An earlier church had existed on this site since the late 12th century but nothing remains of this except the font, made from Purbeck marble. It consists of a square bowl standing on a circular base, which has four detached shafts. Two sides of the bowl are ornamented with fleur-de-lis, one has roundheaded arcading, and the fourth a crescent, disk, and spiral. The surface is much decayed and the carving incomplete.
