Reasons for Designation
Since 1916 the Porton Down Range has been used for military purposes. As on the Salisbury Plain Training Area, this has meant that it has not been subject to the intensive arable farming seen elsewhere on the Wessex chalk. Porton, as a result, is one of very few surviving areas of uncultivated chalk downland in England and contains a range of well-preserved archaeological sites, many of Neolithic or Bronze Age date. These include long barrows and round barrows, flint mines, and evidence for settlement, land division and agriculture. Bowl barrows, the most numerous form of round barrow, are funerary monuments dating from the Late Neolithic period to the Late Bronze Age, with most examples belonging to the period 2400-1500 BC. They were constructed as earthen or rubble mounds, sometimes ditched, which covered single or multiple burials. They occur either in isolation or grouped as cemeteries and often acted as a focus for burials in later periods. Often superficially similar, although differing widely in size, they exhibit regional variations in form and a diversity of burial practices. There are over 10,000 surviving bowl barrows recorded nationally (many more have already been destroyed), occurring across most of lowland Britain. Often occupying prominent locations, they are a major historic element in the modern landscape and their considerable variation of form and longevity as a monument type provide important information on the diversity of beliefs and social organisation amongst early prehistoric communities. They are particularly representative of their period and a substantial proportion of surviving examples are considered worthy of protection.
The bowl barrow 440m SSW of the southern corner of Moll Harris's Clump, is a well preserved example of its class. Despite some erosion caused by burrowing animals, it exhibits a largely original profile which includes an unusual external bank. The barrow will contain archaeological remains providing information about Bronze Age beliefs, economy and environment.
Details
The monument includes a ditched bowl barrow with an external bank, one of a group of at least seven round barrows which straddles a shallow coombe on Porton Down. The barrow, which lies on a shallow south facing slope, has a mound 15m in diameter and 0.5m high in the centre of which is an area of disturbance, most probably resulting from an unrecorded antiquarian excavation. Surrounding the mound is a ditch 2m wide and 0.2m deep. Immediately beyond the ditch lies a low bank, c.3m wide and a maximum of 0.35m high, both ditch and bank being most clearly visible on the north west and north sides of the barrow.
