Tyrrhenian sea: Underwater Roman city Portus Julius orthomosaic overfly Orthomosaic Recostruction by UAV (Unmammed Aerial Vehicles) Surveyed approximately 0,05 square marine miles (15 hectares) Portus Julius (Julius Porto in honor of Gaius Julius Caesar Octavianus), was, since the first century BC (37 BC) to the fourth century, a port suburb of the Roman city of Puteoli. Built on the Neapolitan coast at Lake Lucrino, it was an impressive port complex extended up to Lake Averno. Spared the destruction wrought on site of the eruption of Monte Nuovo volcano in 1538 the formed close to the north, now the plants are submerged due to the bradyseism, and were rediscovered only in 1956. The port was built in 37 BC by Agrippa at the behest of Emperor Octaviano 'doing penetrate the sea in Lucrino and Averno "and, initially lakes, he played the naval military base function during the civil war against Sextus Pompey which would end the Roman Republic. According to the descriptions of Cassius Dione and Velleius Paterculus, the coastal port offering a natural refuge protected by warships as well as a large inner yard. Large engineering works connected it, in fact, both the Lake Lucrino, which was much larger at the time and acted already sheltered bay, is the lake of Averno which provided a safe harbor and, thanks to the nearby woods, even the timber for the shipyard. Under the COCCEIUS AUCTUS director, the artificial canal, existing and 300 meters long that linked the two lakes, was widened to 50 meters. Was also set up at the port, an outlet for the lake Lucrino digging the short sandy stretch that separated him from the sea. Portus Julius had a costal pier 400 meters long and built on arches that rested on fifteen square piers. He was defended by a long dam - on which passed the Via Herculea (or Via Herculanea) - who started from Punta dell'Epitaffio , and finally to Punta Caruso, and that included the entrance to the waterway leading to Lucrino Lake . The military complex was completed by underground walkways (see Cave Cocceio) commissioned by Agrippa to put in secure communication Lake Averno with the port of Cumae, as described by Strabone in his Geography. The military function of the port ran out about twenty years after the construction due to the low depth of the lake Lucrino and the partial silting up with the consequent transfer of the fleet at Misenum in 12 BC Portus Julius maintained, however, for a long time (until the fourth century) the commercial port function. In the Augustan age the port settlement prospered greatly extending towards Puteoli with the construction of two new suburbs (vici) citizens: the Vicus Lartidianus and the Vicus Annianus. Under Nerone it was undertaken the construction of a long navigable canal (fossa Neronis, partially detected from aerial photographs) that would have to join Portus Iulius in Rome, to allow safe traffic by storms for vessels that supplied grain to the capital. The construction of the canal was cut to the death of Nerone, and was never completed. Portus Julius was abandoned in the fourth century for the progressive lowering of the coastline caused by bradisismo. At the end of the fifth century, according to Cassiodorus, the coastal dam had already collapsed and part of the same stone material was reused to repair the walls of Rome. In the following centuries the retreat of the sea coast produced the disappearance of Lake Lucrino and the Roman port was completely submerged. The complex has been recognized directly only the eastern part. There you can see the route of a road that passes through the remains of two parallel rows of port warehouses, with raised reticulate masonry, plaster, wooden formwork, plumbing and then a larger building with a different orientation from all other structures, obliquely, in which it was decided to recognize the admiral's domus there being still the mosaic floors.
