GROTTA DI BOSSEA
Località Bossea, Frabosa Sottana (CN)
TEL 0174 349240
The Grotta di Bossea in upper Val Corsaglia is a true subterranean universe and a “living” cave in full evolution discovered 200 years ago. “Mateo 27 LUGLIO 1816” are the words found in the summer of 2015 in the Temple hall area and the oldest record confirming the discovery of the Bossea cave. In 1865, with the finding of the remains of Ursus spelaeus (cave bear), the first of its kind in Italy, Bossea’s fame spread quickly, albeit known simply as the Italian bone cave. Its internal river, named after local man Domenico Mora who strove more than all others to raise the cave’s visitor profile, has an annual average water content in excess of five million cubic metres, with flows oscillating between 50 and 2500 litres per second. This constant erosion process removes 750/800 tons of rock from the karst system every year. The visitor route develops for more than 2500 metres with an ascending level difference of 116 metres, equal to a 40-storey building. It has been estimated that the total volume of the visitor route, rounded down, is more than 900,000 cubic metres, with spaces large enough to hold up to three basilicas such as that of Vicoforte (the world’s largest dome with an elliptical section). This places Bossea among the largest cave systems in Italy in terms of volume and second only to the Grotta di Frasassi (AN). Another major peculiarity which can be observed by visitors is the fact that at least 50% of the area open to the public is hewn into volcanic rock which is impermeable to water, an apparent contradiction that only adds to the geological, informative and educational interest of the Bossea subterranean system.
