Some of the Fens are actually below sea level and, if not continuously drained, would normally be covered in water. Ely Cathedral is known as the Ship of The Fens because, being built on a low hill, it stands above the surrounding land like a ship on a wave.

Cambridgeshire was also the home of Oliver Cromwell

The southern part of the county is mostly chalk downlands including the Gog Magog Hills.
