• RO021-042009 Pitfield
  Description

  Noted on aerial photograph (ACAP: V 260/17), and situated on a level landscape. An area of c. 6 ha (c. 15 acres) contains c. 20 oblong pits (dims c.10m x c. 3m; D 0.3m) placed c.30m apart but no regular alignment is detectable. Compiled by: Michael Moore Date of upload: 24 August 2010

• RO021-042010 Road - road/trackway
  Description

  On an undulating landscape of the Rathcroghan plateau. A slight hollow (Wth c. 3m; D c. 0.2m) can be seen intermittently bisecting ceremonial enclosure (RO021-042011-) on the S side of a WNW-ESE field wall. It has been suggested (Knox 1914a, 6 map) that it connected with the roadway (RO022-057021-) c. 1km to the E through the short section (RO022-057078-) c. 500m to the E. Compiled by: Michael Moore Date of upload: 24 August 2010

• RO021-042011 Ceremonial enclosure
  Description

  On an undulating landscape, including within it two slight NE-SW ridges on the Rathcroghan plateau. The cropmark of a large subcircular enclosure (diam. c. 250m NE-SW; c. 230m NW-SE) is recorded on aerial photographs (Waddell 1983, 35,38). The perimeter can be seen in interrupted sections as a slight fosse (Wth c. 2m; D 0.2m), with traces of an inner bank (Wth c. 10m) at SE (Waddell 1983, 35, No. 24; Waddell 1988, 8). It is bisected by a road (RO012-042010-) and the possible barrow (RO021-042012-) is inside the perimeter at E. (Waddell et al. 2009, 55-8) Compiled by: Michael Moore Date of upload: 24 August 2010

• RO021-042012 Barrow - ring-barrow
  Description

  On a gentle E-facing slope inside the perimeter of ceremonial enclosure (RO021-042011-) at E. Circular grass-covered hollow (diam. c. 8m; max. D 0.4m at W). Herity (1983, 132) suggests that this is a ring-barrow, but Waddell (1983, 35) regards it as a quarry pit. (Waddell 2009, 57) Compiled by: Michael Moore Date of upload: 24 August 2010

• RO021-042014 Road - road/trackway
  Description

  On a gentle SW-facing slope of the Rathcroghan plateau. Oriented NE-SW (L c. 700m), its NE end is aligned tangentially on the SE edge of Rathandarve (RO022-057004-) although stopping c. 200m short of it. At the NE end it is visible as a grass-covered carriageway (Wth 5m) bordered by an earthen bank (Wth 2m; int. H 0.2m; ext. H 0.4-0.6m) and outer drain (Wth of base 2m; D 0.2m) at NW and an earthen bank (Wth 4m; int. H 0.2m; ext. H 0.7m) and drain (Wth of base 2m; D 0.5m) at SE. At the SW end it is visible as a raised grass-covered strip (Wth 8m) with traces of outer drains (Wth 3-4m; D 0.1m) at either side. A fragment of the road can be seen near ring-barrow (RO021-042020-) c. 800m to the SW. (Waddell 1983, 28) Compiled by: Michael Moore Date of upload: 24 August 2010

• RO021-042015 Linear earthwork
  Description

  Towards the bottom of a gentle SW-facing slope. The name is derived from a local tradition that the linear features were made by a racing wild pig digging its tusks into the ground. The Northern Mucklaghs are two parallel grass-covered earthen banks aligned ENE-WSW and curving slightly to the N at either end (L c. 150m). The N bank (Wth of base 11.2m; H 1.8m at S; H 2.8m at N) is flat-topped (Wth 2m) and separated by a berm (Wth 3.6m) in which a drain has been dug from the S bank (Wth of base 11.2m; H 2.2m at N; H 3.2m at S). The Southern Mucklaghs (RO021-042016-) are c. 70m to the S, and barrow (RO022-057027-) is c. 120m to the NE. Rather than being linear earthworks extending over the landscape as boundaries, the two Mucklaghs may have been an attempt to create large ceremonial enclosures, one within the other. These would have been the largest ever created (int. diam. c. 500m; ext. diam. c. 1km) if they had been completed. (Knox 1914, 27-8; Herity 1983, 131; 1984, 138; Waddell 1983, 33; 1988,15; Waddell et al. 2009, 89-90) This is a National Monument in state ownership: No. 473 See the attached view (002) looking along the earthworks to the WSW and the distant view from the SW (003) with the northern Mucklaghs on the left.

