St Peter's is substantially a 12thc. church of nave, chancel and W tower. Aisles were added to the nave in the 14thc. The W tower, with its twin bell openings, angle shafts and tower arch are all recorded here, as is the font. Construction is of flint and pebble with ashlar dressings and the tower has a lead spike. There was a restoration by Ewan Christian in 1883.

In 1066 Ulf, a thegn of King Edward, held 4½ hides in Duxford, and Herulf and Ingwar, also Edward's men, had smaller holdings. Another holding of 4¾ hides was divided among 13 sokemen, Eadgifu the Fair held 6 hides and Archbishop Stigand 3½. By 1086 everything had changed. Ulf's holding went to Robert de Tosny and Gilbert held it from him. The holdings of Stigand and Herulf passsed to Count Eustace. Eadgifu's 6 hides went to Count Alan and were held from him by Gerard, and a further 3 hides and 1 virgate were held by Payne from Hardwin de Scales.

St Peter's advowson was later held by the descendants of Hardwin de Scales in what later became known as Bustelers manor.
