• WM033-031 Church
  Description

  In N quadrant of graveyard (WM033-031001-). Ivy-covered rectangular church (ext. dims. 20.8m E-W; 7.55m N-S; int. dims. 14.8m E-W; 6.3m N-S; wall T 0.9m) with two storey priests residence or vicarage at W end of church. The walls are covered in ivy and the interior of the church is covered with trees and bushes making detailed examination of the building impossible. The walls of the church where visible are built with large random rubble, most of the walls survive to full height except a section of the W end of the N wall where it joins onto the priest’s residence. At this junction the first floor section of the NE corner of the priest’s residence has also collapsed. The church was entered through a doorway now visible as a broken out gap located off centre to the W in the S wall. The original dressed stone medieval doorway was taken from this church and reused as the front door into Meedin R.C. church (WM033-040----) located 3km to the SW. A medieval twin light transom and mullioned window was also taken from this church and inserted into the N gable of Meedin R.C. church (WM033-040001-). A single light window can be seen in the centre of the N wall. A single light ogee headed window with glazing groove is located off centre to the E in the S wall. This window is set into a widely splayed segmental-arched embrasure with punch dressed jamb stones. There is good evidence of internal render on the S wall of the church and on the punch dressed jambs of the window embrasure. A second single light ogee-headed window now covered in ivy is located in the centre of the S wall. A small square-headed wall press (dims. H 0.3m x Wth 0.43m; D 0.42m) or aumbry is located at the E end of the S wall close to the SE corner of the church. The E window which is no longer in situ sits in a widely splayed embrasure that is now covered in ivy making detailed examination impossible. An earlier site report from 1977 described the E window as standing inside a round-headed embrasure with an arch of dressed stones, three of which are decorated with carvings in relief (SMR File). Two of the decorated stones were located on the N side of the window embrasure. One of these stones has the outline of a rectangle which is quartered by a central cross with a saltire cross in each of the four quadrants. The stone below it is decorated with a double ribbon interlace pattern with spear-shaped terminals. The third stone was located on the S side of the window was decorated with a carved head wearing a possible mitre of a bishop lying horizontally on the stone. This stone also contains the carving of a four-legged mythical animal with a human head claw-like feet and tail which curves underneath the body and runs between its legs and then returns up and above the body of the animal terminating in a fleur-de-lys pattern. These decorated stones are no longer visible due to the dense cover of ivy. The carvings are very similar to the carvings on the twin light window taken from this church and inserted into the N gable of Meedin R. C. church. The twin light transom and mullioned window (WM033-040001-) was probably the E window of the medieval church at Castlelost as there is no evidence today of an in situ E window. The ground floor (int. dims. 6.3m N-S; 3.25m E-W; wall T 1-1.2m) of the priests residence located at the W end of the church was entered from the body of the church through a round-headed doorway (Wth 0.96m) located in the centre of the E wall of the priests residence. The round-headed doorway is constructed with roughly shaped voussoirs with triangular shaped keystone in a similar fashion to doorway at Castlelost Castle (WM033-043----). A drawbar slot can be seen on the S side of the doorway embrasure. The ground floor of this residence was covered with a pointed stone vault (H 2.6-3m) with evidence of wicker centring on the underside of the vault. A single light square-headed window in the centre of the S wall provided light to the vaulted chamber. A section of the stone vault has collapsed above this window. There was no feature or window opening in the W or N walls of the residence at ground floor level. There are no visible signs of any access from the vaulted ground floor to the first floor except for the hole in the vault that appears to be recent collapse rather than an original opening for a wooden stairs. Access to the first floor appears to have been from an external stairs no longer visible in the NE angle of the church. The section of the church wall no longer survives. At first floor level there are the remains of a single light window in the N wall with large opening in the NE angle where an external stairs now collapsed gave access to the first floor. In the centre of the E wall are the ivy-covered remains of a single light window, and a single light square-headed window in the centre of the S wall. A broken out fireplace (Wth 1.2m; D 0.6m) is located off centre to the N in the W wall with a single light window (int. Wth 1m; ext. Wth 0.3m) to the S and square-headed wall press (dims. H 0.5mx Wth 0.5m x D 0.4m) in the SW angle. The medieval church of Castlelost was listed in the 1306 ecclesiastical taxation of the Diocese of Meath where it was valued at 5 marks per annum with a tenth value of ½ mark (Cal. doc. Ire., vol. 5, 258). In 1486, Maurice Tirrell [Tyrrell] of Fertullagh, lord of Castleofty [Castlelost], granted to Walter, abbot of St Mary's Abbey, Dublin the advowson of the parish church of Castlelofty [Castlelost] (Gilbert 1884, 18).

