Where the scalding earth burns
The name ”Phlaegrean Fields” refers to the vast area of a volcanic nature lying northwest of Naples (the word “Phlagrean” comes from Greek and means “fiery”). The area boasts some twenty volcanic craters: several of them like the remarkable Solfatara emit jets of steam with sulphurous fumaroles while others, like Agnano, Pozzuoli and Lucrino, are renowned for their hydrothermal activity. For centuries, the entire area and, in particular, Pozzuoli, have been subjected to a phenomenon of Bradyseism which causes the ground to rise or sink a few metres above or below sea level. Since time immemorial, the unit of measurement for this phenomenon has been the Temple of Serapis in Pozzuoli whose pillars are marked by traces of salt which enable experts to gauge to what extent the ground has shifted above or below sea level. A number of lakes can also be found in the Phlaegrean area: Lake Averno, Lake Fusaro, Lake Lucrino and Lake Miseno, known in ancient times as the “Dead Sea”. The main areas of cultural and environmental interest are: Cape Miseno, the largest military port in ancient Rome, the Greek city of Cuma, the Underwater Archaeological Park of Baia whose villas and temples are situated below sea level and the Rione Terra in Pozzuoli featuring a Roman city buried under its new constructions. These and countless other natural treasures make the Phlaegrean Fields a must-visit tourist attraction.
