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.
