Monte di Procida falls within the perimeter of the Campi Flegrei Regional Park - a protected natural area of volcanic nature that testifies to the complex geological history of the Campi Flegrei, one of the most studied in the world - and stands out for having the largest cliff in Torrefumo of "Breccia Museo". An extensive pyroclastic flow attributed to the Campana ignimbrite whose particular and evident stratification describes well even to non-expert eyes, the geological evolution of the territory: in a continuous stratigraphic succession the dynamics that in about 40,000 years led to the formation of the landscape are visible as it appears today. Along the Coasts of Monte di Procida in the Miliscola - Torregaveta stretch, the oldest deposits of Phlegraean volcanism emerge which, from bottom to top, tell the main eruptive events that characterized the entire Phlegraean area. The conformation is so unique that it inspired geologist Henry James Johnston-Lavis in 1889 who, observing it from nearby Procida, baptized it precisely Breccia Museo. Every year La Breccia Museo is the subject of study visits by both amateurs and enthusiasts and geology students from Italian and foreign universities.
