Reasons for Designation

Bodmin Moor, the largest of the Cornish granite uplands, has long been recognised to have exceptional preservation of archaeological remains. The Moor has been the subject of detailed archaeological survey and is one of the best recorded upland landscapes in England. The extensive relict landscapes of prehistoric, medieval and post-medieval date provide direct evidence for human exploitation of the Moor from the earliest prehistoric period onwards. The well-preserved and often visible relationship between settlement sites, field systems, ceremonial and funerary monuments as well as later industrial remains provides significant insights into successive changes in the pattern of land use through time.

Long cairns were constructed as elongated rubble mounds and acted as funerary monuments during the Early Neolithic period (c 4000-2400 BC). They represent the burial places of Britain's early farming communities and, as such, are amongst the oldest field monuments surviving visibly in the present landscape. Where investigated, long cairns appear to have been used for communal burial, often with only parts of the human remains having been selected for interment. Long cairns sometimes display evidence of internal structural arrangements, including stone-lined compartments and tomb chambers constructed from massive slabs. Some examples also show edge-set kerb stones bounding parts of the cairn perimeter. Certain sites provide evidence for several phases of funerary activity preceding construction of the cairn and, consequently, it is probable that long cairns acted as important ritual sites for local communities over a considerable period of time. Some 500 examples of long cairns and long barrows, their counterparts in central and eastern England, are recorded nationally, of which six are known from Bodmin Moor. As one of the few types of Neolithic structure to survive as a visible monument and due to their comparative rarity, their considerable age and their longevity as a monument type, all long cairns are considered to be nationally important. Elaborate complexes of fields, field boundaries and linear boundaries are a major feature of the Moor landscape. Several methods of field layout are known to have been employed in south-west England from the Bronze Age to the Roman period (c.2000 BC - 400 AD). These include both irregular and regular aggregate field-systems. Irregular aggregate field-systems comprise a collection of field plots, generally lacking in conformity of orientation and arrangement, containing fields with sinuous outlines and varying shapes and sizes. By contrast, regular aggregate field systems comprise a collection of field plots defined by boundaries laid out in a consistent manner, along two axes at right angles to each other. Both types of field-system are bounded by stone or rubble walls or banks, ditches or fences. They frequently contain small heaps of stone cleared from the surface before or during the plots' use, called clearance cairns. Linear boundaries form land divisions on a larger scale than the field-systems. Built during the Bronze Age (c.2000 - 750 BC), they fulfilled a variety of functions, including separation of cultivated from grazing lands, areas regularly cultivated from those intermittently cultivated, agricultural from ceremonial areas, and territorial markers - separating lands over which rights were exercised by different social groups. Field-systems and linear boundaries are often located around or near settlement sites, visible as stone hut circles, and they sometimes incorporate or occur near ceremonial or funerary monuments which may be earlier than, or contemporary with, the use of the plots and boundaries. Both field-systems and linear boundaries form an important element in the existing landscape and are representative of their period. Their longevity of use and their relationships with other monument types provide important information on the diversity of farming practices and social organisation among prehistoric communities. This monument on Bearah Common has survived well; the long cairn survives substantially intact despite the limited actions of stone robbers and it retains many original features. The field-systems and linear boundaries similarly survive well, preserving their original layout and a good range of broadly contemporary inter-related features including stone hut circles and clearance cairns, with only minor breaks due to stone-splitting and track formation. The presence within the monument of Neolithic, Bronze Age and medieval elements demonstrates well the development of land use over a very considerable time since the Early Prehistoric period. The monument's extensive and varied Prehistoric field-systems and linear boundaries show the nature of farming practices during the Bronze Age and contain rare evidence for their development within the Prehistoric period.

