Lake Martignano
Lake Martignano is a small lake in Lazio, Italy north-north-west of Rome, in an extinct crater or maar.
Administratively its coast is divided amongst the municipalities of Rome, Anguillara Sabazia and Campagnano [di Roma].
Overview
In ancient times Lake Martignano was part of southern Etruria and called Alsietinus Lacus. Augustus drew from it the Aqua Alsietina; the water was hardly fit to drink, and was mainly intended to supply his naumachia at Rome, near San Francesco a Ripa, on the right bank of the Tiber, where some traces of the aqueduct were perhaps found in 1720. The course of the aqueduct, which was mainly subterranean, is practically unknown: Frontinus tells us that it received a branch from Lake Bracciano near Careiae : and an inscription relating to it was found in this district in 1887.There is a lawn beach, lake-side cafes and restaurants, and walking tracks.
