over the natural. A sample from the peat produced a C14 date of 3916 ± 82BP (2620-2140 cal. BC), on the cusp of the Late Neolithic and the Early Bronze Age. Burnt mound (LE035-013001-) is c 12m to the WNW.
