Most scholars see Numana as having been founded by people of Sabine origin, but Pliny the Elder attributed its foundation to the Siculi, but whatever its origin, it was an important commercial centre in the 6th and 5th centuries BC. In about 500 BC, the expansion of Roman power and the later foundation and growth of Ancona led to the decline of Numana. However, it maintained a certain importance, becoming in the 5th or 6th century an episcopal see. In the Middle Ages the town is referred to under the name Humana Umana in modern Italian spelling and under that name appears in a number of treaties, alliances and other documents. In 1404 it came under the control of Ancona and in 1432 the diocese was united to that of Ancona. In 1553 the bishops of Ancona became also civil rulers of Humana and assumed the title of Conti di Umana. In the 19th and 20th centuries the town resumed its ancient name of Numana.
Geography
Numana is a central Adriatic coastal town, which lies at the southern foot of Monte Conero. 91.8% of the area falls within the Conero Regional Park. The old town is often called "Numana alta" as it is on top of a cliff overlooking the sea and can be described almost in continuity with the settlement of Sirolo, while "Numana bassa" includes the area around the port. The beach of "Numana alta" comprises two bays formed close to the cliff: the Spiaggiola Beach and the friars and the beach of "Numana bassa" extending to the south of the port village of Marcelli. The inner part of the territory is mainly hilly and at the mouth of the Musone River, a wet area of significant natural and environmental value.
Main sights
The Sanctuary of the Crucifix was built in 1968 to replace an earlier building, attributed to Pellegrino Tibaldi. Some of the frescoes of the vault, by the painter Andrea Lilli were retained and a crucifix in wood, which most likely was transported by ex-emperor Charlemagne as a gift for Pope Leo III, but due to a storm Emperor was forced to stay in the town and there abandoned it, after which it was found at sea after an earthquake. In contrast to the baroque Church of Saint John the Baptist, the modern church has a base with an octagonal spire and the main entrance is located before the Bishops Palace, seat of the town of Numana.
The Bishop's Palace belonged to noble families in Rome and was then purchased by the bishops of Ancona as a summer residence. Today it is the city hall and hosts exhibitions.
The Arco di torre and aqueduct reveal evidence of Roman rule. Within walking distance of each other, the arc is the remnant of a tower and was used as an outpost to prevent attacks by invaders in the Adriatic Sea, while the aqueduct, embellished with a fountain, supplied water to the town until a few decades ago.
Frazioni

Located from the town of Numana, Marcelli was built on a swamp that was reclaimed by the lords of Numana and extends to the Musone River, the southern boundary of the municipality. There are the main seaside resorts of the Riviera del Conero, campsites and holiday clubs. Svarchi, located west of the border with the comune of Sirolo. The town lies on a hill.
