The church comprises a W tower, mainly of 14th-15thc. date but with the tower arch responds retaining water-holding bases, and a 13thc. nave and chancel. The font could be partly Romanesque.

The manor of Somerville-Aston was named after Roger, grandson of Sir Gualter de Somerville from Somerville, near Evreux in Normandy, who had helped with the Conquest. It was transferred to Worcestershire from Gloucestershire in 1931.

The inventive style of the font resembles nothing else in the county, and its date is uncertain. Pevsner questions whether it is a Romanesque font that has been cut down and retooled; local opinion considers it to be post-Reformation. There is a unity in the detail of bowl, stem and base; they could perhaps be made of the same stone.
