The houses painted in white lime and the peculiar topography have earned Ostuni fairy epithets, as "White City", "Queen of Olives", "Nativity city".

The old city, in fact, called "La Terra", is unique and unmistakable: the blinding strictly white monochrome color of its town is its characteristic. The streets and delightful stores, but especially the blue sea, make Ostuni one of the most charming villages of our Puglia: its crystal clear waters, the beauty of its coast and the beach services offered, have made worthy to receive the Blue Flag and five sails of Legambiente, becoming, in 2014, the city with the cleanest sea in Italy.
