From the Augustaeum led a great street, the Mese, lined with colonnades. As it descended the First Hill of the city and climbed the Second Hill, it passed on the left the Praetorium or law-court. Then it passed through the oval Forum of Constantine where there was a second Senate-house and a high column with a statue of Constantine himself in the guise of Helios, crowned with a halo of seven rays and looking toward the rising sun. From there, the Mese passed on and through the Forum Tauri and then the Forum Bovis, and finally up the Seventh Hill (or Xerolophus) and through to the Golden Gate in the Constantinian Wall. After the construction of the Theodosian Walls in the early 5th century, it was extended to the new Golden Gate, reaching a total length of seven Roman miles. After the construction of the Theodosian Walls, Constantinople consisted of an area approximately the size of Old Rome within the Aurelian walls, or some 1,400 ha.
