Aquaeductus Kyrenaike

The Aquaeductus Kyrenaike was an aqueduct located in Kyrenaika.

History
When Kyrenaika became a Roman province in the 1st century BCE, they commissioned the construction of the aqueduct in green mountain region, overseered by the Roman engineer Vitruvius.

By time of Bayek's visit in 47 BCE, it was under construction. A number of bandits who resided in the mountains attempted to sabotage the construction, leading Vitruvius to send Bayek and eliminate the bandits.
