The Architectural Background of the Ely Octagon

Abstract

Ely octagon is usually regarded as an original invention of the architect Alan of Walsingham. However, the ground plan of the Norman church, with both eastern and western transepts and two axial towers, has affinities with the plans of some Romanesque churches in the Rhineland which also possess octagonal central towers. The presence of an octagonal Norman tower at nearby Swaffham Prior, a church which has belonged to Ely since before the Norman Conquest, suggests that the Norman church at Ely may also have had an octagonal central tower.
