This small narrow walkway circles the entire church, from up here you can
see the forechoir and nave on the first floor.  To your east is a large
clear window, through it you can see the long peristyle garden and portions
of the marketplace.  A small copper fence about 3 feet high prevents you
from falling over into the central nave on the first floor to your west. 
The walkway continues north and south.
