7: Kennet Valley Landscape Character

Overview Historic Landscape Character The Kennet Valley forms a distinct topographic unit which cuts through the chalk of the There are few records for prehistoric occupation Marlborough Downs from Avebury in the west to of the Kennet Valley, partially due to later soil the eastern boundary of the District at Chilton formation processes that may have masked such Foliat. The valley is characterised by smooth evidence. It is possible that an early prehistoric valley sides which roll gently down to a narrow settlement existed in the vicinity of Marlborough, strip of flat, floodplain farmland following the with occasional Bronze Age round barrows course of the . Although fairly located along the fringes of the valley in the shallow, the valley form creates a sense of general area. Mildenhall (Cunetio) remains the enclosure which contrasts with the open only confirmed Roman town within the District, downland to the north, and the valley floor has and is centrally located along the Kennet Valley an intimate, pastoral and riparian character. as it passes through the Marlborough Downs. It is situated at the junction of the Bath to Silchester road and Ermine Street, and at the crossing over Geology and Landform the River Kennet.

The modern landscape of the River Kennet valley has resulted from the medieval water meadow system, defined by the distinctive earthworks still present today. This system was also responsible for the deposition of vast quantities of silt within the river valleys, resulting in an artificial profile for the river valleys. The development of Marlborough and other settlements, such as Ramsbury, has also contributed to the landscape of the area, in the same manner that the smaller villages characterise the Avon valley to the south.

Settlement and Buildings Marlborough through Axford, Ramsbury and Chilton Foliat. Settlements are strung out along the valley, from Chilton Foliat in the east, through Ramsbury, Axford, Stitchcombe, Mildenhall, Marlborough, Manton and East and West Kennett to Avebury and the source of the river at Swallowhead Spring in the west.

Development sensitivities

• the whole area has an essentially tranquil, intimate and pastoral character within which only small-scale, sensitively-designed development, associated with existing built form, could be successfully accommodated without adverse landscape impacts; • valley floor pastures and meadows along the River Kennet corridor represent a scarce landscape and ecological resource, making them particularly unsuitable for development; • the open arable landscapes with a weak hedgerow structure along the valley sides are visually exposed and built development is likely to intrude upon the river corridor landscape; • areas of woodland or enclosed farmland with an intact hedgerow structure along the valley sides are visually contained. In landscape and visual terms small-scale essential development which must be located in the countryside potentially could be accommodated in such areas, where they did not adversely affect the attractive, rural and unspoilt character of the river corridor;
