Irish round tower
- This is about Irish-style round towers. See Round tower (disambiguation) for other types of towers.
Irish round towers (Irish: Cloigtheach (singular), Cloigthithe (plural) – literally "bell house") are early medieval stone towers of a type found mainly in Ireland, with two in Scotland and one on the Isle of Man. As their name Cloigtheach indicates, they were originally bell towers, though they may have been later used for additional purposes.
Generally found in the vicinity of a church or monastery, the door of the tower faces the west doorway of the church. In this way it has been possible to determine without excavation the approximate site of lost churches, where the tower still exists.
Construction and distribution
Surviving towers range in height from 18 metres (59 ft) to 40 metres (130 ft), and 12 metres (39 ft) to 18 metres (59 ft) in circumference; that at Kilmacduagh being the highest surviving in Ireland (and leaning 1.7 metres (5 ft 7 in) out of perpendicular). The masonry differs according to date, the earliest examples being uncut rubble, while the later ones are of neatly joined stone work (ashlar). The lower portion is solid masonry with a single door raised two to three metres above, often accessible only by a ladder. Within, in some, are two or more floors (or signs of where such floors existed), usually of wood, and it is thought that there were ladders in between. The windows, which are high up, are slits in the stone. The cap (roof), is of stone, usually conical in shape, although some of the towers are now crowned by a later circle of battlements.
The main reason for the entrance-way being built above ground level was to maintain the structural integrity of the building rather than for defence. The towers were generally built with very little foundation. The tower at Monasterboice has an underground foundation of only sixty centimetres. Building the door at ground level would weaken the tower. The buildings still stand today because their round shape is gale-resistant and the section of the tower underneath the entrance is packed with soil and stones.
The distance from the ground to the raised doorway is somewhat greater than that from the first floor to the second; thus large, rigid steps would be too large for the door. Excavations in the 1990s, revealing postholes, confirm that wooden steps were built. However, the use of ladders prior to the construction of such steps cannot be ruled out.
The towers were probably built between the 9th and 12th centuries. In Ireland about 120 examples are thought once to have existed; most are in ruins, while eighteen to twenty are almost perfect. There are three examples outside Ireland. Two are in north-eastern Scotland: the Brechin Round Tower and the Abernethy Round Tower, and the other is in Peel Castle on St. Patrick's Isle, now linked to the Isle of Man.
Famous examples are to be found at Devenish Island, and Glendalough, while that at Clondalkin is the only Round Tower in Ireland to still retain its original cap. With five towers each, County Mayo, County Kilkenny and County Kildare have the most. Mayo's round towers are at Aughagower, Balla, Killala, Meelick and Turlough, while Kildare's are located at Kildare Cathedral (which is 32 metres (105 ft) high), and also at Castledermot, Oughter Ard, Taghadoe (near Maynooth) and Old Kilcullen. The only known round tower with a hexagonal base is at Kinneigh in County Cork, built in 1014. The round tower at Ardmore, County Waterford, believed to be the latest built in Ireland (c. 12th century), has the unique feature of three string courses around the exterior.

The purpose of the towers has been somewhat unclear until recent times. A popular hypothesis in the past was that the towers were originally a redoubt against raiders such as Vikings. If a lookout posted in the tower spotted a Viking force, the local population (or at least the clerics) would enter, using a ladder which could be raised from within. The towers would be used to store religious relics and other plunderables. However, there are many problems with this hypothesis. Many towers are built in positions which are not ideal to survey the surrounding countryside and would not work efficiently as watch towers for incoming attacks.
In addition, the doors to these towers would have been wooden and therefore easily burned down. Furthermore, due to the almost chimney-like design of the towers, the smoke from the burning door would have been carried upwards inside the tower causing any occupants to suffocate. Indeed, the round towers at Dysert O'Dea and Aghagower show evidence of fire damage around the doorway. There are also records of people being burned to death in round towers.
Therefore, it is more likely that the primary reason for the round tower was - as the name cloigtheach indicates - to act as a belfry. The Irish word for round tower, cloigtheach, literally meaning bellhouse indicates this, as noted by George Petrie in 1845. The Irish language has greatly evolved over the last millennium. Dinneen notes the alternate pronunciations, cluiceach and cuilceach for cloigtheach. The closely pronounced cloichtheach means stone-house or stone-building. The round tower seems to be the only significant stone building in Ireland before the advent of the Normans in AD 1169-71.
