Reasons for Designation

The Isles of Scilly, the westernmost of the granite masses of south west England, contain a remarkable abundance and variety of archaeological remains from over 4000 years of human activity. The remote physical setting of the islands, over 40km beyond the mainland in the approaches to the English Channel, has lent a distinctive character to those remains, producing many unusual features important for our broader understanding of the social development of early communities. Throughout the human occupation there has been a gradual submergence of the islands' land area, providing a stimulus to change in the environment and its exploitation. This process has produced evidence for responses to such change against an independent time-scale, promoting integrated studies of archaeological, environmental and linguistic aspects of the islands' settlement. The islands' archaeological remains demonstrate clearly the gradually expanding size and range of contacts of their communities. By the post- medieval period (from AD 1540), the islands occupied a nationally strategic location, resulting in an important concentration of defensive works reflecting the development of fortification methods and technology from the mid 16th to the 20th centuries. An important and unusual range of post- medieval monuments also reflects the islands' position as a formidable hazard for the nation's shipping in the western approaches. The exceptional preservation of the archaeological remains on the islands has long been recognised, producing an unusually full and detailed body of documentation, including several recent surveys. Platform cairns are funerary monuments of Early Bronze Age date (c.2000-1600 BC). They were constructed as low flat-topped mounds of stone rubble, up to 40m in external diameter though usually considerably smaller, covering single or multiple burials. Some examples have other features, including peripheral banks and internal mounds constructed on the platform. A kerb of slabs or edge-set stones sometimes bounds the edge of the platform, and a peripheral bank or mound if present. Platform cairns can occur as isolated monuments, in small groups or in cairn cemeteries. In cemeteries they are normally found alongside cairns of other types. Platform cairns form a significant proportion of the 387 surviving cairns on the Isles of Scilly; this is unusual in comparison with the mainland. All surviving examples on the Isles of Scilly are considered worthy of protection.

This platform cairn on Annet has survived well and will retain good preservation of its features due to its protection from surface erosion by the unusual thick thrift cover. The location of this monument near the highest point on the island and its relationship with the island's broadly contemporary settlement evidence demonstrates well the influence of topography on funerary and ritual activity and the wider organisation of land use among prehistoric communities.

Details

The monument includes a prehistoric kerbed platform cairn situated on the gently domed summit of the northern hill of Annet, a relatively large uninhabited island in the south west of the Isles of Scilly. The platform cairn survives with a circular mound of heaped rubble 7m in diameter and up to 0.75m high. The sides rise to a flattened upper platform, 4.5m in diameter defined by a kerb of six spaced slabs and small boulders, up to 0.4m high, visible around the western half and on the south east of the platform. The kerb slabs project through the thick thrift turf that blankets the cairn and surrounding ground surface; an erosion hollow in that turf near the centre of the cairn reveals the cairn's rubble at a depth of 0.25m below the turf surface, implying that the kerb would originally have formed a more prominent feature before the turf developed. This monument is the only prehistoric funerary cairn recorded on Annet. Beyond it, partial exposures of prehistoric field systems appear through the deep blanket of thrift near the western tip of the island, from 280m to the south west, and on the southern area of the island where they are associated with broadly contemporary settlement sites and middens.
