Thecourt cairn orcourt tomb is amegalithic type ofchambered cairn orgallery grave. During the period, 3900–3500 BC, more than 390 court cairns were built inIreland and over 100 in southwestScotland. TheNeolithic (New Stone Age) monuments are identified by an uncovered courtyard connected to one or more roofed and partitioned burial chambers. Many monuments were built in multiple phases in both Ireland and Scotland and later re-used in theEarly Bronze Age.
Court cairns are characterized as having an uncovered courtyard area connected to one or more covered burial chambers. The boundaries of this open area were typically lined with large standing stones. A narrow, stone-lined entry extended from the main area into one or more roofed burial chambers. Courtyards were generally oval or circular in shape, with U-shaped and semi-circular courtyards being the most common layout. Large standing stones were used to make the walls and roof of burial chambers, normally located at one end of thecairn. Burial chambers are typically divided by jamb stones or jamb-and-sill stones into consecutive burial compartments.[1][2]
There are variations in the court cairn layout in both Ireland and Scotland. Most examples have a single courtyard connected by one burial tomb or a courtyard connected to two burial tombs, located on opposite ends of the court area. In Ireland, there are also instances of layouts with dual tombs, each with its own courtyard, but both sharing a common burial mound. The court cairn is also found in Western Scotland. The similar layout of tombs found in Ireland and Scotland and the close geographical location of these tombs, separated by the narrowIrish Channel, indicates that these populations moved back and forth on a regular basis between the two countries.[3][4]
The earliest megalithic tombs found inBritain, Scotland and Ireland were constructed in early 4th millennium BC. The first burial monuments in these areas were most likely single chamberdolmens surrounded by large standing stones. A few dolmens can be dated in bothWales and Ireland from 3800 to 3500 BC. During the same period,passage graves were being developed throughout Ireland, southwest Britain, theHebrides andthe Orkney Islands. Court cairns are unique to Ireland and Scotland.[5] Radiocarbon dating indicates that the earliest court cairns were built around 3750 and new monuments continued to be built and existing ones enlarged until 2900 BC.[6]
There are over 390 court cairns recorded in Ireland, with a majority of monuments found in the northern third of the island. Irish court cairns have a few variations in layout. Most examples have a single courtyard connected by one burial tomb chamber or a single courtyard connected to a single burial tomb on each end. In Ireland, there are also instances of layouts with dual tombs, each with their own courtyard, but both share a common burial mound and centre court tombs.[7] Most tombs in Ireland are positioned facing east. Less than 40 tombs have been fully excavated to date, and at the majority of sites, at least one cremated individual has been found. In the Audsleystown dual court tomb inCounty Down,Ireland, the remains of 34 people were found in the burial chamber.[6][8]
Court cairns are found north of a line crossing Ireland fromthe Burren to theCooley peninsula. Court cairns are scattered densely across this area of Ireland andNorthern Ireland. Thirty percent of all Irish neolithic monuments are court cairns.[1] The court cairn atCreevykeel inCounty Sligo was the first court cairn to be excavated in Ireland by archaeologists fromHarvard University in 1935. They determined that the Neolithic era in Ireland began in 3900 BC, more than 100 years before the first appearance of court tombs. They also suggested that court tombs were widely re-used during the Early Bronze Age. Excavations of court tombs yielded deposits of cremated and unburnt human bone, round-bottomed bowls, flat-bottomed pottery vessels, flint, polished axes and stone beads.[1]
Burial tombs in Scotland are known asClyde cairns orClyde-Carlingford cairns. Generally considered to be the earliest chambered cairns in Scotland,[9] more than 100 Clyde cairns have been found to date. The "Clyde" name is derived from the first discovery of courtyard type burial monuments in theFirth of Clyde region of southwest Scotland. The ancient monuments are distributed from theSolway Firth area north to the southernHebrides, in the counties ofArgyll andDumfries and Galloway. A few Clyde Cairns have been recorded inNorth Uist in theOuter Hebrides.[2][10]
Clyde cairns found in Scotland are identified by an open courtyard area surrounded with large stone slabs and attached to one or more roofed burial chamber areas. The burial chamber was often placed at one end of a rectangular or trapezoidal cairn,[2] and was usually divided into separate burial compartments. Previous excavations suggest that these chambers were entered by removing the stone roof slabs. In some areas, Clyde cairns have one or more lateral chambers. The majority of these monuments were sited to have views over hills or mountains and over water. Many are situated alongsidelochs. These monuments were often built in multiple phases. Only a few of the Clyde cairns have been fully excavated. Burnt human bone has been found in many Clyde burial chambers. Bowl pottery remnants have also been found. The tombs saw re-use of their burial chambers in the Early Bronze Age.[11]
