The Campi Phlegraei (Phlegraean Fields) is a large caldera (13 km wide) in the Bay of Naples region of Italy. In total, the the area comprises 24 craters, although a good portion of the caldera now lies under water. The area was important in Greek and Roman times; the Greeks established their first mainland colony at Cumae within the Campi Phlegraei.

Details:

Surviving Hellenistic Greek sources treat the Phlegrean Fields as a large area, roughly bounded by Capua, Nola, and Mount Vesuvius. Writers of the Roman period seem to have in mind a smaller area, lying between Cumae and Puteoli (Gargini provides citations in Brill's New Pauly). Modern vulcanologists refer to the Campi Flegrei volcano, understanding its location, extent, and history from a scientific perspective that both differs from and contextualizes the ancient perspectives (see Costa 2021, pages 4-8 and map in Figure 3).
