The church dates from around 1000 A.D., or possible a few years earlier, and still retains its tall Anglo-Saxon nave, although this was altered by the Normans. The early church was two storeys high, with round-headed windows on the ground floor, two of which survive, and four round windows on the upper level. Three of the latter survive high in the north wall. These windows were unglazed but in bad weather wooden shutters were used to close the lower ones. The contemporary chancel has gone but when the present chancel was rebuilt in 1878 the remains of walls from a short square-ended chancel was discovered; its floor was about two feet below the present chancel floor. In the north aisle are areas of Saxon plaster above the Saxon window, while a Saxon string course runs along the wall, just below the roof of the aisle and above the tops of the later pointed arches. A piece of a late Saxon cross-shaft has been built into the wall at the north-west corner of the church, near the tower.
