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.

Platform cairns are funerary monuments covering single or multiple burials and dating to the early Bronze Age (c.2000 - 1600 BC). They were constructed as low flat-topped mounds of stone rubble up to 40m in external diameter. Some examples have other features, including peripheral banks and internal mounds constructed on the platform. A kerb of edge-set stones sometimes bounds the edges of the platform, bank or mound or all three. Platform cairns occur as isolated monuments, in small groups or in cairn cemeteries. In the latter instances they are normally found alongside cairns of other types. Although no precise figure is available, current evidence indicates that there are under 250 known examples of platform cairns nationally. Stone alignments or stone rows consist of upright stones set in a single line, or in two or more parallel lines, up to several hundred metres in length. They are often sited close to Prehistoric burial monuments, such as small cairns and cists, and to ritual monuments, such as stone circles, and are therefore considered to have had an important ceremonial function. The eight stone alignments known on Bodmin Moor are considered to date from the late Neolithic to early Bronze Age periods (c.2500 - 1600 BC). Both platform cairns and stone alignments are rare monument types which each exhibit considerable variation in form and associations and which provide important insights into funerary and ritual practices among Prehistoric communities on the Moor.

This platform cairn and the adjacent stone alignment have survived well, with only minor damage from the antiquarian excavation and stock erosion. Such an overlapping association between a cairn and a stone alignment is very rare and important for understanding the relationships between these types of monument. The proximity of the monument to other, broadly contemporary, funerary and ceremonial monuments demonstrates well the nature and diversity of funerary and ritual activities during the later Neolithic and Bronze Age periods, while the association of this cairn with another platform cairn, of a different form, on the hill's summit is also very rare.

The monument includes a kerbed platform cairn with a central mound, from whose NNW periphery extends a Prehistoric stone alignment. The monument is situated on the summit of the central hill of East Moor on eastern Bodmin Moor, forming one element of a local concentration of broadly contemporary ceremonial and funerary monuments. The monument is divided into three separate areas. The cairn survives as a turf-covered flat-topped platform of heaped rubble, 14m in diameter and up to 0.6m high. Against the steep edge of the platform is a kerb of nine edge-set slabs, up to 0.75m high and 1.4m wide, grouped to form three widely-spaced pairs at the east, south and west sectors, with isolated kerb slabs at the north-east and north-west. Three hollows at the east side, one with packing stones visible in its base, mark the former locations of further kerb slabs. At the centre of the platform is a circular mound of heaped rubble, 5.5m in diameter and rising 0.5m above the level of the platform. A 2m diameter central area of the mound has several small hollows, up to 0.25m deep, resulting from an early unrecorded antiquarian excavation. These hollows reveal four stone slabs, the largest of which, an edge-set slab 1m long, 0.2m thick and projecting 0.4m high, is considered to derive from an internal structure of the mound. On the NNW periphery of the platform is an elongated narrow slab, 2.2m long, 0.5m wide and 0.4m thick at its midpoint, tapered to both ends with a wedge-shaped SSE edge. The slab lies flat on the platform surface, with its long axis orientated NNW-SSE. Some stock erosion around the western side of the slab's base reveals a quantity of small stones packing the slab in place. This slab is matched by an almost identical slab situated in an otherwise stone-free area 287m to the south-west. That slab is 2.7m long, 0.4m wide and 0.3m thick, tapered to a wedge-shaped south-west edge. The slab also lies flat on the ground, its long axis orientated NE-SW and surrounding stock erosion reveals packing stones about its base. The NE-SW stone alignment is completed by a third slab, 47m south-west of that on the cairn's periphery and directly in line between the two recumbent slabs. This slab is 1m long and 0.2m wide, edge-set and stands 0.75m high with its NE-SW long axis matching the orientation of the alignment. Stock erosion also reveals packing stones about its base. This intermediate slab is situated on the south-west crest of the hill's summit at the only point from which the slabs at each end are visible. Beyond this monument, the broadly contemporary sites nearby on the hill's summit include a large embanked platform cairn 60m to the north-west and a second stone alignment whose SSW slab is 52m north-west of that platform cairn.

MAP EXTRACT The site of the monument is shown on the attached map extract. It includes a 2 metre boundary around the archaeological features, considered to be essential for the monument's support and preservation.
