Cumae was established on the Campanian coast by Greek settlers from Euboea during the eighth century BCE, following an earlier foothold on the island of Pithekoussai. Often regarded as the first lasting Greek colony on the Italian mainland, it occupied an acropolis overlooking fertile plains and a protected coastline. The settlers encountered and exchanged with Indigenous communities, bringing Greek language, ritual, pottery, and alphabetic writing. Through such contacts, the Euboean form of the Greek alphabet helped shape the scripts later adopted by Etruscans and Romans.

The colony grew through agriculture, maritime exchange, and influence over neighboring settlements. Cumaean founders helped establish other cities, including Neapolis. Temples crowned the acropolis, while the lower city contained houses, streets, workshops, public spaces, and cemeteries. The sanctuary of Apollo and a temple later associated with Jupiter dominated the heights. Literary tradition made Cumae the home of the Sibyl, the inspired prophetess who guided Aeneas to the underworld in Virgil’s Aeneid, giving the landscape an enduring place in Roman cultural memory.

Cumae fought Etruscan expansion and won important battles in the sixth and fifth centuries BCE, at times with allies from Syracuse. Oscan-speaking Samnites captured the city in 421 BCE, and Rome incorporated it during the following century. Roman Cumae retained Greek prestige while acquiring new walls, roads, baths, an amphitheater, monumental gates, and a great sanctuary landscape. The nearby Via Domitiana and regional ports integrated it with Puteoli, Baiae, Misenum, and the dense commercial and military world of the Bay of Naples.

Christian communities reused the acropolis temples as churches, and Cumae became a bishopric in late antiquity. Warfare and insecurity transformed the ancient heights into a fortified settlement. In 1207 Neapolitan forces destroyed the stronghold, fearing its use by raiders, and population shifted away. The so-called Cave of the Sibyl, a long trapezoidal passage discovered in the 1930s, became the site’s most famous feature, although scholars debate its original function and caution against treating a powerful literary association as a settled archaeological identification.

The Archaeological Park of Cuma now brings together the acropolis, sanctuaries, Sibyl’s passage, defensive works, and parts of the lower city. Research continues across a site whose size and long occupation leave much unexcavated. Conservation must address volcanic geology, vegetation, drainage, and fragile rock-cut spaces. Cumae’s history reaches far beyond its oracle legend: it was a laboratory of contact among Greeks, Indigenous Italians, Etruscans, Samnites, Romans, and Christians, and a starting point for cultural changes that shaped writing and urban life across ancient Italy.
