On high ground under pasture near the NW end of a steep ridge with commanding views over the lower ground and Galway Bay from WNW to NE. Hachured on the 1842 and 1915 eds. of the OS 6-inch maps. Listed as ‘Enclosure’ in the SMR (1992) and the RMP (1996). A poorly preserved subcircular cashel (int. dims. 23.7m E–W; 21m N–S) enclosed by a broad bank (Wth 3.8–5m; ext. H 1–1.2m at N) with occasionally visible inner and outer facing-stones (max. H 0.2m). It is overgrown from E to S and the bank has been levelled to the S. There is no visible trace of an entrance and a modern field wall runs on the bank from S to NW. There is an unusual density of ringforts in this part of the Burren. Borlase (1897, 65) counted 20 between Derreen West and Derreen East and 33 on the slope on which they occur (including the NW-facing slope of Knockauns Mountain). Westropp (1901, 10–11) reported several of these to be largely levelled and rebuilt as sheepfolds but still believed them to be of ancient origin.

On a short flat stretch near the NW base of a steep ridge with good commanding view NW–NNE. Hachured on the 1842 ed. of the OS 6-inch map and indicated with two solid lines on the 1915 ed. Listed as ‘Enclosure’ in the SMR (1992) and the RMP (1996). A poorly preserved subrectangular cashel (int. dims. 23m N–S; 21.5m E–W) defined by a broad externally faced bank of stone (H 0.5–1m; av. Wth 4m; H 0.5–1m). There is no trace of an original entrance and the interior is generally level and featureless. Later walls are built on parts and the perimeter is overgrown with brambles. There is an unusual density of ringforts in this part of the Burren. Borlase (1897, 65) counted 20 between Derreen West and East and 33 on the slope on which they occur (including the NW-facing slope of Knockauns Mountain).

On a flat-terraced area with further rising terraces to the S and good views from W to E. Hachured on the 1842 and 1915 eds. of the 6-inch OS maps. Listed as ‘Enclosure’ in the SMR (1992) and the RMP (1996). A largely overgrown oval cashel (int. dims. 33m N–S; 30m E–W) defined by a stony bank (Wth 4.4m; ext. H 1.1m; int. H 0.5m) with occasional facing-stones (max. H 0.5m) from N to E. The interior is highest ENE to E and a circular hut foundation (CL004-003002-) occurs W of centre. Two other cashels occur 60m NE (CL004-004----) and c. 180m ENE (CL004-007----). The field walls running between these form a field system (CL004-098----) likely contemporary and potentially partially predating these cashels. There is an unusual density of ringforts in this part of the Burren. Borlase (1897, 65) counted 20 between Derreen West and East and 33 on the slope on which they occur (including the NW-facing slope of Knockauns Mountain).

On a flat terraced area with further rising terraces to the S and good views from W–E. Hachured on the 1842 of the 6-inch OS maps and indicated with a solid line on the 1915 eds. Listed as ‘Enclosure’ in the SMR (1992) and the RMP (1996). A largely overgrown subcircular cashel (ext. dims. 36.3m N–S; 38.8m E–W) defined by a stony bank (Wth 2–12.5m; orig. wall T 2m; ext. H 0.4–0.8m; int. H 0.2–0.5m) with occasionally surviving inner facing-stone (H 0.2m) and outer facing-stones surviving around most of its circumference (H 0.4–0.8m). There is no trace of an original entrance and the interior is generally flat. There is a small circular walled outline near edge in the NNW sector, but at the time of inspection (1997) it was too overgrown to access. A more recent field wall is built on the outer edge of the cashel wall in most sectors. Two other cashels lie 60m SW (CL004-003----) and c. 120m ESE (CL004-007----) respectively. The field walls extending between these form part of a field system (CL004-098----) likely contemporary and potentially partially predating these cashels. There is an unusual density of ringforts in this part of the Burren. Borlase (1897, 65) counted twenty between Derreen West and Derreen East and thirty-three on the slope on which they occur (including the NW-facing slope of Knockauns Mountain). Westropp (1901, 10–11) reported several of these to be largely levelled and rebuilt as sheep folds but still believed them to be of ancient origin.

On a flat rocky terrace with commanding views from NW–E and overlooked by higher ground to the S. Hachured on the 1842 and 1915 eds. of the OS 6-inch maps. Listed as ‘Enclosure’ in the SMR (1992) and the RMP (1996). An oval cashel (25m N–S; 18.5m E–W) defined by a stone wall (orig. T 1.6m). The inner facing survives best in the N half (H 1.6m). The outer facing survives best to the W (H 0.5m). A cattle gap to the SE may also be the site of the original entrance. Other cashels lie c. 180m WSW (CL004-003----), c. 120m WNW (CL004-007----) and c. 130m SW (CL004-103---- and CL004-104----). The field walls running between these form part of a system (CL004-098---- ) likely contemporary and potentially partially predating these cashels. There is an unusual density of ringforts in this part of the Burren. In 1897, Borlase (1897, 65) counted twenty between Derreen West and East and thirty-three on the slope on which they occur (including the NW-facing slope of Knockauns Mountain).

On rough grazing with extensive views to the W–NNE. Hachured on the 1842 and 1915 eds. of the OS 6-inch maps. Listed as ‘Enclosure’ in the SMR (1992) and the RMP (1996). A poorly preserved circular cashel (int. diam. 17.5m) defined by a low grassed over stony bank (Wth 1.5–2m; max. H 0.42m). There is no trace of an entrance and the interior is generally flat and featureless. Low banks that run SE from the ENE and W from the SW may be a remnant of a contemporary field system. A relatively modern square enclosure defined by a drystone wall is located c. 10m to the W and an enclosed doline is located c. 25m to the N. There is an unusual density of ringforts in this part of the Burren. In 1897, Borlase (1897, 65) counted twenty between Derreen West and East and thirty-three on the slope of which they occur (including the NW facing slope of Knockauns Mountain).

A roughly circular cashel (int. diam. 20m) enclosed by a stony bank (Wth 2m; int. H 0.1–0.15m) with external facing-stones surviving highest from NE–S (H 0.8–1.2m). There is no clear trace of an entrance and the interior is generally flat and featureless.

Listed as 'Rectangular enclosure' in the SMR (1992) and the RMP (1996). A rectangular cashel (int. dims. 38m N–S; 30m E–W) defined by a stone wall with outer facing-stones surviving highest (H 1.9m) on its E side. No original inner facing-stones survive and the wall width (Wth 1.25m) is only discernible at the entrance. The entrance is located midway along the S wall and is flanked by two orthostats (H 1.15m and 1.52m). A small hut site (CL004-013003-) is located in the NE corner and an irregular stone spread (H 0.8m) in the SW may mark the site of a second. Another collection of stones (Wth 1.5m; H 0.8m) abutting the inner side of the wall adjacent the E side of the entrance may also mark a feature. A circular cashel (CL004-013001-) lies c. 15m to the W. There is an unusual density of ringforts in this part of the Burren.

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.
