There are three topographical points which indicate the situation of the palace. 1. The staircase which connected it with the Hippodrome or Atmeidan. 2. A small artificial port on the Propontis, from whence there was an easy ascent, by a flight of marble steps, to the gardens of the palace. 3. The Augusteum was a spacious court, one side of which was occupied by the front of the palace, and another by the church of St. Sophia.
