The Cathedral Church of the Holy and Undivided Trinity is known as the "Ship of the Fens", a name inspired by the distant views of its towers that dominate the low-lying wetlands called The Fens.
The diocese of Ely was created in 1108 out of the see of Lincoln, and a year later the bishopric of Ely was founded.
The cathedral was started by William I in 1083, suffered the collapse in 1322 of the main tower, which was rebuilt as an octagon, and was completed in 1351.
