Cambridge

People were farming here some 3,500 years ago, and an Iron Age settlement stood on Castle Hill from the 1st century BC. The Romans built a small fort, Duroliponte, on the same hill. The Anglo-Saxons called their settlement Grantebrycge, "Granta bridge"; Vikings arrived in 875 and held the town under the Danelaw, and the centre moved from Castle Hill to the Quayside across the river. After the Viking period the Saxons built churches such as St Bene't's, wharves and a mint, and in 1068 William the Conqueror raised a castle on Castle Hill, whose motte survives.

Henry I granted the first town charter between 1120 and 1131. In 1209 scholars fleeing hostility in Oxford founded the university; after the townspeople joined the Peasants' Revolt, a new charter of 1382 handed control of baking, brewing, and weights and measures to the university. In the Civil War Cambridge was headquarters of the Eastern Counties Association, mainstay of the Parliamentarian war effort, and its castle was refortified.

The railway arrived in 1845, after initial resistance, and the town spread into new districts such as Romsey Town; the borough later took in Chesterton, Cherry Hinton and Trumpington. Cambridge escaped relatively lightly from wartime bombing and was made a city in 1951, despite having no cathedral. In the following decades science parks and start-ups grew from the university, creating "Silicon Fen", and the Cambridge Biomedical Campus became one of the largest research clusters of its kind.

The university shapes the city's culture. Its museums range from the Fitzwilliam to the Sedgwick and the Polar Museum, and the college chapels keep a choral tradition known worldwide through the Festival of Nine Lessons and Carols, sung in King's College Chapel each Christmas Eve. Student life brings May Balls, rowing races and the ADC Theatre, where the Footlights comedy troupe stages shows; its members came to dominate British comedy in the 1970s. Science is part of the city's story too: Rutherford's pioneering work in nuclear physics was done here, and in 1953 Francis Crick announced the structure of DNA in the Eagle pub.

Beyond the colleges, the commons and greens host the city's festivals: Strawberry Fair on Midsummer Common on the first Saturday in June, the Midsummer Fair, whose charter dates from 1211, the Cambridge Beer Festival on Jesus Green, the longest-running CAMRA beer festival in the UK, and the Cambridge Folk Festival, held at Cherry Hinton Hall since 1965. The Arts Theatre and the Corn Exchange are the main stages.

Punting — propelling a flat-bottomed boat by pushing a pole against the river bed — is the city's signature pastime, and in summer the river is busy with punts. Cycling is a way of life, and cattle grazing on the commons a few hundred metres from the market square are part of the scene.

At the 2021 census about 145,700 people lived in the City of Cambridge and about 181,000 in the wider built-up area. Students and university staff form a large part of the population in term time, and the city's growth has brought new estates such as Great Kneighton and Trumpington Meadows in the south and developments near the station.

The economy is built on knowledge: research and development, software, high-value engineering, pharmaceuticals and the creative industries, alongside tourism. The Cambridge Biomedical Campus holds AstraZeneca's headquarters and the relocated Royal Papworth Hospital, and technology companies such as Arm and Abcam are based in and around the city. That success has a cost: Centre for Cities named Cambridge the UK's most unequal city in 2017 and 2018.

Daily life moves by bicycle along streets shared with buses and pedestrians, and much of the centre is covered by an air quality management area because of traffic pollution. Residents live in districts such as Chesterton, Romsey, Newnham, Cherry Hinton and Trumpington, while the centre keeps large green spaces such as Jesus Green, Parker's Piece and Midsummer Common.

The city's most famous dish began in a college. Crème brûlée, a rich custard topped with a layer of hardened caramelised sugar, is also known as burnt cream, Cambridge burnt cream or Trinity cream: it was introduced at Trinity College in 1879, with the college arms branded on top of the cream with a hot iron.

Fitzbillies, founded as an independent bakery on Trumpington Street in 1920 and named for its location near the Fitzwilliam Museum, is known for its Chelsea buns; it survived bankruptcies in 1980 and 2011, reopening after a public appeal by the broadcaster Stephen Fry. The market on Market Hill, a trading place since Saxon times, still runs daily stalls in the centre of the city.

Pubs are part of the city's history as much as its eating. The Eagle opened in 1667 as a coaching inn and is remembered for the lunchtime in 1953 when Crick announced the structure of DNA. A walk or punt upriver ends at Grantchester's Orchard Tea Garden, and each spring the Cambridge Beer Festival fills Jesus Green with drinkers.
