Monte di Procida

Lake Fusaro (Italian: Lago di Fusaro, Latin: Acherusia Palus, Ancient Greek: Ἀχερουσία λίμνη, romanized: Acherousia limne) is a lake situated in the province of Naples, Italy, in the territory of the community of Bacoli. It is about 0.5 miles (800 m) from Baia, and about 1 mile (1.6 km) from the acropolis of Cumae. It is separated from the sea by a narrow coastal strip. It is a very unusual ecosystem of great interest, characterized by a variety of vegetation specific to the region.

The Piscina Mirabilis (Latin for "wondrous pool") is an Ancient Roman cistern on the Bacoli hill at the western end of the Gulf of Naples, southern Italy. It ranks as one of the largest ancient cisterns built by the ancient Romans, compared to the largest Roman reservoir, the Yerebatan Sarayi (aka Basilica Cistern) in Istanbul. The adjective Mirabilis was given by the 14th c. Tuscan poet Francesco Petrarca on one of his visits.

The Aqua Augusta, or Serino Aqueduct (Italian: Acquedotto romano del Serino), 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. This aqueduct was unlike any other of its time, being a regional network rather than being focused on one urban centre.

Bacoli (Italian pronunciation: [ˈbaːkoli]; Latin: Bauli) is a comune (municipality) in the Metropolitan City of Naples in the Italian region Campania, located about 15 kilometres (9.3 mi) west of Naples.

Fortino Tenaglia Lighthouse (Italian: Faro di Fortino Tenaglia) is an active lighthouse located on a promontory on the west side of the Gulf of Pozzuoli in the municipality of Bacoli, Campania on the Tyrrhenian Sea.

Miseno is one of the frazioni of the municipality of Bacoli in the Italian Province of Naples. Known in ancient Roman times as Misenum, it is the site of a great Roman port.

Pennata is a wreck of the crater of Lake Miseno; it is part of the comune of Bacoli. It has been considered a small island since November 4, 1966 (the same day as the flood in Florence), when, following a violent sea storm, the strip of sand that connected it to the mainland disappeared. It is made up of yellow tuff and the very rich vegetation and the remains of brick structures show that it was a densely populated area.

Lucrinus Lacus or Lucrine Lake (Italian: Lago di Lucrino; Neapolitan: Laco 'e Lucrine) is a lake in Campania, southern Italy. It is less than one kilometre to the south of Lake Avernus and is separated from the Gulf of Pozzuoli by a narrow strip of land. Also known as the maricello ("little sea"), the size of present-day Lago Lucrino was significantly reduced by the rise of the volcanic cone of Monte Nuovo in 1538. The lake's modern dimensions are 1.5 kilometres (0.93 mi) long and about 5 metres (16 ft) deep.The recorded history of Lucrinus Lacus dates back to Sergius Orata, who is credited with creating the first oyster beds there. The lake was also a resort destination for residents of Baiae (cf. Martial i. 62). Its banks were covered with villas, of which the best known was Cicero's villa Cumanum on the east bank, which was the seat of his Academia. The remnants of this villa, and the nearby village of Tripergole, disappeared beneath ejecta from the eruption of Monte Nuovo in 1538. According to a history by Tacitus, Agrippina the Younger was murdered by the emperor Nero's assassins in her villa on the shores of Lucrinus Lacus in AD 59 after escaping an unsuccessful murder attempt while sailing on another craft nearby.The Via Herculanea and a railway traverse the strip of land between the lake and the Gulf of Pozzuoli. The ancient Via Herculanea road ran on a strip of land parallel and further to seaward from the present one and now submerged, which Strabo credited to Heracles with constructing. This strip was reinforced with a sea wall and then opened by Marcus Vipsanius Agrippa to make a harbour of Lucrinus Lacus. He then joined Lucrinis Lacus to Lago d'Averno by a canal, as recorded in Virgil's Georgics, providing a sheltered harbour known as Portus Julius for the Roman western fleet, invisible from the sea.Today Lucrino is a frazione of the comune of Pozzuoli.

Punta Pioppeto Lighthouse (Italian: Faro di Punta Pioppeto) is an active lighthouse located on the northernmost promontory of Procida, Campania on the Tyrrhenian Sea.

Capo Miseno Lighthouse (Italian: Faro di Capo Miseno) is an active lighthouse located at the end of the promontory, with the same name, that marks the north-western limit of the Gulf of Naples as well as the Gulf of Pozzuoli toward the Tyrrhenian Sea in the province of Naples.

The Grotta di Cocceio (Cocceius' Tunnel) is an ancient Roman tunnel nearly a kilometre in length connecting Lake Avernus with Cumae and dating from 38-36 BC. It was burrowed through the tuff stone of Monte Grillo by the architect Lucius Cocceius Auctus at the command of Agrippa who was in the process of converting the Lake into a military port, the Portus Julius.The tunnel was wide enough to allow the passage of two wagons. The Avernus side of the passage was decorated with a colonnade and had many statues in niches hewn into the tuff walls of the entrance. Light and air were provided by six vertical shafts dug into the hill (the longest of which was over thirty metres high) The Aqua Augusta aqueduct supplying the port was dug in a tunnel parallel to and on the northern side the road and was also equipped with niches and vertical shafts. The Crypta Romana tunnel was also built nearby from Cumae to its port in the same period, as well as other tunnels in the vicinity (e.g. the Crypta Neapolitana). With the end of the civil war between Octavian and Mark Antony in 31 BC and the displacement of the fleet from Portus Julius to the port of Misenum in 12 BC, the tunnels lost their strategic interest, but continued to be useful for practical and commercial reasons. The tunnel is also known as the Grotta della Pace, in reference to a Spanish captain, Pietro de Pace, who made use of the tunnel in 1508–1509 to plunder the ruins of Cumae, which, at the time, still bore many rich items. The Grotta was heavily damaged during World War II and is no longer open to the public. It has undergone extensive restoration works in recent years (up to 2017) and should be reopened in the near future. However, colonies of five species of legally-protected bats were discovered during the restoration, making an environmental assessment necessary before the reopening can go through.

Cape Miseno (Italian: Capo Miseno, Latin: Misenum, Ancient Greek: Μισήνον) is the headland that marks the northwestern limit of the Gulf of Naples as well as the Bay of Pozzuoli in southern Italy. The town of Miseno is located on the north side of the cape. The cape is directly across from the island of Procida and is named for Misenus, a character in Virgil's Aeneid.
