The Aniene (pronounced [aˈnjɛːne]; Latin: Aniō), formerly known as the Teverone, is a 99-kilometer (62 mi) river in Lazio, Italy. It originates in the Apennines at Trevi nel Lazio and flows westward past Subiaco, Vicovaro, and Tivoli to join the Tiber in northern Rome. It formed the principal valley east of ancient Rome and became an important water source as the city's population expanded. The falls at Tivoli were noted for their beauty. Historic bridges across the river include the Ponte Nomentano, Ponte Mammolo, Ponte Salario, and Ponte di San Francesco, all of which were originally fortified with towers.

Anio River in the context of Via Prenestina
The Via Praenestina (modern Italian: Via Prenestina) was an ancient Roman road in central Italy.
Initially called Via Gabiana, from Gabii, the ancient city of Old Latium to which it ran, it received a new name having been extended as far as Praeneste (modern Palestrina). Once past Praeneste the road continued towards the Apennines and the source of the Anio River.
