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 this 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 this monument class nationally. As a rare monument type exhibiting considerable variation in form, a substantial proportion of surviving examples are considered worthy of preservation.

This platform cairn on Dinnever Hill has survived substantially intact. Despite minor disturbance from an unrecorded antiquarian excavation near its centre, this cairn retains clear evidence for its original and unusual form. The proximity of this cairn to other broadly contemporary cairns, ritual monuments, settlement sites and field systems demonstrates well the organisation and development of land use during the Bronze Age and the relationship of funerary practices with settlement and ritual activities among prehistoric communities.


The monument includes a prehistoric funerary platform cairn situated on a slight crest on the northern midslope of Dinnever Hill on north-west Bodmin Moor. The cairn is visible as a circular platform of heaped rubble, 11.5m in diameter, with sides rising steeply to a flat upper surface, 7.5m in diameter and centred slightly south of the cairn's centre. The upper surface is generally 0.5m high, sloping in conformity with the surrounding hillslope, but it is 0.8m on the northern side where the hillslope drops more steeply from the natural crest. The perimeter of the upper surface has a slightly raised rubble rim, 0.75m wide and up to 0.15m high. An unrecorded antiquarian excavation has produced a circular hollow, 4m in diameter and 0.3m deep, in the southern part of the upper surface; spoil from this excavation has been heaped around the northern edge of the hollow. This monument is located in one of several areas of Bodmin Moor that contain an unusually large grouping of prehistoric ritual and funerary monuments. In this grouping, in the vicinity of this monument, other prehistoric cairns of various types are located 250m to the south and 310m to the ENE on Dinnever Hill. Broadly contemporary ritual monuments nearby include the Stannon Stone Circle, 460m to the north-east, within sight of this cairn on an adjacent spur, and a ritual stone setting, 500m to the NNE. Prehistoric hut circle settlements, field systems and linear boundaries are situated on this hillslope from 60m to the north-west and 160m to the east of this monument.
