The view east back through the inter-apse portal to the temple entrance.
A prominent "V"
groove" hole can be seen in the edge of the left portal upright, there is
also a pair of
holes in the centre of each stone's face. A close-up shot of the "V"
groove in the face of the northern (left),
slab can be seen here. Similar holes can be seen in
the portal uprights of the temple entrance in the
background, this time the stones have a pair top and bottom.
