🧿 Aqua Alsietina

The Aqua Alsietina is an ancient Roman aqueduct, erected sometime around 2 BC during the reign of emperor Augustus, and described in the De aquaeductu of the Roman official Frontinus. Because the aqueduct was constructed under Augustan rule, it was also called Aqua Auqusta. The aqueduct was the earlier of the two western Roman aqueducts, the other being the aqua Traiana. It was the only water supply for the Transtiberine region, on the right bank of the river Tiber until the Aqua Traiana was built.
