Newbury is a market town in West Berkshire, England, in the valley of the River Kennet. It is 26 miles (42 km) south of Oxford, 25 miles (40 km) north of Winchester, 27 miles (43 km) southeast of Swindon and 20 miles (32 km) west of Reading. It is also where West Berkshire Council is headquartered.
Newbury lies on the edge of the Berkshire Downs, part of the North Wessex Downs Area of outstanding natural beauty, 3 miles (5 km) north of the Hampshire–Berkshire county boundary. In the suburban village of Donnington lies the part-ruined Donnington Castle and the surrounding hills are home to some of the country's most famous racehorse training grounds (centred on nearby Lambourn). To the south is a narrower range of hills including Walbury Hill and a few private landscape gardens and mansions, such as Highclere Castle. The local economy is inter-related to that of the eastern M4 corridor, which has most of its industrial, logistical and research businesses close to Newbury, mostly around Reading, Bracknell, Maidenhead and Slough. Together with the adjoining town of Thatcham, 3 miles (5 km) distant, Newbury forms the principal part of an urban area of approximately 70,000 people.
