Passage tombs are a category of Megalithic monument from the Neolithic period. They are found in most regions of Ireland but are more prevalent in the Northern half of the island. The usage period of Irish passage tombs date from c. 3750 B.C. to about 2500 B.C. [1] [2] About twenty clusters are recorded in Ireland, but the best known examples are found along a curved trajectory from the west coast to the east, including the centres of Carrowmore and Carrowkeel in County Sligo, and Loughcrew and the Boyne Valley in County Meath.
The term 'passage tomb' only dates back to the mid twentieth century. [3] Before then, the monuments were called by other terms, such as "chambered cairns" "Danish mounds" or "tumuli". A number of authors of the modern era, including Alison Sheridan and Robert Hensey, have attempted to categorise passage tombs. Hensey suggests three categories; small and simple open monuments, often circular, such as found at Carrowmore, County Sligo; intermediate scale monuments with a cairn covering some form of burial chamber. An example of these would be the Loughcrew passage tombs. This category may have distinctive abstract carvings or petroglyphs in the style of the Irish passage tomb tradition, solar alignments, recumbent kerbs. Burial ritual may include both cremation and deposition of unburnt bones. The third category is exemplified by super monuments similar to Newgrange in the Boyne Valley. These are constructed on a greater scale, possess more elaborate artwork and are architecturally extravagant, incorporating techniques such as corbelling (this is also seen in the second category), long roofed passages, sillstones, and with building materials brought from distant locations. More elaborate passage tomb tradition monuments may have sub-divisions of architectural space; cruciform layouts are well known from Loughcrew, Carrowkeel and the Boyne Valley [4] Sometimes the clusters of monuments have a focal or central monument, bigger than its 'satellites'. This pattern is seen at Knowth and at Carrowmore. There is often structure on an even larger scale associated with landscape features such as lakes, rivers and mountains observed in the layout. For instance at Carrowkeel, Sligo, a smaller cluster in the Bricklieve Mountains has a number of outlying sites such as the Pinnacle on Keash Hill, Ardloy, Heapstown and Suigh Lughaidh [5] One feature of Irish passage tombs that distinguishes them from other monumental types of the Neolithic era is the longevity of the tradition. They appear to be in use for well over a millennium, in contrast to other monument types associated with the early Neolithic, such as court tombs or portal dolmens.
Burials in Irish passage tombs tend to be accompanied by a limited and distinctive range of objects. These grave goods include pins fashioned from bone or red deer antler, carved and polished stone pendants, pieces of quartz, flint or chert tools, stone or chalk balls and a distinctive form of pottery called Carrowkeel ware, named thus because it was first noted in Carrowkeel. The pots, formed of reddish clay, are fashioned in a variety of sizes, but are always round-bottomed, and often decorated with stab and drag patterns. Few intact examples have been recovered, but these include some fine examples from the Mound of the Hostages (Dumha na nGiall) passage tomb at the Hill of Tara, County Meath [6]
After his excavation and restoration work at Newgrange, Michael O'Kelly reported his discovery of a solar alignment on the winter solstice. Such alignments have been claimed for monuments in different parts of Ireland and abroad, for example in Maes Howe, Scotland; Loughcrew, County Meath; Knockroe, County Kilkenny and in Listoghil, the central monument at Carrowmore, County Sligo, [7] [8]
The Irish passage tombs bear similarities to examples found in other locations on the Atlantic facade; in particular in Brittany, France; Wales and Scotland. Ancient DNA research has associated the dead in the Irish monuments with early farming migrations to the Atlantic region about 6000 years ago. [9] The ancient ancestral origin of these groups was Anatolia. Familial connections between people buried at Carrowmore, Carrowkeel, Millin Bay and Newgrange have been demonstrated, and the passage tomb populations appear to cluster (in genetic terms) away from occupants of other neolithic monuments and the general Irish neolithic population. This (and an indication of incest in the genetic profile of a male interred in the right recess of Newgrange) has led a team of researchers in Trinity College Dublin to propose that Irish neolithic society was led by dynastic rulers. Lara Cassidy stated, "It seems what we have here is a powerful extended kin-group, who had access to elite burial sites in many regions of the island for at least half a millennium". [10] [11]
Although some of the more high profile Irish passage tombs have been excavated and - sometimes controversially - reconstructed, many monuments remain unexcavated. Many hill cairns and lowland cairns may be passage tombs; monuments such as Shee Mór in County Leitrim, Heapstown in County Sligo and Croghaun, near Raphoe in County Donegal.
