Situated on an E-W orientated ridge on a slight NE-facing slope. Views are excellent in all directions. Circular area (diam. 20m) enclosed by a bank of rubble limestone (Wth 1.5-4m; int. H 0.6-0.9m; ext. H 0.6m). No fosse visible. The bank encloses the site SE-NE; the external face has been rebuilt as a field wall SE-W and a field wall has been built on top of the bank W-NE. A NNW-SSE orientated drystone field wall crosses the site intersecting with the cashel bank at NE and at SE. To the E of this wall the bank is absent and the line of the bank is defined by a very slight scarped edge. Original entrance not recognisable. Compiled by: Patrick F.

Situated on a slight N-facing slope in gently undulating pasture. Slightly raised circular area (diam. 32m) enclosed by an un-coursed rubble limestone wall (T 0.8m; H 1.5m). The wall appears to have been reconstructed in recent times and encloses the site E-SW with only the footings of the cashel wall surviving SW-E. Original entrance not recognisable.

Situated at the base of slight hollow on slight SW-facing slope in gently undulating pasture. Roughly circular area (diam. 33m) enclosed by a collapsed wall (T 3.1m; H 1m) of limestone rubble. No fosse visible. Either of the breaks in the wall at W (Wth 3m) or at E (Wth 2.8m) may mark the position of the original entrance. Compiled by: Patrick F. O'Donovan Date of upload: 21 April 2011

Situated on a slight rise in gently undulating pasture. Circular area (diam. 29m) defined by a rubble limestone wall (int. H 1.45m; ext. H 1.5m; T 2.6m). No fosse visible. The wall is made up of un-coursed limestone rubble and encloses the site E-NE. From NE-E the wall has been removed down to the footings. The internal face of the wall has been re-built E-NE to form a drystone field wall (T 0.6m; int. H 1.45m; ext. H over top of cashel wall 0.2m) but the original large basal blocks survive. The original external facing of un-coursed blocks survives E-NE. An E-W orientated field wall links to the external face of the cashel wall at WNW and a NW-SE orientated field wall abut the external side of the wall footings NE-ENE. Original entrance not recognisable. The remains of a souterrain (SL005-065002-) are located in the centre of the interior. Compiled by: Patrick F. O'Donovan Date of upload: 21 April 2011

Located within the interior of Derrylehan cashel (SL005-065001-). An oval rock filled depression (dims. 6m NW-SE; 4m NE-SW; D 0.4m) appears to be an in-filled souterrain entrance.

Situated in slight broad hollow, on a slight E-facing slope, in gently undulating pasture. Views are poor in all directions. Roughly circular area (diam. 20m) enclosed by a modern drystone wall (T 1.5m; H 1.1m). There is no fosse visible at ground level. A drystone field wall defines the enclosure SW-NE following the line of the original enclosing element. From NE-SE the limit of the enclosure is defined by a N-S orientated drystone field wall. From SE-SW the limit of the enclosure is defined by an E-W orientated drystone field wall. A ruined post-medieval house straddles the line of the enclosing element at SE. The original entrance is not recognisable. Compiled by: Patrick F. O'Donovan Date of upload: 21 April 2011

In gently undulating terrain. Not marked on the 1837 edition of the OS 6-inch map. Recorded in 1991 as a circular structure (dims. 3m x 2.8m) built of mortared stone (SMR (1989) file). It was built into the slope of a naturally-occurring rise(H at bottom of slope 2m; H at top of slope 0.7m) there was a circular opening (diam. 1.5m) on top and an opening (Wth. 0.7m; H 0.9m) in the N face which gave access to the central opening (SMR (1989) file). The site is now located at NNW edge of a c.10 year old coniferous plantation and is inaccessible. Compiled by: Patrick F. O'Donovan Date of upload: 21 April 2011
- SL005-196: Burnt mound, https://heritagedata.maps.arcgis.com/apps/webappviewer/index.html?id=0c9eb9575b544081b0d296436d8f60f8&query=18a4b61b268-layer-9%2CSMRS%2CSL005-196----. In pasture, located on a slight N–facing slope, at the interface between gently rising dry ground to SE and a flat expanse of rush-grown damp ground which extends to NW. A very low, barely discernible subcircular grass-covered rise (11-12m E–W; c. 12m N–S; H 0.3m at N) composed of black, charcoal-rich soil and angular stone fragments. The mound appears to have been partly levelled in the past; the N arc can be clearly traced, as it is enhanced by a slight natural fall of ground, but at SE–S the mound grades seamlessly into the surrounding ground, and its exact limits are uncertain. A fulacht fia (SL005-197----) and a possible burnt mound (SL005-198----) are located 120m and 140m to SW, respectively. There is a church (SL005-061001-) and graveyard (SL005-061002-) 50m upslope to SSE. Compiled by: Jane O’Shaughnessy Date of upload: 28 May 2019
- SL005-197: Fulacht fia, https://heritagedata.maps.arcgis.com/apps/webappviewer/index.html?id=0c9eb9575b544081b0d296436d8f60f8&query=18a4b61b268-layer-9%2CSMRS%2CSL005-197----. Located on the S margins of an expanse of damp, rush-grown boggy pasture, on the W bank of a small, shallow N-flowing stream. The stream rises 6m to SE of the fulacht fia, at the interface of the wet ground with gently rising drier ground. This fulacht fia is evident as a low, roughly crescent-shaped, grass-covered mound (c. 9m NW–SE; c. 4m NE–SW; H 0.3m) composed of a concentration of angular stone fragments in black, charcoal-rich soil. The mound may have been disturbed in the past, and its exact original extent is uncertain. A slight boggy depression on the E side, intervening between the mound and the stream probably marks the trough area. There is a possible burnt mound (SL005-198----) 15m to SW, and a burnt mound (SL005-196----) 120m to NE. A church (SL005-061001-) and graveyard (SL005-061002-) are located 125m to ENE.

- SL005-198: Burnt mound, https://heritagedata.maps.arcgis.com/apps/webappviewer/index.html?id=0c9eb9575b544081b0d296436d8f60f8&query=18a4b61b268-layer-9%2CSMRS%2CSL005-198----. In pasture, located at the interface between gently elevated drier pasture to S and flat expanse of rush-grown damp ground which extends to N. A spring/small stream, beside which there is a fulacht fia (SL005-197----), rises 15m to NNE. This possible burnt mound is evident as a very low, moss- and grass-covered rise (c. 7-8m E–W; c. 5m N–S; H 0.2-0.3m, 0.4m at N), which appears to be composed of angular stone fragments in black soil. It is poorly defined, distinguished mainly by differential vegetation growth. There is a burnt mound (SL005-196----) 120m to NE. A church (SL005-061001-) and graveyard (SL005-061002-) are located 140m to NE. Notified to NMS by Leo Leydon. Compiled by: Jane O’Shaughnessy Date of upload: 28 May 2019

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.
