At the eastern entrance to town, and commanding a fine view over Aosta and the mountains, stands the Arco di Augusto (Arch of Augustus), built in 25 BC to mark Rome's victory over the Celtic Salassi tribe. (The sloping roof was added in 1716 in an attempt to keep rain from seeping between the stones.)
This huge gateway, regally guarding the city, is a remarkable relic from the Roman era. The area between the massive inner and outer walls was used as a small parade ground for the changing of the guard.