A passage grave or passage tomb consists of one or more burial chambers covered in earth or with stone, and having a narrow access passage made of large stones. These structures usually date from the Neolithic Age, and are found largely in Western Europe. When covered in earth, a passage grave is a type of burial mound which are found in various forms all over the world. When a passage grave is covered in stone, it is a type of cairn.
Newgrange is a prehistoric monument in County Meath in Ireland, located on a rise overlooking the River Boyne, 8 kilometres (5.0 mi) west of Drogheda. It is an exceptionally grand passage tomb built during the Neolithic Period, around 3200 BC, making it older than Stonehenge and the Egyptian pyramids. It is aligned on the winter solstice sunrise. Newgrange is the main monument in the Brú na Bóinne complex, a World Heritage Site that also includes the passage tombs of Knowth and Dowth, as well as other henges, burial mounds and standing stones.
The Hill of Tara is a hill and ancient ceremonial and burial site near Skryne in County Meath, Ireland. Tradition identifies the hill as the inauguration place and seat of the High Kings of Ireland; it also appears in Irish mythology. Tara consists of numerous monuments and earthworks—dating from the Neolithic to the Iron Age—including a passage tomb, burial mounds, round enclosures, a standing stone, and a ceremonial avenue. There is also a church and graveyard on the hill. Tara forms part of a larger ancient landscape and Tara itself is a protected national monument under the care of the Office of Public Works, an agency of the Irish Government.
Dowth is a Neolithic passage tomb located in the Boyne Valley, County Meath, Ireland. It is one of the three principal tombs of the Brú na Bóinne World Heritage Site – a landscape of prehistoric monuments including the large passage-tombs of Dowth, Newgrange and Knowth. Unlike Newgrange and Knowth, Dowth has not been independently dated, but its features align it with the other passage tombs which date from between approximately 3200 and 2900 BC. However, Harbison (1970) dates the tomb at 2500 – 2000 BC. It is less developed as a tourist attraction than its neighbours, partly because the chamber is much lower, and partly because the decoration is less visible. It was partly excavated, in 1847 by the Royal Irish Academy who dynamited the roof causing the still visible crater, though it was pillaged by Vikings and earlier looters long before that.
Loughcrew or Lough Crew is an area of historical importance near Oldcastle, County Meath, Ireland. It is home to a group of ancient tombs from the 4th millennium BC, some decorated with rare megalithic art, which sit on top of a range of hills. The hills and tombs are together known as Slieve na Calliagh and are the highest point in Meath. It is one of the four main passage tomb cemeteries in Ireland and is a protected National Monument. The area is also home to the Loughcrew Estate, from which it is named.
The Mound of the Hostages is an ancient passage tomb located in the Tara-Skryne Valley in County Meath, Leinster, Ireland.
Knowth is a Neolithic passage grave and an ancient monument of the World Heritage Site of Brú na Bóinne located 8.4 km west of Drogheda in Ireland's valley of the River Boyne. It is the largest passage grave of the Brú na Bóinne complex. It consists of a large mound and 17 smaller satellite tombs. The mound is about 12 metres (40 ft) high and 67 metres (220 ft) in diameter, covering roughly a hectare. It contains two passages placed along an east-west line and is encircled by 127 kerbstones, of which three are missing, and four badly damaged.
Carrowmore is a large group of megalithic monuments on the Cúil Iorra Peninsula to the west of Sligo, Ireland. They were built in the 4th millennium BCE, during the Neolithic era. There are thirty surviving tombs, making Carrowmore one of the largest clusters of megalithic tombs in Ireland. It is considered one of the 'big four' along with Carrowkeel, Loughcrew and Brú na Bóinne. Carrowmore is the heart of an ancient ritual landscape which is dominated by the mountain of Knocknarea to the west. It is a protected National Monument.