• RO021-042016 Linear earthwork
  Description

  Towards the bottom of a gentle SW-facing slope. The name is derived from a local tradition that the linear features were made by a racing wild pig digging its tusks into the ground. The Southern Mucklaghs consist of three parallel grass-covered earthen banks aligned NE-SW but curving slightly to the N at either end and running across the slope (total L c. 210m), terminating just N of the pond called Caldra at SW. The N bank (L c. 180m; Wth of base 8m; H 1.3-1.4m) has four breaks and is separated by a berm (Wth 2m at NE to c. 12m at SW) from the middle bank (L c. 210m; Wth of base 7.8m; H 1.6m) which is flat-topped (Wth 1.7m) and has four breaks opposite those in the N bank. There are traces of a third bank (L c. 180m; Wth c. 6m; H c. 0.3m) with some breaks which is separated from the W end of the S bank by a berm (Wth c. 5 - 10m). The Northern Mucklaghs (RO021-042015-) are c. 70m to the N, cashel (RO021-042017-) is c. 150m to the W, and ring-barrow (RO022-057027-) is c. 150m to the NNE. Rather than being linear earthworks extending over the landscape as boundaries, the two Mucklaghs may have been an attempt to create large ceremonial enclosures, one within the other. These would have been the largest ever created (int. diam. c. 500m; ext. diam. c. 1km) if they had been completed. (Knox 1914, 27-8; Herity 1983, 131; 1984, 138; Waddell 1983, 33) Intensive survey, including geophysical methods, suggests that the third slighter bank, being on a different course, may pre-date the other two that could have achieved their present form as late as the Middle Ages. Evidence of a possible Neolithic house site (RO021-042049-) just inside the third bank was recovered through intensive magnetic gradiometry.

• RO021-042017 Ringfort - cashel
  Description

  On the floor of a WNW-ESE valley in an area of rock outcrop. Subcircular grass-covered area (int. dims 35m N-S; 31.7m E-W) defined by the intermittently visible grass-covered foundations of three stone walls (Wth 1.3-2m) placed 2-4m apart, although only two walls can be traced at S (max. ext. dims 54.4m E-W; 50.6m N-S). There is no identifiable original entrance. A small rectangular enclosure or annexe (RO021-042018-) (dims c. 30m N-S; c. 20m E-W) defined by a grass-covered stone spread (Wth c. 1-2m) is attached to the SE, and relict field walls (RO021-042019-) (L c. 100m) attach to the perimeter of the cashel at N, E, S and NW.

• RO021-042049 House - Neolithic
  Description

  Towards the bottom of a S-facing slope, and just N of the third, most southerly and slightest of the southern Mucklagh banks (RO021-042016-), although the relationship is probably fortuituous. Intensive geophysical survey recorded evidence of a rectangular area (dims. c. 10m NE-SW; c. 7m NW-SE) with some internal features defined by what may be a slot-trench (Wth c. 2m), the N angle of which appears to be destroyed by or buried deeply beneath the central bank of the southern Mucklaghs.

• RO022-057004 Enclosure - large enclosure
  Description

  Around a natural knoll (dims c. 32m NE-SW; c. 28m NW-SE; H 2m at SE to 3m at NW) on a gentle S-facing slope of the Rathcroghan plateau. Circular grass-covered area (int. diam. c. 74m) defined by an earthen bank (at E: Wth 7.4m; int. H 1.4m; ext. H 2.2m) and outer fosse (at W: Wth of top 9.3m; Wth of base 4.5m; D 0.4m), which is obscured by a modern road bank E-S (max. ext. diam. c.110m N-S). The probable entrance (Wth 6m) is at SSE. Geophysical testing failed to record evidence of any internal structures or activities, apart from what might be an episode of burning on the summit of the knoll (Waddell et al. 2009, 58-66). Described as a possible ring-barrow (Herity 1983, 132; 1988, 131, Glenballythomas 3).

