The city of Cambridge is a university town and the administrative centre of the county of Cambridgeshire, England. It lies in East Anglia about 50 miles (80 km) north-by-east of London. Cambridge is at the heart of the high-technology centre known as Silicon Fen – a play on Silicon Valley and the fens surrounding the city. Cambridge is well known as the home of the University of Cambridge. The university includes the renowned Cavendish Laboratory, King’s College Chapel, and the Cambridge University Library. The Cambridge skyline is dominated by the last two buildings, along with the chimney of Addenbrooke’s Hospital in the far south of the city and St John’s College Chapel tower in the north. According to the United Kingdom Census 2001, the city’s population was 108,863 (including 22,153 students), and the population of the urban area (which includes parts of the neighbouring South Cambridgeshire district) is estimated to be 130,000.
From the 1930s to the 1980s the size of the city was greatly increased by several large council estates planned to hold London overspill. The biggest impact has been on the area north of the river, which are now the estates of Arbury, East Chesterton and King’s Hedges, and there are many smaller estates to the south of the city. In 1962 Cambridge’s first shopping arcade, Bradwell’s Court, opened on Drummer Street, though this was demolished in 2006. Other shopping arcades followed at Lion Yard, which housed a relocated Central Library for the city, and the Grafton Centre which replaced Victorian housing stock which had fallen into disrepair in the Kite area of the city. Both of these projects met strong opposition at the time.
The city gained its second University in 1992 when Anglia Polytechnic became Anglia Polytechnic University. Renamed Anglia Ruskin University in 2005, the institution has its origins in the Cambridge School of Art opened in 1858 by John Ruskin. The Open University also has a presence in the city, with an office operating on Hills Road.
Despite having a university, Cambridge was not granted its city charter until 1951. Cambridge does not have a cathedral, traditionally a prerequisite for city status, instead falling within the Church of England Diocese of Ely. Many of the buildings in the centre are colleges affiliated to the University of Cambridge, including King’s College and Magdalene College. Colleges such as Trinity College and St John’s College own significant land both in Cambridge and outside: Trinity is the landlord for the Cambridge Science Park, and also the port of Felixstowe; St John’s is the landlord of St John’s Innovation Centre next door to the Science Park, and many other buildings in the city centre.
Cambridge and its surrounds are sometimes referred to as Silicon Fen, an allusion to Silicon Valley, because of the density of high-tech businesses and technology incubators that have developed on science parks around the city. Many of these parks and buildings are owned or leased by university colleges, and the companies often have been spun out of the university.
