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 Normandy Down has survived substantially intact. Despite the minor damage from antiquaries and stone-robbers, this cairn retains clearly the form and construction of its distinctive original kerbs and chamber, the presence of an inner kerb being unusual. The presence of this monument within a cemetery containing various cairn types, its proximity to a prehistoric field system on Water Rocks Down, and the disposition of this and the other cairn cemeteries on successive downs along the coast are all factors combining to illustrate well the diversity of funerary practices and the organisation of land use during the Bronze Age.

Details

The monument includes a prehistoric kerbed platform cairn with an internal funerary chamber situated towards the eastern side of Normandy Down, on eastern St Mary's in the Isles of Scilly. The platform cairn survives with a circular mound of heaped rubble, 13m in diameter and rising 0.5m to a flattened platform, 10m in diameter. The perimeter of the platform is defined by a kerb of eleven contiguous or closely spaced slabs, up to 1.5m long, 0.9m wide and 0.4m high. Breaks occur in the sequence of kerb slabs over the north east quadrant and in the ESE sector due to relatively recent stone-robbing. Four low slabs within the southern and western sectors of this kerb form disturbed remains of an inner kerb on a line approximately 1.1m within the platform perimeter. Centred slightly east of the platform centre is a slab-built rectangular funerary chamber, its long axis oriented NW-SE. The south east half of the chamber survives intact, its interior measuring 1.4m long, NW-SE, by 1.25m wide and defined along each side and across its south east end by three large edge-set slabs, up to 1.9m long, 1.1m wide and 0.7m high. Spanning this intact end of the chamber is another massive rectangular slab called a capstone, laid flat to rest on the side and end slabs, and measuring 1.8m long by 1.5m wide and 0.4m thick. The open part of the chamber beneath the capstone is 0.6m high, while the upper face of the capstone rises 0.75m high above the cairn's platform. The north western half of the chamber has been affected by an unrecorded antiquarian excavation, resulting in two small irregular hollows, up to 0.3m deep, in the platform surface where the chamber's side slabs would have extended. Some elements of the chamber's north west half are visible. These include a displaced capstone embedded in the surface of the platform, lying across the north west ends of the intact side slabs; a slender slab projecting from beneath the north east tip of this capstone, and an edge-set slab visible in the turf 1.5m north west of the displaced capstone. This monument is located at the eastern end of a linear cairn cemetery containing three other cairns dispersed across the plateau of Normandy Down. The other cairns in this cemetery vary in form and include one entrance grave while the two others also contain large funerary chambers. A broadly contemporary field system extends south from Water Rocks Down, from 150m south west of this monument. Other prehistoric cairn cemeteries are located to the south on the successive coastal downs of Porth Hellick Down and Salakee Down. The surface of the modern metalled track passing immediately north of the cairn is excluded from the scheduling but the ground beneath is included.
