Cambridge, United Kingdom

Cambridge is situated about 55 miles (89 km) north-by-east of London and 95 miles (153 km) east of Birmingham. The city is located in an area of level and relatively low-lying terrain just south of the Fens, which varies between 6 and 24 metres (20 and 79 ft) above sea level. The town was thus historically surrounded by low-lying wetlands that have been drained as the town has expanded.

The underlying geology of Cambridge consists of gault clay and Chalk Marl, known locally as Cambridge Greensand, partly overlaid by terrace gravel. A layer of phosphatic nodules (coprolites) under the marl was mined in the 19th century for fertiliser; this became a major industry in the county, and its profits yielded buildings such as the Corn Exchange, Fulbourn Hospital, and St. John's Chapel until the Quarries Act 1894 and competition from America ended production.

The River Cam flows through the city from the village of Grantchester, to the southwest. It is bordered by water meadows within the city such as Sheep's Green as well as residential development. Like most cities, modern-day Cambridge has many suburbs and areas of high-density housing. The city centre of Cambridge is mostly commercial, historic buildings, and large green areas such as Jesus Green, Parker's Piece and Midsummer Common. Some of the roads in the centre are pedestrianised.

The town's river link to the surrounding agricultural land, and good road connections to London in the south meant Cambridge has historically served as an important regional trading post. King Henry I granted Cambridge a monopoly on river trade, privileging this area of the economy of Cambridge. The town market provided for trade in a wide variety of goods and annual trading fairs such as Stourbridge Fair and Midsummer Fair were visited by merchants from across the country. The river was described in an account of 1748 as being "often so full of [merchant boats] that the navigation thereof is stopped for some time". For example, 2000 firkins of butter were brought up the river every Monday from the agricultural lands to the northeast, particularly Norfolk, to be unloaded in the town for road transportation to London. Changing patterns of retail distribution and the advent of the railways led to a decline in Cambridge's importance as a market town.

Cambridge's main traditional theatre is the Arts Theatre, a venue with 666 seats in the town centre. The theatre often has touring shows, as well as those by local companies. The largest venue in the city to regular hold theatrical performances is the Cambridge Corn Exchange with a capacity of 1,800 standing or 1,200 seated. Housed within the city's 19th century former corn exchange building the venue was used for a variety of additional functions throughout the 20th century including tea parties, motor shows, sports matches and a music venue with temporary stage. The City Council renovated the building in the 1980s, turning it into a full-time arts venue, hosting theatre, dance and music performances.

The newest theatre venue in Cambridge is the 220-seat J2, part of Cambridge Junction in Cambridge Leisure Park. The venue was opened in 2005 and hosts theatre, dance, live music and comedy. The ADC Theatre is managed by the University of Cambridge, and typically has 3 shows a week during term time. It hosts the Cambridge University Footlights Dramatic Club which has produced many notable figures in British comedy. The Mumford Theatre is part of Anglia Ruskin University, and hosts shows by both student and non-student groups. There are also a number of venues within the colleges.

Cambridge's two universities, the collegiate University of Cambridge and the local campus of Anglia Ruskin University, serve around 30,000 students, by some estimates. Cambridge University stated its 2020/21 student population was 24,270, and Anglia Ruskin reports 24,000 students across its two campuses (one of which is outside Cambridge, in Chelmsford) for the same period. ARU now (2019) has additional campuses in London and Peterborough. State provision in the further education sector includes Hills Road Sixth Form College, Long Road Sixth Form College, and Cambridge Regional College. The Open University had a presence in the city between 1979 and 2018.
