Naples Cathedral

Duomo di Napoli, Cattedrale di Santa Maria Assunta or Cattedrale di San Gennaro

Built in the 18th century, it is the main church of Naples. It is widely known as the Cattedrale di San Gennaro, in honour of Saint Januarius, the city's patron saint. It was built on the foundations of two palaeo-Christian basilicas, whose traces can still be clearly seen. Underneath the building, excavations have revealed Greek and Roman artifacts. The Cathedral is famous for Miracle of the Blood, a recurring miracle taking place on the first Saturday of May and September 19th every year. During the ritual an ampule containing the old dried out blood of Saint Januarius is brought out and stirred; and miraculously liquefies. According to legend, disaster will befall Naples if the blood fails to liquefy. Service times can be found on the cathedral website; for the miracle, you must get there about 90 minutes early to be assured a seat. The Royal Chapel of the Treasure of St. Januarius next to the cathedral holds the extensive treasure and can be visited for 14€ from 9:30-18:00 o'clock.

Di Matteo

Il presidente, Sorbillo, and his sister, a few doors away (informally known as "la vecchia", the old lady, from the owner of the pizzeria, a very small place with only 4 or 5 tables, that looks like a pizzeria of 50 years ago - very hard to find, but it's worth it!) You can get pizzas to eat on the go.
