Regional Park of the Phlegraean Fields is a protected territorial entity encompassing the volcanic and coastal landscape west of Naples in Campania. The park includes volcanic calderas, coastal cliffs, thermal springs, ancient ruins and a mosaic of urban and rural zones that link Pozzuoli, Bacoli, Monte di Procida, Ischia, and Procida. It is situated within the larger Campanian volcanic arc and overlaps areas of archaeological, geological and ecological significance recognized by Italian and European authorities.

Geography and geology

The park occupies part of the Phlegraean Fields (Campi Flegrei) caldera complex north of the Gulf of Pozzuoli and west of Mount Vesuvius, integrating coastal promontories such as Punta Epitaffio and inland depressions like Solfatara and Agnano. Major geomorphological features include the Lake Avernus volcanic maar, the Monte Nuovo lava dome created during the 1538 eruption, resurgent domes and fumarolic fields around Pozzuoli. The area is traversed by fault lines associated with the Apennine Mountains thrusting and the subduction of the African Plate beneath the Eurasian Plate, with magmatic reservoirs linked to the Campanian Ignimbrite eruption and the Phlegraean Fields bradyseism phenomena. Hydrothermal manifestations—thermal baths at Baia, steaming vents at Solfatara, and mineral-rich springs—result from magmatic-hydrothermal interaction, while marine terraces along the Bay of Naples record Quaternary sea-level changes and Holocene coastal evolution.

History and cultural heritage

Human occupation in the park spans prehistory to the modern era, with evidence from Neolithic Italy through Classical Roman Republic and Roman Empire periods. The park contains Roman villas at Baia and Cumae with submerged archaeological sites in the Gulf of Pozzuoli, imperial-era infrastructure such as the Via Domitiana, and religious sites linked to Greek colonists from Cumae (ancient city). Medieval and Renaissance layers include fortifications at Castel dell'Ovo provenance connections, maritime activity centered on Pozzuoli Port and early modern spa architecture at Terme di Agnano. Notable historical episodes tied to the area include accounts by Strabo, seismic and volcanic crises referenced by Pliny the Elder and Pliny the Younger, strategic use during the Napoleonic Wars, and scientific study by figures like Amedeo Avogadro in the context of regional geology. Archaeological discoveries continue via institutions such as the Superintendence for Archaeological Heritage of Naples and the University of Naples Federico II.

Biodiversity and ecosystems

The park supports Mediterranean maquis, coastal dune systems, salt marshes near Lago Miseno, and thermophilous vegetation on solfataric soils, hosting flora documented by the Italian Botanical Society and fauna recorded by the Italian Zoological Union. Habitats sustain birdlife including species monitored by LIPU and BirdLife International programmes, with migratory pathways across the Tyrrhenian Sea corridor. Marine habitats along the park’s coastline support Posidonia meadows studied by the Stazione Zoologica Anton Dohrn and invertebrate assemblages described in surveys by the Italian Institute for Environmental Protection and Research. Endemic and specialized taxa colonize fumarolic substrates, while agricultural mosaics around Bacoli and Monterusciello host traditional orchards and vineyard varieties linked to Campania wine denominations recorded by the Ministry of Agricultural, Food and Forestry Policies.

Protected areas and management

The park interfaces with multiple protection regimes including regional ordinances from the Region of Campania, conservation categories under the IUCN framework promoted by Italian authorities, and Natura 2000 sites designated under the European Union Habitats Directive and Birds Directive; relevant SACs and SPAs overlap parts of Baia and the Gulf of Pozzuoli. Management involves collaboration between municipal administrations of Pozzuoli, Bacoli, Monte di Procida, the Metropolitan City of Naples, the Campania Region environmental directorate, and research partners such as the Italian National Institute for Geophysics and Volcanology (INGV) and the National Research Council (Italy). Cultural heritage is curated in museums including the National Archaeological Museum of Naples and local municipal collections, while marine protected area frameworks coordinate with the Directorate-General for Maritime Affairs.

Recreation and tourism

Tourist attractions combine archaeological tourism at Baia Archaeological Park and Cumae Archaeological Park, thermal tourism at Terme di Agnano and Baia, coastal recreation along Miseno Beach and boat excursions to Procida and Ischia, and geotourism such as guided visits to Solfatara and educational trails managed with university outreach from Università degli Studi di Napoli "L'Orientale". Cultural events tie to festivals in Pozzuoli and gastronomy routes featuring Campanian cuisine and seafood from the Tyrrhenian Sea. Transport links include regional rail and ferry services connecting Naples Centrale and Molo Beverello with the park’s nodes, and visitor information is provided through tourism boards like the Campania Tourism Board.

Conservation challenges and research

Conservation issues combine volcanic hazard management—monitoring by INGV for bradyseismic uplift and gas emissions—with protection of submerged archaeological sites threatened by coastal erosion and sea-level rise studied in programs with the Intergovernmental Panel on Climate Change (IPCC) scenarios. Urban expansion pressures from Naples metropolitan growth, invasive species research by the Italian Botanical Society, and pollution impacts on Posidonia meadows assessed by the European Environment Agency complicate management. Ongoing research projects involve interdisciplinary teams from University of Naples Federico II, Stazione Zoologica Anton Dohrn, INGV, and international partners in EU-funded initiatives addressing geohazard early warning, heritage conservation technology, and marine ecology restoration. Stakeholder engagement includes municipal councils, heritage NGOs, academic consortia and EU cohesion policy instruments aimed at balancing tourism development with long-term preservation.
