Southern Italy is home to a beautiful blue paradise. No, it's not Pantelleria with its endless blue ocean or this other underrated, clear-watered Italian island. It is actually the little-known town of Casamassima in Puglia. Here, the color blue floods the town's center.

The buildings, the flower pots, and even the bicycles are painted in a rainbow of blue-ish hues, giving Casamassima the name of "Il Paese Azzurro," meaning the Blue Country — a destination so picturesque that anyone traveling through Italy's Meridione region must visit at least once.
