A county in the East Midlands of England, with county town at Cambridge. It is largely flat and agricultural, with much fenland. The main towns of the present-day county are Cambridge, Ely, Wisbech, and Huntingdon.
The main rivers are the Great Ouse, Nene, and Cam. The city of Cambridge of course lies on the River Cam. In the south of the county are hills with the curious name of Gog-Magog.
Several smaller traditional counties have been amalgamated into the modern administrative county: in 1965 Cambridgeshire was officially combined with the Isle of Ely, the fenny country where the Saxon hero Hereward the Wake held out, though they had been a joint county before that. In the 1974 reorganization of the English counties, this joint country was united with Huntingdonshire and the Soke of Peterborough, another 1965 union. Subsequently the town of Peterborough has become an independent borough.