Details

The monument is situated across the broad valley of Bearah Common between Bearah Tor and the Langstone Downs on eastern Bodmin Moor. On the southern slope of Bearah Tor it includes a Neolithic chambered long cairn incorporated within a field of a later Prehistoric regular aggregate field system, itself partly encompassed by a medieval enclosure wall. A wall from the regular field system extends across the valley floor to form one wall of an irregular aggregate field system on the lower northern flank of the Langstone Downs. Another wall from the irregular field system extends as a linear boundary directly up the slope of the Downs, forming a base-line from which four other linear boundaries emerge at intervals running east, dividing the eastern spur of the Downs into near-parallel zones. The Neolithic long cairn survives as a trapezoidal, flat-topped mound of heaped rubble, up to 0.6m high and measuring 28m east-west by 14.5m wide at the east end, tapering to 3m wide at the west end. Limited stone-robbing has produced a hollow, 9m long, 2.5m wide and 0.3m deep, near the centre of the mound's western half and the SW edge of the mound has been truncated by a recently-cut ditch alongside a vehicle track that passes the cairn's southern side. An edge-set slab, 0.5m high, and three contiguous small boulders form a projecting kerb around the NE corner of the platform. The partly collapsed remains of a large slab-built burial chamber are centred 5.5m from the mound's eastern edge. The chamber survives with an edge-set slab, 2.7m long and 1m deep along its north side, against whose southern face leans another slab of the same dimensions which formed the chamber's south side when upright, giving a chamber 2.7m east-west by 1m north-south internally. Against the west and SW edges of the chamber's southern slab are two end-set slabs, called orthostats, each 2.4m long but now reaching 1m and 2m high respectively due to their angle of lean. Three further slabs are laid flat and embedded in the mound's surface to the immediate NE of the chamber, while at least eight more edge-set slabs and small orthostats are visible in the surface of the mound's eastern half, evidence for the internal structuring of the mound common among Neolithic long cairns. One slab lying flat on the mound's SE corner has been fashioned into a millstone roughout during the 19th century. The long cairn is situated near the centre of the eastern field of a Prehistoric regular aggregate field system. This field system includes three rectangular plots bounded by walls of heaped rubble and boulders, generally 1.5m wide and 0.4m high but rising to 3m wide and 1m high in parts, and containing occasional facing slabs and orthostats. The field plots are arranged in a row, WSW-ENE. The smaller eastern pair are defined by three walls, 60-90m apart, sub-dividing the land between two near-parallel walls running 105-125m apart on a WSW-ENE axis, giving plots of 1 hectare and 0.9 hectare respectively. Short lengths of walling extending east from the NE and SE corners of the eastern plot indicate the former presence of further plots in that direction. The western plot comprises a sub-rectangular area of 3.3 hectares, measuring a maximum 197m WSW-ENE by 215m NNW-SSE, its northern wall sharing a similar alignment to that of the eastern plots but its southern wall projecting a further 75m to the SSE. Shorter lengths of rubble walling survive near the centre of its western half, providing evidence for its former sub-division. This field system contains five stone hut circles, surviving with circular rubble walls, up to 2m wide and 0.7m high, around levelled internal areas ranging 5.5-12.5m in diameter. Occasional inner and outer facing slabs are present and one hut circle has a low internal wall marking off the SW third of its interior. One hut circle is located near the northern edge of the eastern field, another is near the SW corner of the western field, and the other three form an east-west line in the NW quarter of the western field. This field system also contains at least 16 large heaps of cleared rubble, called clearance cairns. These range 2-8m in diameter and 0.4-1.2m high, showing a similar distribution to the hut circles with isolated examples at the northern edge and beyond the NE side of the eastern field, one near the SW corner of the western field, and the remainder in the NW quarter of the western field. This field system shows some evidence for re-use as an enclosure during the medieval period; the enclosure wall follows the field system walling along its northern side, then curves south, up to 45m beyond the west wall of the western plot, returning along the southern side of the western plot. No closure of its eastern side is visible. Where the medieval enclosure wall overlies the Prehistoric wall, the latter has been converted into an earth and rubble bank, up to 2m wide and 1m high, ditched along the outer side. The west wall of the Prehistoric regular field system extends south, beyond the field system, to the valley floor where it turns east for 75m, then curves south, rising up the northern lower slope of the Langstone Downs to form the western wall of an irregular aggregate field system. This field system is similarly walled to the regular system and comprises two complete plots. The northern plot is rectangular, 130m long east-west, bounded by parallel walls 45-52m apart to north and south. The southern plot is almost semi-circular, its curving southern wall extending the northern plot's west wall southwards and eastwards to give a length of 110m east-west by 45m north-south. A partly cleared wall marks off a western sector in each plot. The northern wall of the northern plot extends to both east and west. To the east it disappears after 60m into natural rubble deposits. To the west, it continues for 15m beyond the wall extending from the regular system, then turns sharply south, continuing as a major linear boundary described below. A small subrectangular field plot, of 0.04 hectares, is built against this linear boundary's east side, opposite the field system's southern plot. The irregular field system incorporates two stone hut circles, each with rubble walling 2m wide and 1m high, with both inner and outer facing slabs, around levelled interior areas 6.5m in diameter. One hut circle, built into the southern wall of the southern plot, has an entrance gap facing NNW; the other, in the narrow gap between the western plot's west wall and the linear boundary wall, has a south-facing entrance gap. A small clearance cairn is situated 12m north of the latter hut circle, with two others situated adjacent to, and 10m beyond, the southern plot's SE edge. These cairns are up to 4m in diameter and 0.75m high. The linear boundary extending from the northern edge of the irregular field system continues for 357m from its turn southwards, running almost directly uphill for 207m to the shallow summit dome of the spur, and then curving to the SW over its final 150m, ending in the natural boulder scree to the north of Sharptor. The boundary survives as a rubble bank, up to 1.75m wide and 0.4m high, with orthostats up to 0.7m high forming contiguous rows in parts. The boundary forms a base-line from which four other, similarly constructed, linear boundaries extend east and south-east, at intervals of 25-75m, dividing the slope of the spur into broad strips. Shorter cross-walls run SSW from the central two of these boundaries. The parallel walls bounding the northern and southern sides of the irregular field system's northern plot also derive from this earlier phase of land division. The surface of the metalled track running ESE from the Bearah Tor granite quarry is excluded from the scheduling but the ground beneath it is included.
