12 Best Sights in Naples, Italy

Naples was originally named by the Greeks after the Mermaid Parthenope (who slew herself after being rejected by Odysseus, at least in the poet Virgil’s version), so it's only fitting that the city should have established one of Europe's first public aquariums in 1874. Founded by the German scientist Anton Dohrn and housed in a Stile Liberty building designed by Adolf von Hildebrandt, the aquarium quickly became the wonder of Naples for children and art-exhausted adults. At the time—when, not so incidentally, the public imagination was being stirred by Jules Verne’s Captain Nemo and Hans Christian Andersen’s Little Mermaid—technological innovations made it possible to funnel seawater directly from the bay into the aquarium.

Officially named the Stazione Zoologica, the aquarium reopened in 2021 after a major six-year overhaul. Tanks still showcase marine life from the Bay of Naples, as well as tropical fish, but the complex now also includes the Museo Darwin-Dohrn (Da-DoM), a few steps away in the leafy Villa Comunale. The highlight is the skeleton of a sperm whale, which washed up in Ischia in 2018, in a room opening up to the bay. Guided tours are available.

The beautifully restored 17th-century Basilica di Pietrasanta, a Cosimo Fanzago Baroque masterpiece built on the site of the Roman Temple of Diana, hosts regular multimedia exhibitions, but the star attraction here is the underground visit to a section of Naples’s oldest aqueduct. Four tours a day descend 40 meters (131 feet) below the busy Via dei Tribunali to large lavishly illuminated cisterns hewed from excavated tuff two millennia ago, still filled with running water (thanks to a collaboration with the city’s waterworks).

In the courtyard of the 16th-century Palazzo Marigliano is this world-famous hospital for dolls, which has a small museum dedicated to its poignant mission. Doll limbs, eyes and well-cuddled, antique characters of all shapes and descriptions spill from packed shelves. In business since 1895, it's a wonderful place to take kids (and their injured toys) and for anyone who retains a childhood sense of wonder with a penchant for the uncanny.

A leading Naples showpiece created as an expression of Bourbon power and values, the Palazzo Reale dates from 1600. Renovated and redecorated by successive rulers and once lorded over by dim-witted Ferdinand IV who liked to shoot his hunting guns at the birds in his tapestries, it is filled with salons designed in the most lavish 18th-century Neapolitan style.

The Spanish viceroys originally commissioned the palace, ordering the Swiss architect Domenico Fontana to build a suitable new residence for King Philip III, should he ever visit Naples. He died in 1621 before ever doing so. The palace saw its greatest moment of splendor in the 18th century, when Charles III of Bourbon became the first permanent resident. The flamboyant Naples-born architect Luigi Vanvitelli redesigned the facade, and Ferdinando Fuga, under Ferdinand IV, created the Royal Apartments, sumptuously furnished and full of precious paintings, tapestries, porcelains, and other objets d'art.

To access these 30 rooms, climb the monumental Scalone d'Onore (Staircase). On the right is the Court Theater, built by Fuga for Charles III and his private opera company. Damaged during World War II, it was restored in the 1950s; note the resplendent royal box. Pass through three regal antechambers to Room VI, the Throne Room, the ponderous titular object dating to sometime after 1850.

In the Ambassadors’ Room, choice Gobelin tapestries grace the beige fabric walls and the ceiling honors Spanish military victories, painted by local artist Belisario Corenzio (1610–20). Room IX was bedroom to Charles's queen, Maria Cristina. The brilliantly gold private oratory has beautiful paintings by Francesco Liani (1760). The Great Captain's Room has ceiling frescoes by Battistello Caracciolo (1610–16); all velvet, fire, and smoke, they reveal the influence of Caravaggio’s visit to the city. A jolly wall-mounted series by Federico Zuccari depicts 12 proverbs.

Room XIII was Joachim Murat's writing room when he was king of Naples; brought with him from France, some of the furniture is courtesy of Adam Weisweiler, cabinetmaker to Marie Antoinette. The huge Room XXII, painted in green and gold with kitschy faux tapestries, is known as the Hercules Hall, because it once housed the Farnese Hercules, an epic sculpture of the mythological Greek hero. Pride of place now goes to the Sèvres porcelain.

The Palatine Chapel, also known as the Royal Chapel, redone by Gaetano Genovese in the 1830s, is gussied up with an excess of gold, although it has a stunning multicolor marble intarsia altar transported from a now-destroyed chapel in Capodimonte (Dionisio Lazzari, 1678). Also here is a Nativity scene with pieces sculpted by Giuseppe Sammartino and others. Another wing holds the Biblioteca Nazionale Vittorio Emanuele III. Starting out from Farnese bits and pieces, it was enriched with the papyri from Herculaneum found in 1752 and opened to the public in 1804. The sumptuous rooms can still be viewed, and there's a tasteful terrace that looks onto Castel Nuovo.

In the Bourbon stables, the Galleria del Tempo (open afternoons and evenings only) offers a multimedia trip through the history of Naples. The Museo Caruso (open mornings only) in the monumental Sala Dorica is dedicated to the great Neapolitan tenor Enrico Caruso.

