The masonry of the south wall of the aisle formed part of the 1199 Church. The three windows east of the south door and the west window are all perpendicular insertions carried out, presumably, when the roof was raised in the C15, but the glass is modern.
Just inside the south door is a holy water stoup for those entering the Church to make a sign of the Cross; and there is a piscina which was associated with the medieval Chantry of All Saints which was accommodated here.