UCD Professor of Archaeology Tadhg O'Keeffe has suggested that the towers were originally high status royal chapels, citing how two of them (Kells and Duleek) were scenes of regicide. He also suggested that the windows were arranged clockwise to imitate the order of relic-carrying procession from the elevated door to the very top.
Modern symbolic towers
At what is now the Irish National Heritage Park at Ferrycarrig in County Wexford, there is a 19th-century copy of a round tower. It was erected to the memory of the Wexford men who fell in the Crimea War.
In the Knockmealdown Mountains in County Waterford is another memorial in the form of a 18m high round tower. It was erected in 1935 on the spot where Liam Lynch, military leader of the anti-treaty Irish Republican Army during the Irish Civil War is thought to have fallen in 1923.
The Ulster History Park in County Tyrone has a replica of a round tower.
Another "revival" round tower was built in 1997 in the Island of Ireland Peace Park in Belgium, as a war memorial to the soldiers of the island of Ireland who died, were wounded or are missing from World War I. The 110-foot (34 m) tower is in the traditional design of an Irish round tower and is partially built with stone from a former army barracks in Tipperary.
At Saint Mary's Cemetery in Milford, Massachusetts a round tower was built of Milford granite in the late 19th century as a memorial to central Massachusetts' Irish immigrants, of whom thousands are buried there. In 2003 Tony Ryan, a native of Thurles, County Tipperary, built a round tower at his Castleton Lyons Stud in Kentucky.
The second church to be built on the site of St John the Evangelist Catholic Church in East Melbourne, Victoria, Australia, completed in December 1900, features a 13-metre Irish round tower on its eastern side. The tower is based on the entrance to King Cormac's Chapel on the Rock of Cashel in Tipperary, built in 1137. The structure is now part of the Catholic Leadership Centre, operated by the Catholic Education Office Melbourne.
List of Irish round towers
The following is a list of surviving Irish round towers, excluding modern reconstructions.
|Aghadoe||Kerry||Munster||Incomplete||5.4 metres (18 ft)|

A stump 3m tall at its highest point, surrounded by rubble from its collapse, is all that remains. Barrow speculates that some of the stones from the tower were used to build the nearby wall surrounding the cemetery, including one at the top of the entrance 1.07m long with a raised moulding that may have been the sill stone from the tower's doorway.
|Ardrahan||Galway||Connacht||Incomplete||3 metres (9.8 ft)|

The tower is said to have survived the siege of 1689 but seemed to have disappeared. In 2018, a local ruin (previously believed to be an old windmill) was identified as being the missing tower.
The OS of County Londonderry of 1837 Has the following: "In the charter of Derry it is called Columb kille's Tower In Raven's plan of the city in 1621 it appears as a very high and slender belfry....In the popular traditions of Derry and its vicinity this tower is still invariably spoken of as a lofty round tower built by St Columb himself and many legends are current of its miracle working silver bell"

List of missing towers
This is a list of Irish round towers known to have existed, but no trace now remains.
|Name||County||Year||Notes: taken from George Lennox Barrow's The Round Towers of Ireland 1979 and Brian Lalor's The Irish Round Tower-Origins and Architecture Explored 1999 unless otherwise stated|
|Annadown||Galway||1238||Lalor states that there is a reference from The Annals of the Four Masters for the year 1238 "The Cloicteach of Enachduin was erected". All trace of the tower has vanished|
|Ardbraccon||Meath||1181||The Annals of Clonmacnoise for the year 1181 record "The steeple of Ardbreakean fell this yeare". No trace of the tower now remains.|
|Ardfert||Kerry||1771||The tower fell in a great storm in 1771. Descriptions of the tower vary with Samual Molyneux passing the tower in 1709 stating that it was "very low" with seamen often mistaking it for Scattery round tower. Charles Smith in 1756 describes the tower as being near 100 ft (30m) tall being mostly constructed of "a dark kind of marble" and "not composed of freestone", "the finest [tower] I have met with". Later accounts in 1878 (O Halloran) and 1884 (Tralee Chronicle) put its height at 120 ft and 150 ft respectively. The Parliamentary gazetteer of Ireland 1846 states that the tower was "slated" (but being written over 70 years after it fell it is difficult to say for certain if this was so, if it was it would certainly be a unique feature).
