Ely
The name Ely is believed to come from the situation of the city on a small hill in the flat fenland that would have been an island when water levels where higher in the past. Due to the abundance of eels in the local area the it was known as the Island of Eels.
Eely was the last stronghold of the Anglo-Saxons and Hereward the Wake in 1071 during the Norman invasion.