Atop Posillipo's hill, this small yet magical complex has a 1st-century villa and two amphitheaters; access is though the Grotta di Seiano, a 2,500-foot tunnel cut though the tufa rock over two millennia ago. Guided tours (in Italian, book ahead) are given at 11 weekdays, 10:30 and 12:15 on weekends and holidays. Evening concerts are often held here in the summer.

Designed by Catalan architect Oscar Tusquets Blanca and opened in 2012, this is the most impressive of the numerous Stazioni dell'Arte on the city's Metro Linea 1. First archaeological remains and then mosaics by William Kentridge lead to a 165-foot escalator descending below Robert Wilson's glittering oval Crater de Luz. A 560-foot corridor, connecting the station to the Quartieri Spagnoli, is lined with light boxes depicting Razza Umana (Human Race) by Oliviero Toscani. Lauded by both CNN and Britain's Telegraph, it also won a prestigious ITA Tunneling Award in 2015.

This 12th-century castle, the oldest in Naples, was built atop the ruins of an ancient Roman villa on a thin promontory that dangles over the Porto Santa Lucia. Legend has it that the poet Virgil hid inside the villa an egg that had protective powers as long as it remained intact. The belief was taken so seriously that to quell the people's panic after Naples suffered an earthquake, an invasion, and a plague in quick succession, its monarch felt compelled to produce an intact egg, solemnly declaring it to be the original.

Today, the castle shares its views with some of the city's top hotels, and its gigantic rooms, rock tunnels, and belvederes over the bay are among the city's most striking sights. Some rooms are even given over to temporary art and photography shows. You enter below a forbidding trio of cannons. On the right is a large picture of the castle in Renaissance times. Turn left and look through the battlements to the intimate Borgo Marinaro below. An elevator on the right ascends to the castle top, or you can continue along the walkway overlooking the ramparts. The roof's Sala della Terrazze offers a postcard-come-true view of Capri.

Note that Castel dell'Ovo is closed for renovation work. Although it's scheduled to reopen in 2026, check on its status before visiting.

This small square 300 yards up the hill from Via Toledo is a shrine to Napoli's all-time favorite soccer player, Diego Maradona. "The hand of God, the head of Maradona," quoth the famous Argentina-born superstar after scoring, with the aid of his hand, a much-disputed World Cup goal against England in 1986. This sentiment and its ability to mix the earthly and fallible with the divine is also peculiarly Neapolitan.

The south wall is dominated by a mural of the Argentine giant featuring his original Swarovski diamond earring. Painted by fan Mario Filardi in 1990, when Napoli won their second league title, it was refreshed in 2016 with the face subsequently retouched by Argentine street artist Francisco Bosoletti (whose mural Iside, inspired by Pudicizia del Corradini in the Cappella Sansevero, is on the west wall). When Maradona passed away in 2020, fans gathered in the square to pay their respects, and people still honor the footballing hero by leaving photos, scarves, and other items here. There's also a giant mural of Maradona in the eastern suburb of San Giovanni a Teduccio, painted by Neapolitan-Dutch artist Jorit in 2017.

Fascinating 90-minute tours of a portion of Naples's fabled underground city provide an initiation into the complex history of the city center. Efforts to dramatize the experience—amphoras lowered on ropes to draw water from cisterns, candles given to navigate narrow passages, objects shifted to reveal secret passages—combine with enthusiastic English-speaking guides to make this particularly exciting for older children. Be prepared on the underground tour to go up and down many steps and crouch in very narrow corridors.

Founded in 1807 by Joseph Bonaparte and Prince Joachim Murat as an oasis from hectic Naples, this is one of the largest of all Italian botanical gardens, comprising some 30 acres. The 19th-century greenhouses and picturesque paths still provide a welcome refuge from the urban tumult, and there are important collections of shrub, cacti, and floral specimens from all over the world, as well as impressive groves of palm and citrus. A fascinating ethnobotanical museum shows how different cultures have utilized trees for everything from ropemaking to dye extraction. Next to the Orto Botanico, with a 1,200-foot facade dwarfing Piazza Carlo III, is one of the largest public buildings in Europe, the Albergo dei Poveri, built in the 18th and 19th centuries to house the city's destitute and homeless; it's now awaiting an ambitious restoration scheme.

An often overlooked sight in western Naples, this park—not to be confused with the Parco Virgiliano, at the western end of the Naples suburb of Posillipo—is named for the poet Virgil and is reputedly his burial site. The sign at the entrance indicates that not only (by legend) is Virgil's tomb here, but also the tomb-memorial of Giacomo Leopardi, the author of the evocative poem "L'infinito," who died during the 1837 cholera epidemic. As a safety precaution, victims of the disease were usually buried in mass graves, but the writer (and later politician) Antonio Ranieri, a close friend, arranged for this monument, which until 1939 was located elsewhere. From the Mergellina metro station, walk south to Salita della Grotta and turn right just before the church of Santa Maria di Piedigrotta; the park's entrance is just before the road tunnel.

Perched 500 feet above the Bay of Naples, this large urban park is worth the trip for its stunning vistas that face the islet Nisida with the formerly industrial area of Bagnoli stretching out below. A raised central area has a sports field where the Naples American Football team often trains.