• WM033-031001 Graveyard
  Description

  This monument was inspected in 1977 and described as a sub-rectangular shaped graveyard (dims. c. 57m N-S; 52m E-W) enclosed by a fairly modern stone wall. The graveyard is entered through a gateway in the S wall of the graveyard. The remains of a medieval church (WM033-031----) stand in the NE quadrant of the graveyard. There are a small number of memorials visible to the S of the church some of which are 18th century in date and also some fragments of dressed stone taken from the church have been set into the graveyard possibly as burial markers. No burials are visible to the W, N and E of the church. Compiled by: Caimin O'Brien Date of upload: 10 July 2013

• WM033-031002 Tomb - effigial
  Description

  I was unable to locate this effigial tomb that was located inside the medieval church (WM033-031----) ruins of Castlelost due to the dense cover of vegetation and trees inside the church. This monument was described in 1826 when it was recorded that the 'antient and ruined church (WM033-031----) contains numerous disregarded and mutilated monuments of this family (Tyrrell), amongst which is conspicuous an altar-tomb, bearing the representation, in alto relieve, of a knight, in complete armour. This monument has suffered so much from the neglect of contumely of successive ages, that the name it was intended to commemorate cannot now be ascertained. From the embellishments it would appear to be of the sixteenth century, and was, probably erected for Sir John Tyrrel, of Castel-Lost, father of James of the same place, whose son, Gerald, or Garret Tyrrel, of Castle-Lost, Esq. died April 6th, 1637, and was here interred. The Castle-Lost estates were forfeited by the Tyrrel family, in the troubles of the seventeenth century’ (Brewer 1826, 252). Compiled by: Caimin O'Brien Date of upload: 23 July 2013.

• WM033-031003 Ecclesiastical enclosure
  Description

• WM033-042 Castle - motte and bailey
  Description

  Situated on top of a natural glacial hillock with good views in all directions. Castle ruins (WM033-043----) located 20m to the E with medieval church (WM033-031----) and graveyard (WM033-031001-) located 400m to the N. This motte and bailey castle consists of a poorly preserved high, steep-sided mound of earth and stone the S side of which has been cut into by the construction of the Rochfortbridge road running NW-SE. A photograph of the monument taken in 1910, shows the motte as a high steep-sided mound (H c. 5m; top diam. 20m x 12m) with rounded summit, giving the mound a typical pudding bowl profile (Orpen 1910, 226). This classic shape and profile of the motte is no longer apparent due to soil erosion and vegetation cover. Traces of a stone structure can be seen on the poorly preserved summit (dims. NW-SE 8m; NE-SW 3.5m) of the motte that appear to be the remains of an Ordnance Survey Trigonometrical Station as depicted on all editions of the OS 6-inch maps. The sides of the motte are defaced in several places and show signs of scarring where the soil has slipped down exposing the core of the mound. The stone castle (WM033-043----) to the E of the motte appears to be standing on the scarp of a raised area which may be the remains of a bailey or courtyard associated with the motte castle. A large hole in the NE quadrant of the bailey located to the N of the castle may be the remains of a levelled building described in 1826 as a mansion-house (Brewer 1826, 252) and is possibly a gatehouse that was built onto the N side of the stone castle and controlled the entrance into the interior of the bailey on this side of the earthwork. This possible bailey area (dims. c. 55m N-S x 41m E-W) was then reused as a courtyard for the stone castle. This Anglo-Norman earth & timber castle may have been constructed by the Anglo-Norman knight, Hugh Tyrel [Tyrrell] between 1186-1223 (Orpen 1906, 227-8). In 1223, King Henry III notified the Archbishop of Dublin, who was then Justiciar of Ireland that he had, ‘taken the homage of Hugh Tyrel for the lands which he holds in capite in that country. Mandate to the justiciary that, having accepted from Hugh security for the relief due out of those lands, he give him seisin thereof’ (Cal. doc. Ire., 168). In 1232 Hugh Tyrel was granted a ‘yearly fair at his manor of Newetown in Fertelagh [Fertullagh]’ (Cal. doc. Ire., 289). The manor of Newtown is located in the parish of Newtown which is the adjoining parish to Castlelost and was probably centred around the present village of Tyrrellspass located 5km to the SSW (Orpen 1910, 227).

