Our visitor maps out 24 hours in Italy's third-largest city, says Conor Power.
The 10-minute walk between the Duomo (Naples Cathedral) and Cappella Sansevero takes you through narrow streets full of sing-song exclamations, buzzing mopeds and manic activity. In the cathedral, the blood of San Gennaro (St Januarius) is kept in a phial and miraculously liquefies thrice yearly. If not, disaster befalls the city. Also at the Sansevero Chapel is the hauntingly lifelike sculpture of the Veiled Christ.

The Museo Archeologico Nazionale di Napoli is simply unmissable. Despite a layout of gloriously jam-packed chaos, it has fabulously rewarding displays from Ancient Rome, such as the Farnese Bull on the ground floor. On the upper floor, you can see all the best artefacts from the cities of Pompeii and Herculaneum just down the road, including the over-18s-only erotica of the twin cities' brothels and houses in the Gabinetto Segreto (secret room).

The passeggiata, or evening stroll, is a great Italian tradition, and the half-hour walk from the port area in front of the Castel dell'Ovo, past Piazza del Plebiscito and along the waterfront by Via Francesco Caracciolo to the tennis club gives an impression of the more grandiose side of Naples - not to mention some splendid views of the gorgeous, blue Bay of Naples and the brooding presence of Mount Vesuvius in the background.

Naples is the home of pizza - the real one. Here it's very simple but tasty and cheap. Even somewhere like Da Michele (located at Via Cesare Sersale 1; damichele.net) provides great Neapolitan pizza at very affordable prices, despite serving the ranks of the rich and famous, including Julia Roberts stuffing her face in Eat Pray Love. At 8pm, it's lively but not overly busy. Buon appetito!
How: Get off at the Umberto I-Poerio bus stop on Corso Umberto I.
