Most tourists who come to Puglia arrive fascinated by its beautiful sea and beautiful beaches. Nobody imagines that this land, rich in vineyards and centuries-old olive groves, but also of cities of art and ancient ones, hides under a few meters of depth most surprising miracles that nature could create.

It is the Castellana Caves, a complex of underground cavities of karst origin that extend for about 3 kilometers, until reaching a depth of 70 meters.

As often happens, the discovery was unexpected: the abyss leading to the caves was used by the locals as a landfill. As a tribute to the discovery, the town called Castellana a few years later was renamed Castellana Grotte.

And the fact is not surprising, because the caves are the largest, but also the most beautiful complex in Italy. It's a fantastic scenery, full of glare of lights, with beautiful stalactites, narrow alabaster blades and powerful stalagmites with bizarre shapes.

If you can, see the caves at night (they are open late at the fair held at the end of July) when the stalactites, stalagmites appear even more magical Castellana Grotte is not only the caves.

The town also has a nice and nice old town, with characteristic stone houses overlooking the narrow and winding streets, and palaces Gentiles of the 17th and 18th centuries rich in arches, mullioned windows, frescoed balconies and old noble coats of arms.

It is also dotted with numerous churches including the Mother Church, rich in Renaissance and Baroque paintings.