Listoghil is the large central monument in the Carrowmore group of prehistoric tombs in County Sligo in Ireland. It was numbered as Carrowmore 51 by George Petrie in 1837 and this designation is still used. Although the district of Cuil Irra is steeped in legend, Listoghil has never been satisfactorily connected with the ancient legends in the way that say Newgrange has. It is the only cairn in Carrowmore. Antiquarians in the 19th century made references to another cairn nearby at Leacharail, but the site of this has never been located.
Knocknarea is a large prominent hill west of Sligo town in County Sligo, Ireland, with a height of 327 metres (1,073 ft). Knocknarea is visually striking as it has steep limestone cliffs and stands on the Cúil Irra peninsula overlooking the Atlantic coast. At the summit is one of Ireland's largest cairns, known as Queen Maeve's Cairn, which is believed to contain a Neolithic passage tomb. In recent years there has been concern that the ancient cairn, a protected National Monument, is being damaged by climbers. There are also remains of several smaller tombs on the summit. Knocknarea overlooks the Carrowmore tombs and is thought to have been part of an ancient ritual landscape.
Brú na Bóinne or Boyne valley tombs, is an area in County Meath, Ireland, located in a bend of the River Boyne. It contains one of the world's most important prehistoric landscapes dating from the Neolithic period, including the large Megalithic passage graves of Knowth, Newgrange and Dowth as well as some 90 additional monuments. The archaeological culture associated with these sites is called the "Boyne culture".
The Newgrange cursus is an Neolithic monument used as a ceremonial procession route within the Brú na Bóinne complex. The ancient trackway is 100m long and 20m wide. It is located at Newgrange, in County Meath, Ireland.
Corn Hill, also called Cairn Hill or Carn Clonhugh, is a hill in County Longford, Republic of Ireland. It lies north of Longford, between Drumlish and Ballinalee, in the parish of Killoe. At 278 metres above sea level, it is the highest hill in the county and has a television mast on the top which rises 123 metres above the peak of the hill.
The Brú na Bóinne Visitor Centre is the starting point for all visits to the monuments of the UNESCO World Heritage Site at Brú na Bóinne, notably the passage graves of Newgrange and Knowth. It is located eight kilometers west of Drogheda in County Meath, Ireland.
Carrowkeel is a cluster of passage tombs in south County Sligo, Ireland. They were built in the 4th millennium BC, during the Neolithic era. The monuments are on the Bricklieve Hills, overlooking Lough Arrow, and are sometimes called the Bricklieve tombs. They are named after the townland of Carrowkeel in which most of them are located. Nearby are the Caves of Kesh and Heapstown Cairn. The Carrowkeel tombs are protected National Monuments and are considered one of the "big four" passage tomb cemeteries in Ireland, along with Carrowmore, Brú na Bóinne and Loughcrew.
Megalithic monuments in Ireland typically represent one of several types of megalithic tombs: court cairns, passage tombs, portal tombs and wedge tombs. The remains of over 1,000 such megalithic tombs have been recorded around Ireland.
Slieve na Calliagh are a range of hills and ancient burial site near Oldcastle, County Meath, Ireland. The summit is 276 metres (906 ft), the highest point in the county. On the hilltops are about twenty passage tombs, some decorated with rare megalithic art, which were built in the 4th millennium BC. Also called the Loughcrew tombs, it is one of the main passage tomb cemeteries in Ireland, along with Brú na Bóinne, Carrowkeel and Carrowmore.
British megalith architecture is the study of those ancient cultures that built megalithic sites on the British Isles, including the research and documentation of these sites. The classification sometimes used of these cultures based on geological criteria is problematic.
Heapstown Cairn is a cairn and National Monument located in County Sligo, Ireland.
Knockroe Passage Tomb is a prehistoric site, of the Neolithic period, in the townland of Knockroe in County Kilkenny, Ireland, about 10 km north of Carrick-on-Suir. It is known locally as "The Caiseal".
