A richly designed carpet covers the floor of the hallway.  To your east
you can see an unobstructed view of the retrochoir, used by those seeking
absolution from the royal papal figures.  Engaged columns form the
articulated opening of the arch above, underneath extends this hallway,
running north and south.
