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. Within the landscape of Bodmin Moor are many discrete plots of land enclosed by stone walls or banks of stone and earth, most of which date to the Bronze Age (c.2000-700 BC), though earlier and later examples also exist. They were constructed as stock pens or as protected areas for crop growing and were sometimes subdivided to accommodate animal shelters and hut circle settlements for farmers or herders. The size and form of enclosures may therefore vary considerably, depending on their particular function. Their variation in form, longevity and relationship to other monument classes provides important information on the diversity of social organisation and farming practices among prehistoric communities. They are highly representative of their period and a substantial proportion of surviving examples are worthy of protection.

This enclosure on Tregarrick Tor has survived well, displaying several original internal features, and has suffered no evident disturbance. The monument will also preserve contemporary deposits and land surfaces beneath the hill-wash against its northern and southern walls. Its proximity to broadly contemporary hut circles and field systems on Tregarrick Tor demonstrates well the nature of land use during the Bronze Age.

The monument comprises a sub-rectangular enclosure situated near Prehistoric hut circles and field systems on the southern slope of Tregarrick Tor on SE Bodmin Moor. The enclosure survives with a boulder and rubble wall, up to 2m wide and 0.7m high, enclosing an internal area of 0.65 hectares and measuring 28m ENE-WSW by 23m NNW-SSE. The wall contains occasional edge-set slabs along both its inner and outer faces. The enclosure is almost square in shape, but extends further to the west at its NW corner. The wall angle at that corner bounds the north and west sides of a levelled, turf-covered platform, 4m diameter and 0.3m high at its downslope edge, typical of the stances on which Prehistoric wooden houses were constructed. A 6m diameter concentration of boulders cleared from the enclosure's interior is situated against the northern wall's inner face and centred 9m west of the NE corner. Soil washed down the hill-slope has built up against, and partly masked, the northern sides of the enclosure's northern and southern walls.

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.