• WM033-043 Castle - unclassified
  Description

  On raised hillock with good views in all directions. Castle appears to be standing on the E edge of a bailey belonging to Castlelost motte (WM033-042----) located 20m to the W. Church (WM033-031----) and graveyard (WM033-031001-) located 400m to the N. The defensive earthworks around the castle which had an adjoining building referred to as a ‘mansion house’ were described in 1826 when Brewer stated that at Castlelost are the ‘ruins of a castle, of a mansion-house, and a church (WM033-031----). The castle still exhibits traces of strong outworks, and was protected by a moat (WM033-042----). This castle, and the adjoining mansion, long afforded a residence to the Tyrrel family. The Castle-Lost estates were forfeited by the Tyrrel family, in the troubles of the seventeenth century’ (Brewer 1826, 252). Present remains consist of a rectangular castle (ext. dims. c. 15.5m E-W; 8.8m N-S; wall T 1.6 - 2m) aligned NNE-SSW surviving two storeys high with high stone vault (long axis E-W) over the ground floor. The castle had an adjoining building described in 1826 as a 'mansion house' but now reduced to earthworks with a large depression or hollow which has the appearance of a quarry-hole on the N side of the castle. For purpose of clarity the walls of the castle will be described as N, S, E and W. The walls of the castle have no base batter and are built of random rubble with no cut stone used for the quoins or other architectural features. The castle was entered at ground floor (int. dims. c. 12.3m E-W; 5.2m N-S) through a broken out doorway (Wth 1.3m) located off centre to N in W wall close to the NW angle. The undressed voussoirs of the arch of this doorway can be seen on the N side only, elsewhere they have been robbed out. The remains of a drawbar slot (dims. 0.3m x 0.3m x 1.9m L) can be seen in the S side of the doorway embrasure (Wth 1.6m). The doorway was set into a wide segmental arched embrasure with roughly shaped voussoirs with very crude triangular-shaped keystone. The ground floor chamber was lit by a single slit ope set into a widely splayed segmental-arched embrasure (Wth 1.3m) to S of doorway in W wall and by two slit opes in the S wall. A large broken out gap (Wth 2.2m) at the E end of the S wall close to the SE angle may have been a window originally. No evidence of any window openings in the N wall of the ground floor as there was an adjoing building on this side of the castle. The W end of the ground floor is difficult to examine due to the collapsed debris of the stone vault over this section of the ground floor. A slit ope can be seen off centre to the N in the E wall close to the NE corner. This window appears to have provided light to a mural stairs which gave access to the first floor. The rising scar line of a lintelled mural stairs can be seen in the inner face of the E wall suggesting the stairs rose from the NE angle of the ground floor to the SE angle of the first floor. The remains of a short section of vaulting can be seen in the NE angle of the ground floor suggesting that there was a vaulted lobby area in this angle giving access to the mural stairs. A cross wall may have been located at the E end of this castle which no longer survives due to the collapse of the stone vault at this end of the castle. Above the doorway in the centre of the W wall there is a large gap directly beneath the vault may have been a window embrasure which may suggest that there was a loft or entresol level beneath the vault. There are possible beam holes belonging to a wooden floor of this entresol visible in the S wall, although the robbing out of the wall along this section makes it difficult to be certain. The ground floor was covered by a high roughly pointed stone vault (H 4.65m) that has collapsed at the E end. Only the lower courses of the first floor survives and no architectural features are visible in these walls. A low earth and stone bank (Wth 3m; H 0.2m) can be seen running off the SE angle of the castle may be the remains of the enclosing element of the bailey that was reused as the courtyard of the stone castle. Immediately to the N of the castle are the remains of a series of earthworks and a large depression like a quarry hole which appears to be the grass-covered wall footings of the mansion house described in 1826. This building stands on the NE edge of the scarp of the bailey with a possible entrance gap (Wth 3m) giving access to the interior of the castle courtyard which suggests that this levelled building may have acted as the gatehouse of the castle. No clear pattern or outline of this building can be determined from the surviving earthworks. The dating of this castle is difficult due to the lack of surviving architectural features however the hall type dimensions of the castle ground floor, the lack of cut stone, the high stone vault and the mural stairs all suggest that this castle may have been constructed in the 14th or 15th century. These features along with its close proximity to the Anglo-Norman motte and its association with the Anglo-Norman Tyrrell family also suggest an early medieval rather than a late medieval date for its construction. The castle does not appear to have been several storeys high which suggests that this building may be a transitional style castle bridging the gap between the first floor hall houses of the 13th century and the later multi-storey tower houses of the 15th / 16th centuries. In 1486, Maurice Tirrell [Tyrrell] of Fertullagh, lord of Castleofty [Castlelost], granted to Walter, abbot of St Mary's Abbey, Dublin the advowson of the parish church of Castlelost (WM033-031----) (Gilbert 1884, 18). The 16th century ‘Black Book’ of Archbishop George Dowdall records the castle placename as ‘Veteri Castro [old castle]’ also known as ‘Cremato Castro [burnt castle]’ (Murray 1930, 263). In 1552 this castle was the residence of Thomas Tyrell who was described as being ‘of Castellost, esq., captain of his nation in Fertullaghe, commonly called Tirrell, of Fertullagh; of the captaincy of the country of Fertullaghe; with grant of the manors and lands of Castellost, Perston, Balleforling alias Fardingeston, Ballemccaillen, Gnyvayn alias the white plowe land, Rahyncoill, Kylvrenyn, Midien, Rahynnyen, Kyltoytan, Cloyntyallon, Tyrrellismylton, Shanbaelle alias Oldton, and the Dyrr, county Westmeath. To hold for ever, by the service of one knight’s fee’ (Nicholls 1994, 205). No castle is depicted on the 1654-9 Down Survey parish map of Castlelost (NLI, MS 723-4). The terrier of the Down Survey parish map records that the lands of Castlelost & County Fallonderry amounting to 739 acres of land were in the ownership of ‘Thomas Tirrell’ an Irish papist (ibid.). After the Irish Confederate Wars of 1641-53 the forfeited lands of Thomas Tirrell [Tyrrell] of Castlelost were granted to Margaret Aggs [Aggas] and Sir Jeremy Alexander who are listed as Protestant landowners of Castlelost in 1670.

