The medieval church comprised a short, unaisled nave with a chancel, S porch and small W tower.
The tower was early C12, and early engravings show it with an embattled parapet and a small spike, the latter removed before the early C19.
The nave had large, perpendicular windows, and the chancel was apparently brick, with square-headed windows, and was probably built in the C16.
N and S transepts were added in 1837, when the medieval chancel arch was removed.
The medieval tower was repaired in 1856, and its top stage and parapet were removed in 1871.
