Located at the gateway to Valle d’Itria, just a few kilometres away from enchanting small towns such as Alberobello, Borgo Egnazia, Polignano a Mare and Castellana Grotte, the Catellana Caves are one of the most beautiful and spectacular underground cavity complexes in Italy, of karstic origin formed in the Cretaceous period (about ninety to one hundred million years ago).
They extend over a length of 3348 metres and reach a maximum depth of 122 metres.
