St Peter's has a three-bay aisled and clerestoreyed nave with late medieval arcades whose capitals are ornamented with heads and shields. The chancel is also elaborate, with 13thc. blind arcading on the side walls. The arch of a N chapel cuts into the arcading, but the chapel itself was replaced by a vestry in 1869. W is a tall Perpendicular tower of three storeys. The late-12thc. N and S doorways remain: the S more elaborate and protected by a porch. Construction is of grey limestone in rough little blocks, with larger blocks of ironstone used as quoins and facings, more liberally on the tower than elsewhere.

In 1086 Cogenhoe comprised just one hide and 2½ virgates of land of which three were held by Countess Judith and 3½ by Guy de Raimbeaucourt. No church is mentioned in either holding.

Benefice of Cogenhoe and Great Houghton and Little Houghton with Brafield-on-the-Green.