Brain Lalor states that fragments of the tower have been found onsite and its location is marked on OSI maps from c. 1850.
|Armagh||Armagh||1121||There are several references to this tower from the annals:|
995/6 "Ard-Macha was burned by lightning, both houses damhlaig and cloigteach and fidnad" - Annals of Tigernach
|Brigown (near Mitchelstown)||Cork||1720||Barrow's research indicates that this tower collapsed in a storm in 1720, and the remaining stump (around 4.6 m tall) disappeared by degrees with the last dug out in 1807 and the stones used to build a local glebe house. The tower reputably stood around 18 m to the south-west of the ruined church. |
No trace of the tower remains.
|Clonard||Meath||1039||The Annals of the Four Masters for the year 1039 records "The Cloicteach of Cluain-Iraid fell" |
This is the only known reference to the tower and no trace of the it now remains.
|Cork||Cork||1738||Barrow's evidence indicates that this tower fell in 1738. A French traveller, Boullaye le Gouz passing it in 1644 describes the tower as "dix ou douze pas de circuit et plus de 100 pieds du hait" (10 or 12 paces around and over 100 feet tall). An engraving on the foot of a moonstrance (dating from 1669) in the Dominican friary at Pope's Quay, Cork depicts St. Fimbar with a church behind him and a capless round tower at one end. The tower has a broken top with 6 windows directly in line above a round-headed doorway.
No trace of the tower now remains and the cathedral built in 1865 evidently covers the site where it once stood.
|Downpatrick||Down||1015||The Annals of the Four Masters for the year 1015 record "Dun-de-leathghlas was totally burned with its Daimhlaig and its Cloicteach by lightning" |
Harris (from Ware's Antiquities 1746) in 1744 describes the remains of the tower at that time as being 66 feet tall with walls 3 feet thick standing 40 ft from the old cathedral. The doorway was at ground level. (Barrow speculates that the ground level may have been raised by the rubble of the old cathedral.)
A painting by Charles Lilly from 1790 and a print from 1789 show the round tower with a broken top standing to the south-west corner of the cathedral next to St. Patrick's grave. The remainder of the tower is said to have been pulled down in the early 19th century during the renovation of the cathedral as it was in a dangerous state.
|Dublin, St Michael Le Pole||Dublin||1775||The tower stood in an old churchyard just south west of Dublin castle. In 1706 the Dean of St. Patrick's Cathedral granted the ruins of the church (where the tower stood) to Dr. John Jones to build a school, with one of the conditions being that he would not pull down the tower. The formerly free-standing tower then had the school built around it. Drawings by Beringer from 1766 and 1776 show this school building with the tower projecting through the west end of the roof. in 1775 the tower was badly damaged by a storm and the Dean and Chapter agreed that it must be taken down because it was too dangerous to repair. This was done 3 years later with the upper portion of the tower removed down to the level of the church roof. It is unclear when the remainder of the tower was demolished, though this was possibly done in 1789.
Barrow states that Petrie in his notes (c. 1830s) quotes old locals describing the tower as of rude construction of large stones c.70 ft high with two windows at the top. A car park now marks the site of the former school and no trace of the tower now remains, though its stones are said to have been used in a nearby cemetery wall (this wall is no longer present).
|Duleek||Meath||1147||The Annals of the Four Masters for the year 1147 record "A thunderbolt fell this year upon the cloicteach of Daimhliag-Chianain and knocked off the beannchobhair (conical cap)"
The tower survived at least until medieval times. Evidence of this is clearly visible in the imprint of the tower in the north wall of the square 15th century Tower of St. Mary's Church. The tower was incorporated into the medieval belfry in a similar manner to the Irish Round Tower at Lusk. The tower collapsed or was demolished at an unknown date leaving a scar in the side of the belfry. The scar rises to 14 m high where the tower diverged from the later building. There is a large window/opening (9.6 m from the ground) within this scar suggesting that this opening allowed access between the tower and belfry.
