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.
After building the Arcus Neroniani
(by Nero), one of the branches of the Aqua Claudia,
aqueduct could provide all 14 districts with water. Domitius added a branche
too, so the palais of the emperor could also be provided
Per day it distributed 185.000 m3 of water!
