Esquiline Hill
On the top of the Esquiline Hill Gallienus planned to erect a colossal statue depicting himself in the guise of the invincible Sun God, but the work was never completed. The "arcus Gallieni" (Arch of Gallienus) still stands at the Esquiline gate. The "Palatium Licinianum" (palace) stood near the site of the present church of Santa Balbina.
