Frasassi Caves
Marche
The Frasassi Caves, located in the municipality of Genga in the Marche region of Italy, form one of the most famous karst cave systems in the country. Discovered initially in 1948 and significantly expanded upon in the 1970s, these caves feature an extensive network of underground chambers and passageways rich in impressive stalactites and stalagmites formations. Notable chambers include the vast Abisso Ancona, a cavern large enough to contain Milan's Duomo, the Grotta delle Nottole housing large bat colonies, and the Sala delle Candeline named for its candle-like stalagmites. The caves also hold scientific significance, having hosted chronobiological experiments and microbiological research on extremophile biofilms. Nearby, two chapels stand as historical landmarks: the 11th-century Sanctuary of Santa Maria infra Saxa and the 19th-century Tempietto del Valadier. The site is protected and managed to balance scientific study and tourism, attracting millions of visitors since opening to the public in 1974. Their vast size, natural beauty, and scientific importance make the Frasassi Caves a unique destination for nature lovers and researchers alike.

History
The Frasassi Caves were first entered in 1948 by a local farmer, with further entrances discovered by Italian Mountaineering Club members in the 1950s and 1960s.
The major discovery of the Grotta Grande del Vento occurred in 1971 by a group of speleologists led by Giancarlo Cappanera, revealing vast underground chambers including the enormous Abisso Ancona.
Since 1974, the caves have been open to the public and protected by the Consorzio Frasassi to preserve their natural and scientific value.
Over the decades, the cave system has expanded to over 30 kilometers of explored passageways, becoming a major tourist and research site in Italy.
