The Aqua Augusta or Serino Aqueduct was one of the largest, most complex and costliest aqueduct systems in the Roman world; it supplied water to at least eight ancient cities in the Bay of Naples including Pompeii and Herculaneum.[1] This aqueduct was unlike any other of its time, being a regional network rather than being focussed on one urban centre.[2]

Route of the Aqueduct[edit]

The route of the aqueduct is well known thanks to the writings of two Italian engineers[3] who were asked to see if it could be brought back in use as the main water supply of Naples in the 16 and 19th centuries.

There were ten branches, seven of which were for cities while three were for some of the numerous luxurious villas in this area popular with rich Romans, such as the Villa Pollii at Posillipo.[4] Including the branches, the total length of the aqueduct was approximately 140 km, making it the longest Roman aqueduct, with the possible exception of the Gadara Aqueduct, until the 5th century AD when the Valens Aqueduct was extended in Constantinople. The Aqua Augusta was one of the most difficult and costly aqueducts ever constructed by an ancient civilisation.[5] Despite its size and complexity, the Augusta is today largely unknown as a major monument.

The aqueduct's source, the Fons Augusteus (now known as Acquaro-Pelosi), was in the Terminio-Tuoro mountains near the modern town of Serino not far from the city of Avellino and at 376 metres above sea level. One of its main terminations was the enormous Piscina Mirabilis at the naval base and port of Misenum.

Since the aqueduct traversed such a distance, many difficulties were encountered when building it; 2 km long tunnels were cut through mountains, there was ground movement near the coast due to volcanoes and a sea crossing was needed to the island of Nisida.

There is evidence that a large number of private users were members of the Rome senatorial class. In Rome, a letter from the emperor was required to gain a private connection and so it seems that imperial favour was also a factor in accessing the Augusta’s water.


History[edit]

The Emperor Augustus (or more likely his close friend and ally Agrippa) built the Aqua Augusta between 30 and 20 BC.[6]

During the war with Pompeius, Augustus ordered the construction of the Portus Julius harbour complex just west of Puteoli. Later, this harbour was seen as less ideal for the navy because of silting problems and a new major naval base was built further west at Misenum, where two lakes were connected to become the basis of the western Mediterranean war fleet. Large quantities of fresh water were needed for the base itself and for the ships, which must have been one of the reasons why Augustus had the new aqueduct built.[7] The main cistern filled by the aqueduct is the Piscina Mirabilis in Ba ́coli (Misenum).

Such a major monument required constant maintenance; there were major repairs in the Flavian period (1st century AD) with the addition of parallel tunnels and the Emperor Constantine also engaged in a massive restoration documented on an inscription tablet[8] discovered in Serino and dated to AD 324. The destinations listed are:

The cities of Pompeii, Herculaneum and Stabiae were also originally supplied by the aqueduct but being destroyed and covered by the eruption of Vesuvius in 79 AD they did not appear on this list.

The next major eruption in 472 AD left the aqueduct covered in ash and 3.5 km of the duct collapsed because of this. This cut off the supply of water to all the towns except Nola and Acerrae. The poor administrative and economic situation in Campania at this time, and Italy in general, prevented major repairs to the Augusta. Written references to aqueducts in Naples after this time only refer to other aqueducts that were now in the area.

In modern times, parts of the aqueduct, in addition to the Piscina Mirabilis were vital to the region's survival during World War II. Many locals used the areas as air-raid shelters.

Visible Remains[edit]

There are few visible remains of the aqueduct today, although much of it still exists below ground. Traces of the original structure may be found at a number of sites in and around Naples such as the two parallel Ponti Rossi aqueduct bridges and the well-preserved Piscina Mirabilis at Misenum. This is one of the largest such terminal reservoirs on an aqueduct known in the Roman Empire and survives almost intact to this day. It was probably intended as a strategic water resource for the naval base, especially if the base had been besieged.

Literary allusions[edit]

It features prominently in the novel Pompeii by Robert Harris, whose protagonist is a water engineer ("Aquarius") sent from Rome to maintain the aqueduct in AD 79 during the time around the eruption of Mount Vesuvius.
