The southern outer apse.
The outer apses are virtually symmetrical,
and the southern apse is as featureless
as the northern. The off-axis entrance doorway is visible to the left, and the
southern
"slab altar" of the inter-apse doorway can be seen far right. The
large flanking slab to
the left of the "slab altar" has a temple carving on the side facing
the camera although
this cannot be made out in this photo.