• RO022-057021 Road - road/trackway
  Description

  On Rathcroghan plateau and its E-facing slope. Running W from the well of Tobar Caoch (RO022-057053-) to S of Rathcroghan mound (RO022-057010-) (L 1.2km), and perhaps as far as the N edge of Rathnadarve (RO-022-057004-) (L c. 1.8km) through the road fragment (RO022-057078-). At the E end it truncates rath (RO022-057055-) and here the carriageway (Wth 12m) is defined by earthen banks (Wth 2.2-2.6m; int. H 0.6-0.7m; ext. H 0.1-0.2m). Just E of the deserted settlement (RO022-057070-) the N bank overlies earthwork (RO022-057088-). The road runs through the settlement, and house (RO022-057086-) is incorporated into the N bank. About 120m W of the settlement traces of a branch road turn N (L c. 70m), although it is closed off by a low bank. The road continues to the Tulsk-Bellanagare road (N5) as a carriageway (Wth 8m) defined by earthen banks (Wth 3m; H 0.2-0.5m) on both sides. It does not visibly survive W of the N5, but its N boundary may be incorporated into the field wall and townland boundary running W, to the S of the Rathcroghan mound, where the two ring-barrows (RO022-057015-) and (RO022-057016-) would have been overlain by it, and they undoubtedly pre-date the road. It also disregards and post-dates the ceremonial enclosure (RO022-057012-).

  On the S-facing slope of Rathcroghan plateau. Described as a mound (diam. c. 20m) with the entrance to souterrain (RO022-057029-) in the interior (Ferguson 1872, 117). It is not visible at ground level, and a NW-SE lane lies just N of the souterrain entrance. Ring-barrow (RO022-057025-) is c. 120m to the NW. (Knox 1914, 35; Herity 1983, 132, 1987, 138; Waddell 1983, 33) Geophysical survey recorded anomalies around the entrance to the souterrain suggesting a circular area (diam. c. 17m), but no evidence of an enclosing bank or fosse, or of any internal structures was recorded.

• RO022-057029 Souterrain
  Description

  On the S-facing slope of Rathcroghan plateau, inside earthwork (RO022-057028-). It was considered to be the entrance to the underworld, and the residence of Morrigan, a pagan goddess of war, as well as being the dwelling of magical pigs, cats and other animals and spirits who emerged at Samhain or Halloween, the feast of the dead. (Gormley 1989, 12-14) A stone-built and lintelled passage (dims 10.5m NNW-SSE; Wth 0.75-1.4m; H 1-1.8m) is partly rock-cut and descends from the blocked entrance at SE through a trapdoor at its N end to a natural cave (max. dims 37m NNW-SSE; Wth of base c. 0.7-2.5m; max. H c. 7m). A second passage which joins the main passage close to the blocked entrance is now destroyed in its central part but allows access to the main passage through a short section (Wth 1.35m; H 0.9m) aligned ENE-WSW (L 2m) which serves as the present entrance to the whole structure. The original end of this passage is preserved as an inaccessible undifferentiated passage end (dims c. 1.5m x 1.5m) in the field bank c. 3m W of the present entrance to Oweynagat, although this has been interpreted as a separate souterrain (Waddell et al. 2009, 81-3). There is an ogham stone (RO022-057030-) at the junction of the two passages, and another (RO022-057084-) is at the SE end of the main passage. (Herity 1983, 132; 1987a, 138, Glenballythomas 17; Waddell 1983, 33, No. 21; 1988, 13-4; Condit and Moore 2003) This is a National Monument in state ownership: No. 473 See the attached view looking towards the present entrance with the ogham stone (RO022-057030-) in the roof.

