The dominating feature to your north is the Callixtus Hall.  The small
roofed building supported by a number of doric columns, appears to be a
resting area for the palace residents.  The channeled roof provides little
shade for the individuals walking under it.  The thick palace walls are to
your south, and you can see that the atrium path continues east and west.
