Cranborne Chase () is an area of central southern England, straddling the counties Dorset, Hampshire and Wiltshire. It is part of the Cranborne Chase and West Wiltshire Downs Area of Outstanding Natural Beauty (AONB). The area is dominated by, and often considered to be synonymous with, a chalk downland plateau. Part of the English Chalk Formation, it is adjacent to Salisbury Plain and the West Wiltshire Downs in the north, and the Dorset Downs to the south west. The highest point is Win Green Down, in Wiltshire, at . Historically a medieval hunting forest, the area is also noted for its Neolithic and Bronze age archaeology and its rural agricultural character. Definitions As an informally defined region, the boundaries of Cranborne Chase vary depending on usage. When defined as the chalk plateau, it is clearly bounded by escarpments which face the valleys of the Blackmore Vale to the west, the Vale of Wardour to the north, and the Hampshire Avon to the east. To the south the chalk gently slopes, giving way more subtly to the Dorset Heaths landscape around Verwood and Wimborne Minster. The name is derived from its historic use as a medieval hunting forest, which at its height covered an area bounded by Salisbury, Shaftesbury, Blandford Forum, Wimborne Minster and Ringwood, incorporating a slightly larger area than just the chalk plateau. Early written records of this definition include a jury verdict at New Sarum in 1246 and the Quo Warranto of Edward I, issued in or around 1280. Over time this estate shrank, and the term has also been used to describe a smaller remnant area of around by immediately to the west of Cranborne village. A more recent usage of the term, used since 2014 by the Cranborne Chase and West Wiltshire Downs AONB Partnership of local authorities, has been to promote the much larger AONB area simply as "Cranborne Chase AONB". This usage includes a large area outside of the more established landscape and historical definitions of Cranborne Chase, including the West Wiltshire Downs and an area of greensand landscape on the Somerset-Wiltshire border around Longleat and Stourhead. History and archaeology The downland has a long history with many earthworks and archaeology from the Neolithic age onwards. The dense woodland originally covering the downs would have gradually been cleared by the first farmers, but would have grown back repeatedly over the centuries as soils became
