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 the Carkeet Downs has survived reasonably well despite the limited disturbance by recent stone-robbing from the surface of the central mound and the modern hedgebank which clips the platform's eastern periphery. Most of the cairn's platform and much of its mound, internal deposits and its extensive buried land surface will survive substantially intact. The form of this cairn, with its kerbed central mound on a low platform, is unusual. The proximity of this monument to the other cairns on the summit of the Downs and its relationship with the various hilltop cairns of differing forms bordering the Fowey valley demonstrates well the nature and diversity of funerary practices during the Bronze Age.


The monument includes a prehistoric platform cairn with a central mound situated near two other broadly contemporary cairns on the summit of the Carkeet Downs at the south-west edge of Siblyback Moor on south-east Bodmin Moor. The platform cairn survives with a circular raised platform of turf-covered heaped rubble, 15.5m in diameter and up to 0.4m high. About the centre of the platform, a distinct mound, 9m in diameter, rises to 0.8m high. The outer edge of the mound is defined along its western half by a slight kerb of small edge-set stones, up to 0.1m high, visible in the turf. The centre and southern half of the central mound bears traces of an east-west trench and various irregular hollows, up to 0.3m deep, due to relatively recent stone-robbing for a modern ditched hedgebank which runs NNE-SSW across the eastern periphery of the cairn's platform. A small heap of unconsolidated rubble on the mound's southern half has been recently dumped after stone-clearance in the neighbouring pasture. This monument is situated near two other broadly contemporary cairns located 28m to the NNE and 125m to the ESE respectively on the broad summit of the Carkeet Downs. This group of three cairns forms part of a sequence of prehistoric funerary cairns, of various forms, located on successive ridge tops bordering the western side of the upper valley of the River Fowey. In this series, this monument is located c.600m south of a round cairn on the next ridge to the north and c.900m north of another cairn group on the next ridge to the south.

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.
