Most of it below Sea Level. Now a series of Drains, Sluice Gates and Flood Defences in East Anglia but it was a marsh until the 18th Century when a Dutchman, Cornelius Vermuyden went to England designed and organised the drainage. He met some resistance in the form of mediaeval terrorists who feared for their livelihood in the Fens, catching Eels and harvesting various bits and pieces from the Marshes and making a meagre living. They disrupted much of the construction. The Fens have been dominated by Ely Cathedral known as the 'Ship of the Fens' parts of which dates back to 600AD - kind of old.
There are also legend of a large dog that terrorises folks in the Fens known as Black Shuck. A band called "The Darkness' did a rock song about it a little while back.
It is also the home of a lot of very good fishing and some rather big specimens of Esox Lucius, several have been caught over 30 pounds in weight from drains and rivers you can nearly jump over.
