St Peter's is a small church with aisleless nave and chancel and a W tower with a pyramid roof. The nave has 12thc. N and S doorways, the S under a porch dating from 1868, when the nave was rebuilt. The chancel is 13thc. and the tower 14thc. Construction is of stone and pebble rubble. The nave has recently been converted into a church hall by screening it from the chancel and laying a tiled floor. Benches for the parishioners have been installed in the chancel, which already contained choir stalls and the organ. The nave doorways are described below, but the glory of the church is a 12thc relief of St Peter now set into the interior N chancel wall.

In 1086 the manor of 3½ hides was held by the Abbot of Ely.

Pevsner strangely describes the relief as a "standing Norman figure of a priest with a book and an aspersorium(?)", although both the key and the inscription are visible in his illustration (12a).
