Reasons for Designation
Entrance graves are funerary and ritual monuments dating to the later Neolithic, Early and Middle Bronze Age (c.2500-1000 BC). They were constructed with a roughly circular mound of heaped rubble and earth, up to 25m in diameter, the perimeter of which was often defined by a kerb. The mound contains a rectangular chamber roofed by slabs. The chamber was accessible via a gap in the mound's outer edge and often extends back beyond the centre of the mound. Excavations have revealed cremated human bone and funerary urns, usually within the chambers but on occasion within the mound. Some chambers have also produced ritual deposits of domestic midden debris, including dark earth typical of the surface soil found in settlements, animal bone and artefact fragments. In England, entrance graves are confined to the extreme south west, with 93 recorded surviving examples located on the Isles of Scilly and in Penwith peninsula at the western tip of Cornwall.
Kerbed cairns are prehistoric funerary monuments dating to the Bronze Age (c.2000-700 BC). They were constructed as rubble mounds, defined by an outer kerb and often containing stone lined rectangular boxes or cists covered with a capstone. Predominant in upland areas and often in prominent locations they are representative of their period.
Despite partial early excavation and modification through later periods of re-use, the entrance grave re-used as a kerbed cairn with cist known as Chapel Carn Brea will contain archaeological and environmental information relating to its construction, re-use, ritual, funerary and religious practices, social, territorial and strategic importance through time and its overall landscape context.
Details
The monument includes an entrance grave with subsequent kerbed cairn and cist, situated at the summit of Carn Brea, the most westerly hill in mainland Britain. The monument survives as a slightly oval stony mound measuring up to 29m long by 23m wide and 2.8m high, with a visible cist and large in-situ capstone to the south. A shelter with drystone walling, thought to utilise some of the kerbing from the cairn, represent the remains of a Second World War radar station.
The name derives from the medieval re-use of the cairn as the base for a hermit's chapel called St Michael of Brea. The chapel was first recorded in 1302 following the murder of the hermit who had been responsible for maintaining a beacon for the fishermen of the parish of St Just. The chapel itself was destroyed in the early-19th century. Hals (died 1737) was the first to mention the cairn and chapel. Borlase drew the chapel in its original state in 1750, and it was also recorded by Swete in 1778 and Tremenheere in 1800.
