Via Sublacensis

The Via Sublacensis was a Roman road constructed to connect Nero's palace (the "Villa Sublacensis") in present-day Subiaco to Rome, splitting off from the Via Valeria near Varia (modern Vicovaro), about 10 km northeast of Tivoli.
It is most commonly referred to as the origin of the Aqua Anio Novus, a major aqueduct whose head was originally at the 38th milestone of the Via Sublacensis.