Fragments of the foundation remain showing that the external diameter at the base of the tower was 5.18 m.
|Emly||Tipperary||1058||The Annals of the Four Masters for the year 1058 record "Iarleach-Ibhair was totally burned Daimhliag and Cloicteach"
Thomas Dineley in his book from 1681 has a sketch of the old cathedral at Emly with a stump (possibly that of the remains of a round tower) behind it at one side reaching to the height of the eaves of the cathedral. The stump appears to have 11 regular even courses of masonry with an opening, possibly representing the doorway. The site of the cathedral is an old graveyard beside the modern catholic church.
All that remains of the cathedral is an old stone cross and no trace of the tower remains.
|Kilbarry||Roscommon||1770s||John O'Donovan speaks of meeting a local man in 1837 who remembers the round tower of Kilbarry standing. It is said to have stood around 15 feet west of the church in the monastery of Clooncoirpthe. The tower fell in a great storm in the 1770s, and in doing so knocked down the closest corner of the church. This corner was known as Claig-theach corner. The tower had a diameter of 9–11 feet and the last remains of it were removed 6 years before O'Donovan's visit.
Barrow visiting the site in 1974 describes finding several stones taken from the ruin of the round tower embedded in the cemetery wall surrounding the site and also scattered amongst the graves. These stones include the capstone, a conical stone with an angle of around 65 degrees 30 cm high with one side broken off. Also found were what Barrow believes were the remains of a round headed doorway "of three stones" dressed to the curve with a moulding.
|Kellistown||Carlow||1807||Anthologia Hibernica Volume 4 (1794) (which refers to the place as "Kellet's Town") states "The tower which stands on elevated ground about five miles NE of Carlow and not on the Barrow as asserted in some late publications is built of grit stone with which the country abounds and about twelve feet internal diameter but at present much destroyed" A sketch of the ruin of this tower is also in this book. It depicts the tower standing about 10m tall with 23 stone courses, broken down its left side to ground level, with a breach near the top which could represent the remains of a window.
A Topographical Dictionary of Ireland states "One of the ancient round towers stood here till 1807 when it was pulled down to make room for the belfry of the church".
|Killeshin||Laois||1703||The monastic site at Killeshin, 5 km west of Carlow, contains the remains of a 12th-century church. The round tower is said to have stood 20 m south west of this church.
The Royal Society of Antiquaries of Ireland describes the steeple of Killeshin being "undermined" "and flung down" in 1703 by an employee of a Captain Woosley (described as "Hero of the Boyne"). The tower measured 105 feet long on the ground after being felled and apparently remained largely intact in its tubular form.
John O'Donovan was told by locals in 1838 that the tower was knocked down by the local landlord in c. 1750 as it posed a threat (if it fell) to his cattle who used to scratch themselves on the four pillars on which the tower stood. Barrow speculates that this later account of the towers destruction and 4 pillars notion is a corruption of the original account and speculates that the tower had become dilapidated at its base and so became structurally unsound. Stones from the tower were still visible on site during O'Donovan's visit in 1838.
Barrow states that nothing now remains of the tower, "at least above the ground".
|Raphoe||Donegal||1660||In James Moore's 1739 book Ware states that "There was also in that Place a round Tower built on a Hill in which the Bishops of Raphoe formerly kept their Studies". Barrow states that there is a manuscript in the Ware's handwriting dated 2 April 1660, that Dr. John Leslie, bishop of Raphoe, had told him that he caused a round tower, or pyramid build of old times to be pulled down and the stones used for his new "epall house". In the bottom of the tower he found the bones of a man buried anciently there. Barrow states that the "Bishop's House", now a burnt out ruin, was built by Leslie in 1637. The traditional site of the tower is now pointed up a lane to the north-west of the Cathedral.
Barrow speculates that a farm wall nearby may contain stones from the round tower.
|Rath Blamaic||Clare||1838||A ruined medieval church marks the site of the monastery said to be founded by St. Blamaic in the 6th century. It is a mile NNW of the round tower at Dysert O Dea which is clearly visible across the valley.
