The Anio Novus Aqueduct, which dates back to 38 BC and to Emperor Caligula, can be best seen near Tivoli, close to Rome.
Part of the aqueduct is not far from Tivoli which is 50 minutes from Rome
Numerous archaeological discoveries of the aqueduct can be observed along the Via Empolitana, which are visible from Tivoli to Ciciliano and pass through Castel Madama. The majestic construction stands as a prominent attraction for cultured tourists with an interest in historical heritage. The majority of the remains are concentrated two kilometres away from the center of Tivoli, in the Ponte degli Arci area. The arch closest to the city represents the most substantial part still standing which extended across the Acqua Marcia Aqueduct to the Fosso degli Arci. Several visible ruins, including two arches that traverse roads attest to the aqueduct's historical significance.
There are various areas from which to admire the ancient construction
A more imposing second arch of the aqueduct was part of another bridge, and is approximately 275 metres long and around 35 metres high, spanning the Aniene river. Additional remnants of the Anio Novus Aqueduct can be admired in Valle Barberini, a small tributary near the Fosso di San Gregorio. Following the left side of the Aniene valley, it ran parallel, at an elevated level, first to the Aqua Claudia conduit, then to the Acqua Marcia, the Mandela and the Anio Vetus.
The ancient conduit entered Rome near the central Porta Maggiore
After Castel Madama, it briefly veered away from the river, only to rejoin it after circumnavigating a couple of hills. Continuing towards Tivoli on viaducts and bridges, some of which still stand, it turned south and circled the Tiburtini Mountains from the west. It then traversed a sizable cistern dating back to the Severan era, where it reconnected with a secondary branch before Tivoli.
