Berkshire Downs

The Berkshire Downs are a range of chalk downland hills in southern England, part of the North Wessex Downs Area of Outstanding Natural Beauty. The Berkshire Downs are wholly within the traditional county of Berkshire, although split between the current ceremonial counties of Berkshire and Oxfordshire. The western parts of the downs are also known as the Lambourn Downs.

The Berkshire Downs run east–west, with their scarp slope facing north into the Vale of White Horse and their dip slope bounded by the course of the River Kennet. Geologically they are continuous with the Marlborough Downs to the west and the Chilterns to the east. In the east they are divided from the Chilterns by Goring Gap on the River Thames. In the west their boundary is generally taken to be the border between Berkshire and Wiltshire, although the downs in Wiltshire between the Berkshire border and the valley of the River Og are sometimes considered to be part of the Berkshire Downs.

English downland has attracted human habitation since prehistoric times. The ancient track known as the Ridgeway runs along the Berkshire Downs. Prehistoric sites in the Downs include Wayland's Smithy (Neolithic), numerous tumuli (Neolithic or Bronze Age), Uffington White Horse (Bronze Age), Liddington Castle and Uffington Castle (Bronze Age and Iron Age), and Segsbury Camp and Grim's Ditch (Iron Age).
