The dominating feature to your west is the Callixtus Hall.  Smooth
shafts and different type capitals, bud shaped and bell shaped, form the
columns of the hypostyle structure.  Like the atrium, the avenue is an
equally long rectilinear plan, extending across the exterior portion of the
palace.  Roughly 16 feet wide and composed of carefully cut and regularly
shaped blocks of stone, the pathway allows pedestrian traffic to flow north
and south.  The tall palace walls enclose the east portion of avenue.
