Buckinghamshire (/ˈbʌkɪŋəmʃər, -ʃɪər/, abbreviated Bucks) is a ceremonial county in South East England. It is bordered by Northamptonshire to the north, Bedfordshire to the north-east, Hertfordshire to the east, Greater London to the south-east, Berkshire to the south, and Oxfordshire to the west. The largest settlement is the city of Milton Keynes.

The county has an area of 1,874 km (724 sq mi) and had an estimated population of 884,656 in 2024. Besides Milton Keynes, which is in the north-east, the largest settlements are in the centre and south of the county and include Aylesbury, High Wycombe, and Chesham. For local government purposes the county comprises two unitary authority areas, Buckinghamshire and Milton Keynes. The county historically had slightly different borders, and included the towns of Slough and Eton. It is one of the home counties

The county has an area of 1,263 km (488 sq mi) and a population of 911,403. The population is concentrated in the east, the area closest to Greater London, which includes the county's largest towns: Reading (174,224), Slough (164,793), Bracknell (113,205), and Maidenhead (70,374). The west is rural, and its largest town is Newbury (33,841). For local government purposes Berkshire comprises six unitary authority areas: Bracknell Forest, Reading, Slough, West Berkshire, Windsor and Maidenhead, and Wokingham. The historic county included the parts of Oxfordshire south of the River Thames, which formed its northern border, but excluded Caversham and Slough.

The Grand Union Canal in England is part of the British canal system. It is the principal navigable waterway between London and the Midlands. Starting in London, one arm runs to Leicester and another to Birmingham. The Birmingham canal is 137 miles (220 km) with 166 locks. The Birmingham line has a number of short branches to places including Slough, Aylesbury, Wendover, and Northampton. The Leicester line has two short arms of its own, to Market Harborough and Welford.

It has links with other canals and navigable waterways, including the River Thames, the Regent's Canal, the River Nene and River Soar, the Oxford Canal, the Stratford-upon-Avon Canal, the Digbeth Branch Canal and the Birmingham and Fazeley Canal.

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.

William Herschel's 40-foot telescope, also known as the Great Forty-Foot telescope, was a reflecting telescope constructed between 1785 and 1789 at Observatory House in Slough, England. It used a 48-inch (120 cm) diameter primary mirror with a 40-foot-long (12 m) focal length (hence its name "Forty-Foot"). It was the largest telescope in the world for 50 years. It may have been used to discover Enceladus and Mimas, the 6th and 7th moons of Saturn. It was dismantled in 1840 by Herschel's son John Herschel due to safety concerns; today the original mirror and a 10-foot (3.0 m) section of the tube remain.
