The Archaeological Museum of the Phleagrean Fields, hosted inside an Aragonese castle, preserves the main artifacts coming from the site of Cuma, Pozzuoli, Baia and the other cities of the surroundings. Here you can see vases, grave goods and sculptures intended to decorate villas and public buildings, as well as the section dedicated to the temples of Cuma and to the Roman colony of Pozzuoli. From here you reach the Archaeological Park of the Thermal Baths of Baia, to see the ruins of public and private thermal baths that made this town the favorite spa resort for the Roman patricians.
