• MO020-018 House - fortified house
  Description

  Located on a shelf towards the bottom of a NE-facing slope which overlooks White Island and the N end of Muckno Lough. Sir Edward Blayney was a captain in the English garrison at Monaghan town (MO009-060----) from 1602. He was instrumental in establishing its defences and in the building of a fortified house (MO009-060003-) there, for which he received a grant of former church land in Monaghan barony. In 1607 he received a grant of land at Ballylurgan, also known as Ballifort, which consisted of two ballybetaghs (or villages, each of sixteen tates or townlands) in Cremorne barony on condition that he built a fort there within four years (Lavery 1907, 31-2). The location was half-way between Monaghan town and Newry, and the castle would provide a secure halting-place in re-supplying the former from the latter (Livingstone 1966, 141-2). In 1612 Sir Edward received a further grant of the Muckno church lands, which included the ballybetaghs of Ballinknockluske (Coyle 1980), with the result that he could have held seven of the twenty two ballybetaghs in Cremorne barony. In 1621 Sir Edward was elevated to the peerage as the first Lord Blayney. A contemporary description describes the house as: 'Sr. Edward Blanye hath buylte a very large bawn w'th lyme and stone 18 foote high, well flanked w'th bulworkes upon his land of Ballinelungan… Upon the bawne is buylte a fayre gate house and two other houses of lyme and stone upon two of the corners of the bawn w'ch flankes the whole work. They containe two or three roomes or lodginges a pice w'th chimneys; In w'ch Bawne he is buyldinge a fayre and spacious house of stone worke already two yards high above the grounde, the walles of a great thickness w'th vaults all buylte upon his own charge' (Shirley 1879, 241; Hunter 1975 81-2). In 1642 the castle was occupied by rebels led by several of the local MacMahons who despoiled the estate and may have destroyed the castle irreparably as there is very little record of it thereafter. Between 1648 and 1653 Edward, the third Lord Blayney, sold all the property to Thomas Vincent, a London merchant. Shortly afterwards Vincent’s daughter Elizabeth married Richard, the brother and heir of Edward, and brought the Cremorne land back in her dowry to the Blayney family, but her father disposed of the land in Monaghan barony separately (Shirley 1879, 247). This may have restored the family fortunes for a while but the estate was always in difficulty and it seems that the castle might never have been restored. By the end of the eighteenth century the castle was certainly a ruin, and a drawing by Francis Grose made in 1770 shows that it was T-shaped, of two storeys and attic with corner machicolations supported on continuous corbels in the Scottish fashion (Grose 1791, vol. 2, 72, Pl A, B). The castle was replaced with the present house, known as Castleblayney Castle, which was built in 1799 to a design of Robert Woodgate. The estate was sold by the twelfth and last Lord Balyney in 1853 to Henry Thomas Hope of Deepdene, Surrey, and the house is known as Hope Castle ever since. The location of the old castle is not known with absolute certainty, but Coote (1801, 91) says the new house was built contiguous to the old castle. 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.

• MO020-018001 Bawn
  Description

  Located on a shelf towards the bottom of a NE-facing slope which overlooks White Island and the N end of Muckno Lough. Sir Edward Blayney built a fortified house (MO020-018----) after 1612 on land he had been granted in Cremonrne barony at Ballylurgan, also known as Ballifort. A contemporary description describes how he ‘hath buylte a very large bawn w'th lyme and stone 18 foote high, well flanked w'th bulworkes upon his land of Ballinelungan… Upon the bawne is buylte a fayre gate house and two other houses of lyme and stone upon two of the corners of the bawn w'ch flankes the whole work. They containe two or three roomes or lodginges a pice w'th chimneys;’ Inside the bawn he buit a ‘fayre and spacious house’ (Shirley 1879, 241; Hunter 1975 81-2). The precise location of the house and bawn is not known, but Coote (1801, 91) says the new house which was built in 1799 was contiguous to the old one.

• MO020-019 Enclosure
  Description

  Located towards the SE end of a NW-SE drumlin ridge overlooking the N end of Muckno Lough and on the old demesne land of Blayney Castle. It is represented as a hachured feature only on the 1907 edition of the OS 6-inch map. This is a subcircular grass-covered area (dims 26m ENE-WSW; 21m NNW-SSE) with some mature deciduous trees on the bank. It is defined by a fosse (at SW: Wth of top 2.9m; Wth of base 1.3m; int. D 0.3m; ext. D 0.55m) and an outer earthen bank (at SW: Wth of base 5m; Wth of top 2.1m; ext. H 1.9m) that is removed N-NE. There are entrance gaps in the bank at SSE (Wth of base 2m) and NNW (Wth of base 1.9m). 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: 22 June 2018

• MO020-027 Church
  Description

  Located on a shelf that slopes down gently to the N with slightly lower ground to the W before a hill rises over the town of Castleblayney, but the ground falls away steeply to the N and E. The parochial centre of Muckno parish moved from what was the site of St Maodóid’s monastery and the medieval parish church at Church Hill (MO020-020001-), on the E shore of Lough Muckno, to Castleblayney during the seventeenth century. The last will of Edward, the first Lord Blayney who died in 1629, directed that his body was ‘to be buried in the church of Castle-Blayney’ (Lodge and Archdall 1789, 308). It is not clear if there was a church at this location then as he was buried in Monaghan Church (MO009-060012-) (ibid, 309). The first church of Castleblayney appears to have been built in the last quarter of the 17th century by William, the sixth Lord Blayney who was born in 1671 at Castle Blaney (MO020-018----). He died in 1706 and was buried in the graveyard of the chapel of Castle-Blayney (ibid., 317). This is a rectangular structure (int. dims 20.2m E-W; 7.3m N-S) with a contemporary porch (int. Wth 2.35m; L 3.4m) located towards the W end of the S wall. The walls (Wth 0.8m; H 0.9-1.2m) of the church survive with soil built up externally but the interior of the church is open to the original level and has graves dating from 1859. The NE and SE angles have external buttresses supporting them, and the mausoleum of Thomas Andrew, the eleventh Lord Blayney, is inserted into the E end of the church, which is at the N end of a subrectangular graveyard (dims c. 170m NNW-SSE; c. 60m ENE-WSW) defined by masonry walls. A new church was built at the centre of the graveyard in 1810 (Lewis 1837 vol. 2, 408), and this was replaced on the same site by the present church of St Maeldoid in 1858-60 to a design of Joseph Welland, and this church still prospers.

• MO020-027001 Graveyard
  Description

  Located on a shelf that slopes down gently to the N with slightly lower ground to the W before a hill rises over the town of Castleblayney, but the ground falls away steeply to the N and E. The parochial centre of Muckno parish moved from the site of St Maodóid’s monastery and the medieval parish church at Church Hill (MO020-020001-), on the E shore of Lough Muckno, to Castleblayney during the seventeenth century. William, the sixth Lord Blayney probably built the church (MO020-027----) at the N end of a subrectangular graveyard (dims c. 170m NNW-SSE; c. 60m ENE-WSW) defined by masonry walls. The oldest memorials dating from c. 1770 are around this structure on a slightly rising area (diam. c. 45m), forming the original graveyard. The present Church of Ireland church of St Maeldoid which was built in 1858-60 is a replacement for a church on the same site at the centre of the graveyard that was built in 1810 (Lewis 1837 vol. 2, 408) Compiled by: Caimin O'Brien Revised by: Michael Moore Date of revised upload: 22 June 2017