• WM033-048 Ringfort - rath
  Description

  In level pasture. Circular area (diam. c. 38m N-S; 42.5m E-W) defined by a poorly preserved earthen bank mainly reduced to a scarp enclosed by a deep fosse, earth and stone bank, outer fosse with slight remains of a second external bank only visible from W-N. On S side of the ringfort, the external bank is incorporated into a post-1700 field boundary running E-W. Possible causewayed entrance gap (Wth 2m) at SE. Depicted as a rectangular tree plantation, similar to a moated site on the 1837 ed. OS 6-inch map. On the revised 1910 ed.

• WM033-077 Enclosure - large enclosure
  Description

  Cropmark of possible large trivallate enclosure in grassland on slightly raised ground at the southern end of the field. A small stream lies to the south, the location of which may not be original. A motte (WM033-042----) and later castle (WM33-043----) lie c. 80m to the SE, while a medieval church and graveyard (WM033-031---) lies c. 230m to the north. The monument has been ploughed out. There is no clear trace of the enclosure at ground level. The southern portion of the enclosure appears to have been truncated by a stream course and existing housing. The possible cropmark site enclosure was noted during preparation works for a Community Monument Fund project at Castlelost Church. The cropmark site is only visible on the 2001-2005 MapGenie satellite imagery where it shows the northern portion of a trivallate enclosure. The outer ditch is c. 162m in diameter and the middle ditch is c. 121m in diameter. A tentative inner ditch is c. 77m diameter, while a short section of curvilinear feature between the middle and inner enclosure may represent a low bank or an additional ditch. A stream course cuts through the southern portion of the enclosure with housing along the northern side of the road beyond that. A section of the outer enclosure to the east appears to continue on the southern side of the stream. The cropmark is not visible on later satellite imagery of this area.  No surface remains visible.   Compiled by: Caimin O'Brien based on details provided by archaeologist Steven McGlade of Archaeology Plan archaeological consultancy   Date of Compilation: 10 November 2025
