The most important aqueduct of Rome was the Aqua Claudia. Emperor Caligula began constructing and emperor Claudius finished it in 52 aD.

It was approx. 69 km long, most of it was underground. The springs were located in the Anio valley near Agosta. At Capannelle the aqueduct was above ground and intersected the fields near Romavecchia.

Because of its massive arches this aqueduct is one of the most impressive aqueducts of Rome.
Per day it distributed 185.000 m3 of water!
