The red sandstone church has an aisled nave, a chancel, a W tower and a S porch entrance. The chancel was rebuilt in 1754, the N aisle and arcade were added by Rickman in 1826, and the church was largely rebuilt in 1858-65. Fragments of Romanesque voussoirs have been reused as corbels beneath the guttering of the modern porch, and in 1984 a carved stone panel was found under the plaster of the E wall of the S nave aisle.

Godric, a thegn of Edward the Confessor, held the manor before the Conquest. At DS it was held by William Fitz Ansculf; there was a priest at Hagley at this time. The manor was later a knight's fee of the barony of Dudley.

The voussoirs resemble those of the S doorway of St Kenelm's, Romsley. Some aspects of the surface carving of the panel can be compared with the tympanum at Pedmore and the fragment set in the porch at Chaddesley Corbett, but the heavily cut foliation is not found at either of these sites. The trefoil tail terminal has a generic resemblance to that on the tympanum of Moreton Valence, Gloucestershire. From a photograph, Professor G. Zarnecki dated the panel to the years 1100-20 (verbal communication).
