Recorded monuments

• MO012-050 Crannog
  Description

  Located in Roosky Lough, which is a rectangular lake (max. dims c. 370m WNW-ESE; c. 160m NNE-SSW) with a rectangular extension (max. dims c. 350m NNE-SSW; c. 110m WNW-ESE) extending S from its W end. It is suggested that there are three crannogs in the lake (Smyth 1954, 5), and this might be the third. The lake is greatly reduced from its representation on the 1834 edition of the OS 6-inch map, but this feature, depicted as the bulbous end of a promontory (dims c. 25m NE-SW; c. 15m NW-SE) on the 1907 OS 6-inch map appears to be a natural feature. The above description is derived from the published 'Archaeological Inventory of County Monaghan' (Dublin: Stationery Office, 1986). In certain instances the entries have been revised and updated in the light of recent research. Revised by: Michael Moore Date of revision: 17 July 2007

• MO012-051 Crannog
  Description

  Located in Roosky Lough, which is a rectangular lake (max. dims c. 370m WNW-ESE; c. 160m NNE-SSW) with a rectangular extension (max. dims c. 350m NNE-SSW; c. 110m WNW-ESE) extending S from its W end. Two crannogs in an L-shaped lake are represented on a Bartlett map of 1602-03, which have been mistaken for the crannog in Monaghan town (MO009-037----) (O’Sullivan 1997, Pl. 58), but the representation corresponds closest to Roosky lake (pers. comm. Grace Moloney 2012). The Bartlett map indicates that these crannogs were occupied or re-occupied in the sixteenth and seventeenth centuries when Roosky was a power centre of the Dartry Mac Manons (Ó Mórdha 1957, 156-8). The lake is greatly reduced now from its representation on the 1834 edition of the OS 6-inch map. This W crannog is a circular island (diam. 14m N-S; 13m E-W; H 0.7m over the water) surrounded by reeds, except at S where the water is deep. The matrix is stones and clay, but piles can be seen protruding from the mound at S. The above description is derived from the published 'Archaeological Inventory of County Monaghan' (Dublin: Stationery Office, 1986). In certain instances the entries have been revised and updated in the light of recent research. Revised by: Michael Moore See the attached image from Bartlett's map with this crannog at right centre.

• MO012-052 Crannog
  Description

  Located at the E end of Roosky Lough, which is a rectangular lake (max. dims c. 370m WNW-ESE; c. 160m NNE-SSW) with a rectangular extension (max. dims c. 350m NNE-SSW; c. 110m WNW-ESE) extending S from its W end. Two crannogs in an L-shaped lake are represented on a Bartlett map of 1602-03, which have been mistaken for the crannog in Monaghan town (MO009-037----) (O’Sullivan 1997, Pl. 58), but the representation corresponds closest to Roosky lake (pers. com. Grace Moloney 2012). The Bartlett map indicates that these crannogs were occupied or re-occupied in the sixteenth and seventeenth centuries, when Roosky was a power centre of the Dartry Mac Mahons (Ó Mórdha 1958, 156-8), and probably had been over the previous centuries. The lake is greatly reduced now from its representation on the 1834 edition of the OS 6-inch map. This E crannog is a circular overgrown island (diam. 18m; H 1m over the water) with deep water c. 2-3m from its shore. Erosion on the N side reveals a matrix of stones with some piles (diam. 0.1-0.2m) spaced c. 1-1.5m apart. The possible ringwork castle (MO012-054----) is on the shore just to the E. The above description is derived from the published 'Archaeological Inventory of County Monaghan' (Dublin: Stationery Office, 1986). In certain instances the entries have been revised and updated in the light of recent research. Revised by: Michael Moore See the attached view of Bartlett's map with this crannog in the right foreground. Date of revision: 29 January 2018

• MO012-053 Castle - ringwork
  Description

  Situated on a low N-S spur at the E end of the N arm of Roosky Lough (max. dims c. 370m WNW-ESE; c. 160m NNE-SSW), with a small N-S stream forming the E and S edges and with the crannog (MO012-052----) just 50m offshore to the W. Roosky was a power centre of the Dartry McMahons, and Brian Mac Aodha Óg Mac Mahon, the last elected chief of the Mac Mahons who died in 1622 made it his base (Smythe 1954, 5). He was said to have ‘a faire new House’ there to which he retired after 1614 (Ó Mórdha 1957, 155-9), and this may be what was called the castle. This location is described only on the 1907 edition of the OS 6-inch map as the ‘site of Roosky Castle’. Ruskill (Roosky (6)) is indicated in Killkeevan parish on the Down Survey (1656-8) barony map of Dartry, for which see this web-page accessed on 20/04/2016 http://downsurvey.tcd.ie/down-survey but no structure is indicated. In the local folk tradition (IFC 951, 326: https://www.duchas.ie/en/cbes) it was known to be a McMahon castle. A grass-covered fosse (Wth of top 12m; Wth of base 4m; int. D 1.4m; ext. D c. 1.2m) WNW-N-NE and curving out to the N separates the promontory from the land to the N creating an oval, grass-covered enclosure (dims 65m NNW-SSE; 30m WSW-ENE) with scarped sides at W and E (H c. 1.8-2.4m). There are no internal structures visible or any evidence of a causeway across the fosse. The above description is derived from the published 'Archaeological Inventory of County Monaghan' (Dublin: Stationery Office, 1986). In certain instances the entries have been revised and updated in the light of recent research. Compiled by: Michael Moore Date of revision: 29 January, 2018
