Cambridge, historic county of Cambridgeshire, England. The city lies immediately south of the Fens country (a flat alluvial region only slightly above sea level) and is itself only 20 to 80 feet (6 to 24 metres) above sea level. Most of the city is built on the east bank of the River Cam, a tributary of the Ouse. Suburbs extend across the river, but modern development to the west has been largely restricted to university expansion.
Originally a fording place, Cambridge possesses earthworks, including Castle Hill, and Roman remains. Later there was another settlement at Market Hill. Two monastic foundations date from the 11th and 12th centuries, respectively—Barnwell Priory and a Benedictine nunnery, replaced in 1496 by Jesus College.
Cambridge received its first charter in 1207; the uninterrupted existence of public officers in the city since the Middle Ages is noteworthy. It also has an interesting guild history, Corpus Christi College having been founded by guilds in 1352
