Frattamaggiore (locally also known as Fratta) is a comune in the Metropolitan City of Naples, Campania, Italy. It is located 15 km (9.3 mi) north of Naples and 15 km (9.3 mi) southwest of Caserta. It was awarded the title of "City of art" in 2008 and named Benedictine city in 1997.
The first records of Frattamaggiore date to 921 AD, although the area was probably settled in pre-Roman times. The people of Atella built a watchtower in response to the Vandal invasion of 455 AD, around which refugees from Miseno settled when their town was razed by the Saracens; here they also built a Catholic church in honour of Sossius, now the patron saint of Frattamaggiore.
