Image of the feature "Other: Central dome" at Cambridge.

An eight-part ribbed vault with square section ribs carried on capitals at the level of the top of the drum. These capitals are supported by attached round shafts on corbels immediately above the imposts of the main gallery pier capitals. The corbels, in the form of human heads, are clearly 19thc. and are not described, but all appear in photographs. The upper capitals, which have no impost blocks, are more convincingly 12thc. and are described below. Ribs are numbered to correspond with the gallery and nave arcade piers immediately below them.
