All is revealed. The
nave is romanesque - and how - the pillars are probably re-used roman ones
from local sites (the reddish patches on the arches of the arcade are
powdered roman tile). The crossing is romanesque up to the capitals, 14th
century above - as is the screen in the middle distance.
You've probably noticed the fresco on the north of the nave wall, but don't
miss the one over the crossing arch - that one's somewhat later (13th
century) and, uniquely in the UK, shows the Virgin interceding with Christ
with bare breasts...
