The north wall of the nave is Saxon: the pillars and south aisle were added during the 14th century. The huge tie-beam where the nave and chancel join is the rood beam, which once would have supported a rood cross. The cross would have been removed during the reformation, and a tympanum of lath and plaster now fills the gap. The painting is of the Royal Arms of King James I who ruled from 1603 - 1625. The painting extends above the current ceiling level: the ceilings were plastered during the 18th century. At some point the painting was limewashed out and the tympanum appeared bare. The arms were rediscovered and conserved in 1986.
