The church of All Saints consists of a chancel with north vestry and a north chapel, a nave with a north aisle and a west tower.
The 12th century church had a narrow chancel and nave, of which the east wall was about 12 ft. and the west wall was about 6 ft. westward of those of the present nave. The east end of the chancel was a few feet eastwards of the present chancel arch. In about 1180, a narrow north aisle was added, and some 40 years later, it was extended eastwards for the full length of the chancel, the chancel arch being entirely removed in the process. During the 14th century, the south wall of the nave was rebuilt and the present south porch built. In the latter part of that century, the chancel was lengthened eastwards, a vestry was built on the north side, and the aisle was widened and lengthened eastwards to join the vestry, one bay being added to the nave.
The west tower was then built, partly within the lines of the west end of the nave but taking up half the western bay; presumably, the churchyard boundaries did not then allow it being built clear of the west end of the church. In the 15th century, the chancel arch was built again, a clearstory added to the nave, and some windows put in the north aisle. The south wall of the nave and the clearstory were rebuilt in the 19th century.
