The medieval church, demolished in 1859, comprised chancel, nave with north chapel and south porch, and the surviving west tower. The later 12th-century chancel arch, which survived until 1859, confirms the evidence of the surviving 12th-century font for a 12th-century church, comprising nave and chancel. That church was enlarged in the earlier 14th century when the north chapel was added, the nave was probably extended westwards, and the west tower was built. The church was remodelled in the later 15th century, the chancel being rebuilt by Merton College in 1482. All the windows except the belfry windows were replaced, the nave was reroofed, and a plain south porch built; the west doorway, west window, and tower arch are probably of the later 16th century. A 15th- century rood screen and an early 16th-century pulpit survived in the church until 1859 although the screen was removed from the chancel arch to the north chapel between 1846 and 1857.
