Ely Cathedral is known for its central Octagon, built after the cathedral’s Norman tower collapsed in 1322.
The collapse destroyed the crossing tower but created an opportunity for an unusually ambitious medieval solution. Architect Alan of Walsingham designed a broad octagonal lantern, supported by timber rather than ordinary stone vaulting. Its windows flood the crossing with light and make the interior one of England’s most distinctive medieval spaces.
The present cathedral grew from an Anglo-Saxon religious foundation and a Benedictine monastery. The Norman nave survives as a powerful example of Romanesque architecture, while later additions show the transition into English Gothic design.
Ely’s isolated setting on what was once an island led the cathedral to acquire the nickname “the Ship of the Fens.” The nickname refers to its appearance rising above the flat fenland landscape, not to a nautical function.