• RO022-057035 Concentric enclosure
  Description

  In a slight fold on the S-facing slope of Rachcroghan ridge. Named 'Relig na Riogh' and described as a cemetery by Charles O'Conor of Belanagare (1753, 129), this identification was followed by J. O'Donovan in 1837 who described it as the Royal Cemetery of Connaught (O'Flanagan 1931, vol. 1, 85), and others (Gormely 1989, 10). Investigations of the interior had been undertaken by Charles O'Conor of Mount Allen c. 1830 when the souterrain (RO022-057036-) was opened, and later investigations conducted in 1913 when the remains of post-medieval houses were uncovered demonstrating that it was not a cemetery (Macalister 1928, 179). Circular grass-covered area (int. diam. 102m N-S; 99m E-W) defined by a stone spread (Wth 2-5m; H 0.4-1m) with internal and external facing-stones sometimes visible (original Wth c. 1.5m), and an outer fosse (Wth of top 4m; D 0.6m) SW-NW. There is a raised central platform (diam. 65m N-S), perhaps the remains of a rath (RO022-057077-), defined by a scarp (H 0.3-0.5m) N-S-W, with the entrance to souterrain (RO022-057036-) in the scarp at W.

  Description

  There is an ogham inscription on a lintel at the extreme E end of the original passage of the souterrain (RO022-057029-), know as Oweynagat ('the cave of the cats'), which is part of the larger complex of monuments at Rathcroghan. It has been interpreted and tentatively reconstructed as: [MA]Q RẸG[A]S MU[COI]. A second ogham stone (RO022-057030-) is in the same souterrain. (Ferguson 1864-6, 155-70; Rhys 1898A, 230-2; Rhys 1898B; Knox, 1914, 35; Herity 1983, 132; 1987, 138; Waddell 1983, 33; Condit and Moore 2003) This is a National Monument in state ownership: No. 473.

• RO022-057092 Settlement cluster
  Description

  In a slight fold on the gentle S-facing slope at Rathcroghan. An area of c. 2.5 ha (c. 6 acres) within field system (RO022-057032-) and N of the concentric enclosure Relig na Rí (RO022-057037-) contains at least six houses. They appear as grass-covered areas (ext. dims. c. 11m x c. 5m to c. 19m x c. 9.5m) defined by low earthen banks (Wth 1-2.5m; H up to 0.5m) or low scarps, and are integrated with the field banks. Only one has two rooms, but the three largest have entrances in each long wall, while two have no apparent entrances. No street or road can be identified, but the field system is at its most complex here with numerous small paddocks (dims. c. 20m x c. 30m). Three houses placed close together are aligned N-S while the three others are aligned E-W and more dispersed. The house (RO022-057037-) at Relignaree (RO022-057035-), and the other houses investigated there in 1913 (Waddell 1983, 26), are outliers of the settlement.

• RO022-057095 Road - road/trackway
  Description

  Located at the W side of a slight N-S rise on the S-facing slope of Rathcroghan. It was first identified by G. Dempsey from Air Corps aerial photographs (date c. 1955) as two parallel and closely spaced earthen banks. The banks (Wth c. 2-3m; max. H c. 0.3m) are located c. 3-4m apart and survive in interrupted sections (max . L c. 115m) with the S end curving to the W as do the Mucklaghs (RO021-042015-; RO021-042016-) c. 500-700m to the SSW. The E bank is more prominent and has a distinct gap at one point, but the small scale of these features suggests that they are part of a roadway. The roadway is unconnected with the road (RO021-042014-), the N end of which is c. 250m to the W of the S end of this feature.

• RO022-057096 Enclosure
  Description

  Located towards the bottom of a gentle S-facing slope and c. 77m WNW of Cloghnagcorp (RO022-057043-) Two low lying rectangular enclosures are outlined by a series of stones. The E enclosure (dims c. 8m E-W; c. 7m N-S) has a small annex (dims c. 3m x c. 3m) to the N. Just to the W is an oblong enclosure (dims c. 11m N-S; c. 3m E-W) with an entrance (Wth 0.25m) in the W wall indicated by two stones set across the defining feature c 0.25m apart. They probably represent post-medieval house sites and yards, and were first identified and recorded by Gary Dempsey. Compiled by: Michael Moore Date of upload; 23 May, 2016
