The Abyss Anconais the first part of the cave and the researchers gave to it the name of their city. it is a big hollow, perhaps one of the bigger hollow in Europe and in the world: 180 m. long, 120 m. large and 200 m. high. At the end of the abyss it is possible to see a caotic hoard of blocks, results of movements and fallings down from time immemorial that gave origin to the abyss.
