Naples Cathedral (Cattedrale di Santa Maria Assunta, commonly called the Duomo di Napoli) is the archiepiscopal church of Naples, with major construction begun in the late 13th century and consecration completed in the early 14th century. It is the city’s principal cathedral and the seat of the Archbishop of Naples.

The interior combines Gothic structure with later Renaissance and Baroque decoration; highlights include the richly ornamented chapels, large frescoes and marble altars. The cathedral is best known for its association with Saint Januarius - it contains the saint’s relics and a large chapel with the church treasury. Visitors also often see the baptistery and archaeological remains under the building.

Construction began in the late 1200s under Angevin rule and the building was altered repeatedly in subsequent centuries, adding Baroque chapels and 19th century restorations to the medieval core. The Cappella del Tesoro became an important repository for donations and ex-votos, reflecting the cathedral’s long role as a civic and religious centre.

The cathedral sits in Naples’ historic centre on Via Duomo, in the district often called the Cathedral Quarter, within walking distance of other major historic streets such as Spaccanapoli and the main archaeological sites of the city.

• San Gennaro relics: The cathedral houses the relics of Saint Januarius and is the focal point for the traditional blood relic ritual associated with the saint.
• Treasure and museum: A treasury museum adjacent to the chapel displays jewellery, votive offerings and liturgical silver accumulated over centuries.

What to See#

• Cappella del Tesoro di San Gennaro: A richly decorated chapel that preserves the relics and treasure associated with Saint Januarius, including reliquaries, ex-votos and precious metalwork; the chapel is a major draw within the cathedral.
• Baptistery / Crypt: An early Christian baptistery and lower-level spaces beneath the cathedral that contain archaeological remains and early liturgical fittings dating back to Late Antiquity.
• Nave and Main Interior: The cathedral nave and transept area showing the mix of Gothic, Renaissance and Baroque workmanship produced by successive restorations and additions across centuries.

The Duomo di Napoli (Naples Cathedral) sits on Via Duomo in central Naples. From Napoli Centrale (Stazione Centrale) it is an easy walk of about 1.2 km (roughly 15-20 minutes) down city streets to Via Duomo; alternatively from Piazza Garibaldi you can catch Metro Line 1 (direction Piscinola) one stop toward Museo and walk about 8-12 minutes to the cathedral along city streets. If driving from Naples International Airport (Capodichino) expect roughly 7-9 km to the historic centre (depending on route) via the A56/E45 and follow signs to the city centre/Corso Umberto-Via Duomo; central parking is limited, so arriving by train or metro is usually simplest.

• Aim for the cathedral right at opening on weekdays to avoid the tour groups that swarm mid-morning; mornings also give the best chance to move freely into side chapels and view details without services in progress.
• Buy a separate ticket or check opening hours for the Museo del Tesoro (Treasure of San Gennaro) - it's in the complex but runs on different hours and is often missed by visitors focused only on the main nave.
• If you're interested in the famous liquefaction miracle, check the well-known feast dates (including Sept 19 and Dec 16 and usually the first Saturday in May) and plan around them - those days draw large crowds and different security/entrance arrangements.
