- 15 Dec 2025, Mayo County Council 2560928: Conditional. Permission. EirGrid PLC, with the consent and approval of the Electricity Supply Board (ESB), intends to apply for permission for works to uprate the existing Castlebar - Dalton 110 kV overhead line (OHL). The proposed development will take place within the following townlands: Liscromwell Carrowkeel Brees Breandrum or Windsor Prison South Facefield Aghalusky Drumnaslooeen Mossbrook Cloontybaunan Ballinagran Ballynastangford Lower Derrynamraher Rathredmond Birchfield Cappavicar South Dooros Garrywadreen Keelkill Drumadoon Drumneen Ballinvoash Legaun Ballynastangford Upper Gneeve Ballymacloughlin Drumneen (Prendergast) Lisnaran Ballyrourke Ballynew Drumcorrabaun Pollavaddy Eskerlevally Kilmacrade Moat Drumneen South Burris Garhawnagh Castlegar Barrackland Carrowgarve Crantahar Rinnahulty Knocknamoghalaun Drumkeen Carrowmore Rathduff Clare Derreen Heathlawn Kilbeg-Malone Prison North Coolaghbaun The Castlebar - Dalton 110 kV circuit is 27.8 km in length and runs between the existing Castlebar 110 kV substation in the townland of Aghalusky in central County Mayo, to Dalton 110 kV substation located in the townland of Clare, eastern County Mayo. The OHL has a total of 144no. supporting structures. The proposed development will comprise: ? the replacement (“restringing”) of the existing OHL circuit conductor wires with a new higher capacity conductor between Castlebar 110 kV and the Dalton 110 kV substations; ? the replacement of end mast in-situ at 1no. location, with a similar structure; ? the replacement of angle masts in-situ at 6no. locations, with similar structures; ? the strengthening of tower foundations at 4no. locations; ? the strengthening of towers (i.e., member replacement) at 10no. locations; ? the painting of towers at 10no. locations; ? the replacement of tower bolts at 3no. locations; ? the replacement of polesets at 48no. locations, with similar structures. The change in structures will result in standardised heights from 16 m to 24 m along the circuit. The majority of the height increases will be between 0.1 m and 2.0 m; ? the replacement of insulating and ancillary hardware at all structure locations; ? the replacement of earthwire between structure number 132 and structure number 144; ? the replacement of stay wire / anchors and associated fittings at 16no. locations; ? the replacement of crossarms at 58no. locations; ? all associated temporary site development works to gain access to the existing structures inclu.

- 9 Oct 2025, Mayo County Council 2560709: Conditional. Permission. EirGrid PLC, with the consent and approval of the Electricity Supply Board (ESB), intends to apply for permission for works to uprate the existing Cashla - Dalton 110 kV overhead line (OHL). Within County Mayo, the proposed development will take place within the following townlands: DALGAN DEMESNE, POLLBAUN, CARROWBEG WEST, GORTEENS, SEEFIN, BROOKHILL, CARROWMORE, BALLYHANKEEN, RUSHBROOK EAST, BALLYCUSHEEN, SCARDAUN WEST, MILLBROOK, MILFORD DEMESNE, CURRAGHADOOEY, LISDUFF, RATHGRANAGHER (MILLER), DRUMMIN WEST, CARROWBEG EAST, RATHGRANAGHER (LINDSAY), CROSSBOYNE, KILBEG-MALONE, DAVROS, DERRY, CLARE, GREAGHANS, COOLROE, ROOS, LEEDAUN The Cashla - Dalton 110 kV OHL circuit runs through County Galway and County Mayo. It is 57.7 km in length and travels from Cashla 110 kV substation in Barrettspark in central County Galway and traverses northwest to the Dalton 110 kV substation (County Mayo). The OHL has a total of 271no. supporting structures. Within the functional area of Mayo County Council, there is 24.7 km of the existing OHL circuit, with 111no. structures. Within the functional area of Galway County Council there is 33.0 km, with 160no. structures. Separate planning applications will be lodged with Galway County Council. The proposed development within Co. Mayo will comprise: • the replacement (“restringing”) of the existing OHL circuit conductor wires with a new higher capacity conductor between structure no. 160 and Dalton 110 kV substation; • the replacement of angle masts in-situ at 6no. locations, with similar structures; • the strengthening of tower foundations at 2no. locations; • the strengthening of towers (i.e., member replacement) at 6no. locations; • the painting of towers at 7no. locations; • shear block remedial works of a tower at 1no. location; • the replacement of polesets at 83no. locations, with similar structures. The change in structures will result in standardised heights from 16 m to 23 m along the circuit. The majority of the height increases will be between 0.1 m and 2.0 m (at 70no. structures), with 12no. structure replacements resulting in no change in height. Structure no. 263 will increase in height by 7.0m; • the replacement of insulating and ancillary hardware at all structures from structure no. 161 to 271; • the replacement of earthwire between structure no. 261 and structure no. 271; • the replacement of stay wire / anchors and associated fittings at 7no. locations; • the replacement of crossarms at 7.

- MA111-057: Barrow - pond barrow, https://heritagedata.maps.arcgis.com/apps/webappviewer/index.html?id=0c9eb9575b544081b0d296436d8f60f8&query=18a4b61b268-layer-9%2CSMRS%2CMA111-057----. In improved pasture, on level elevated ground, with a slight slope down to S. Good views. Circular sunken area (25m E-W, 24.5m N−S, crest of bank) defined by a broad, substantial earthen bank. The bank is quite compact, rounded on top with a broadly sloping external slope (Wth slope 5m at N, 8m at S; ext. H 0.85m at N, 1.6m at S). The inner slope of the bank merges seamlessly in a broad steep slope (Wth slope c. 10m; int. H 1.55m) with the interior, giving an overall saucer-shaped profile. However, the interior does not appear to be significantly lower than exterior ground level, except on the S side.. A scatter of stones is evident along the top and inner slope of the bank, and few stones are also scattered in the base of the interior, which is soft and wettish underfoot in the centre. There is a low section of bank at SE but it is unclear if this is an entrance. A field wall, coinciding with the townland boundary, crosses the enclosure on a NNE−SSW axis slightly E of centre. Hawthorn, ash and sycamore trees grow on the field wall. Hawthorn and gorse ring the enclosing bank. Compiled by: Jane O'Shaughnessy Date of upload: 21 December 2022

In gently undulating grazing land; views good but not extensive. Shown on the 1838 and 1915 OS 6-inch maps as a circular enclosure (diam. 30-35m) incorporated into later field boundaries on the N arc with a farmstead immediately to NW. The enclosure has been subsumed into a rectangular orchard dotted with apple trees and a few elder bushes. The orchard is enclosed on E, S and W by straight field walls, and is bordered on the N side by a row of three farm sheds. Mature conifers grow all around the perimeter of the orchard, just inside the line of the enclosing wall. The enclosed space (34.4m ENE−WSW; 23.3m NNW−SSE) is level and appears to be slightly raised relative to exterior ground level –this is most noticeable on the W half where the ephemeral outline of a curving rise –possibly a levelled bank- can still be traced.

A townland is the smallest land division of Ireland, and the unit of a rural address; old registers such as the 1901 and 1911 censuses file it under its civil parish and barony.

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.
