The caves of Castellana, extended for about 3 kilometers, open up to 330 m above sea level less than 500 meters from the town of Castellana. The entire municipal territory is characterized by calcareous rocks composed essentially of calcium carbonate, mainly of the limestone type of Altamura. The natural entrance to the caves is a huge sixty-meter deep chasm called the Grave. The visit to the public winds along a scenario for about 1 km. The longer route takes two hours and runs for 3 km, among caves and chasms to which mythological or fantastic names have been given. From the Grave to the Black Grotto or the Capitoline Wolf, after passing the Cavernone dei Monumenti, past the Calza and then the Caverna della Civetta, crossed the Corridor of the Snake, the Cavern of the Precipice and the Little Paradise, one runs along the long Corridor of the Deserto also known as the Grand Canyon underground of a reddish color due to the presence in this stretch of iron minerals we reach the Cave of the Tower of Pisa, the clear dripping water Pond, the Red Corridor, the Cave of the Cupola and finally passing from the shimmering Laghetto di Cristalli, one reaches the White Grotto, a luminous and shining cavity.
