Cambs

Cam and chalk south, Ely rising from the great fenland north.

Cambridgeshire is a county of two powerful landscapes. Around Cambridge, the River Cam crosses firmer chalk and clay country, with the Gog Magog Hills providing modest but noticeable relief. Northwards, the land falls into the immense fenland basin, where drained fields, straight waterways and wide skies lead towards Ely, March and Chatteris.

Cambridge gives the southern county an international identity through its university, but the fen country is equally fundamental. Ely rises conspicuously from the former fen islands, its elevated position made dramatic by the level country surrounding it. Cambridgeshire is best understood as the meeting of university city, river basin and fen: a county whose apparent flatness conceals a landscape profoundly organised by water.

From Cambridge into the Fens

The transition north of Cambridge is one of the county’s defining changes. Firmer ground gives way to increasingly level fenland, shaped over centuries by drainage and embankment. Former islands stand subtly above the surrounding fields, and settlements that once faced wetland now sit amid some of England’s richest arable country.

A county engineered around water

The Cam and Great Ouse systems bind southern and northern Cambridgeshire together, while the Old and New Bedford Rivers form striking artificial lines through the Fens. Drainage changed the appearance and use of the landscape without erasing its underlying logic: rivers, channels and former islands still organise settlement and movement.

Ely and the fen islands

Ely’s importance is inseparable from its setting. What was once an island in the surrounding fen remains perceptibly higher than the country around it, with the cathedral visible across great distances. The wider Isle of Ely is a distinctive historic district within Cambridgeshire rather than a separate geographic county.