Keane says: The ruins of a Round Tower to the height of eight feet and without door or window are said to have stood at Rath until the year 1838 when the materials were removed for the building of the Church yard wall . Keane also says There is a legend among the peasantry of the neighbourhood that the Saint of Dysart, St Mawnaula, carried away from Rath the tower now standing at Dysart whereupon Blamaic the Saint of Rath retaliated by conveying to Rath some other building which had stood at Dysart. Barrow speculates that it is more likely that the tower and indeed the entire monastery at Dysart was built to replace the one that had been ruined at Rath Blamaic. Barrow also states that when he examined the cemetery wall, in 1974, at Rath Blamaic that many of its stones looked likely to have come from the remains of the round tower.
|Rosscarbery||Cork||1285||The Annals of Inisfallen for the year 1285 record A very destructive wind this year, about the feast of Brigid [Feb 1st]; It blew down the bell tower of Ross Ailithir and caused much damage generally.
Barrow states that the Silver seal of the dean and chapter of Ross, made in 1661, was embossed with a round tower which had a bulge at its base like Clondalkin. The site at Rosscarbery is now marked by a Church of Ireland cathedral with the remains of an early church across the road. No trace of the round tower remains.
|Slane||Meath||948||The Annals of the Four Masters for the year 948 record The Belfry of Slane was burned by the foreigners [The Danes], with its full of relics and distinguished persons. together with Caeineachair, Lector of Slaine, and the crosier of the patron saint and a bell, the best of bells (this is the earliest reference in the known Annals to an Irish round tower).
Barrow speculates that the probable site of the tower was on a hill where the ruins of a 16th-century friary now remain. No trace of the tower remains.
|Tomregon||Cavan||The site of at Tomregon is located around 4 km south west of Ballyconnell in an open field known as the Church Meadow. Traces of the foundations of the tower and church were reported in 1948. Davies claims that a stone on the site carved with a human head, legs, arms but no body, looks like it came from an arch from the tower. Barrow discounts this possibility as the arch stone would be too small for such purpose but may have come from the ruined church.
Nothing visible remains above ground at least.
|Trim||Meath||1126–7||The Annals of Ulster for the year 1126–7 record A great hosting by Connor MacFergall O'Loughlinn together with the people of the North of Ireland, to Meath; They burned Trim, both cloicteach and church and these full of people.
It is presumed by locals that the tower stood on the site of the Church of Ireland cathedral. No other references to the tower exist and no trace of the tower remains.
|Tuamgraney||Clare||964||The Annals of Chronicum Scotorum for the year 964 record Cormac Ua Cillin, of the Ui Fiachrach Aidhne, comarb of Ciaran and Coman, and comarb of Tuaim-greine, by whom the great church of Tuam-greine, and its cloicteach, were constructed, sapiens et senex, et Episcopus, quievit in Christo. This is the earliest reference in the known annals to the building of an Irish round tower.
George Petrie recorded a local tradition that some of the tower remained till as late as 1800. Barrow states that Brash, however, upon visiting the area in 1852 and speaking with its oldest inhabitants was unable to find anyone with knowledge of the tower. Brash speculates that the Petrie may have been referencing an old stone church rather that the remains of a round tower. It is unknown where exactly the tower stood and no trace of it remains.
|Tullaghard||Meath||1171||The Annals of Four Masters for the year 1171 record The cloicteach of Tealach-aird was burned by Tighearnan Ua Ruairc, with its full of people in it.
John O'Donovan identifies the site as in the townland of Tullaghard of Steeplestown a short way due North of Trim. O'Donovan also records speaking to a local person born in 1750 who claimed to remember the tower standing as late as 1757. He had seen it as a child but was unable to recall what kind of tower it was. Barrow states that the site is now "open fields" and no trace of the tower remains.
|Tullamaine||Kilkenny||1121||The Annals of Four Masters for the year 1121 record The cloicteach of Tealach-nInmainne in Osraighe was split by a thunderbolt and a stone flew from the cloicteach, which killed a student in the church.
John O'Donovan identifies the site as Tullamaine, a parish whose overgrown closed cemetery is in a field about 4 km West of Callan. No monastic remains now exist there and no trace of the tower remains.
