Charlton had a parish church by the 11th century. The present Church of England parish church of Saint Mary the Virgin was a 13th-century Early English Gothic building but there were substantial Decorated Gothic alterations in the 14th century. The east window is slightly later, in the transitional style from Decorated to Perpendicular Gothic. Around the beginning of the 16th century the clerestory and a new roof were added to the nave, and a new window was added to the south aisle.
