The main entrance to the Palace quarter was the Chalke (Bronze) gate at the Augustaion. The Augustaion was located on the south side of the Hagia Sophia, and it was there that the city's main street, the Mese ("Middle Street"), began. To the east of the square lay the Senate house or Palace of Magnaura, where the University was later housed, and to the west the Milion (the mile marker, from which all distances were measured), and the old Baths of Zeuxippus.
