Alberobello, in Puglia, with its Trulli is one of the 51 Italian sites included in the UNESCO World Heritage List. The name derives from the late greek τρούλος, or "cupola" and indicates the ancient conical constructions in dry stone, of prehistoric origin. The historic center of Alberobello is entirely made up of these particular pyramid-shaped buildings that make it unique in the world. According to some studies, the trulli of Alberobello date back to the mid-fourteenth century. Trulli are a unique example of ancient construction that survives and is still used today. Visit the stupendous Alberobello is like traveling to a country with no time. At about 1 hour away by car, there is Ostuni. The "White City" is climbing on three hills. Suspended between the southern Murgia and the high Salento, Ostuni, candidate for the title of "Italian Capital of Culture 2018," gives the best of Puglia. Within the country between immaculate homes often dug into the rock, arches and noble palaces, Baroque views and golden stone churches, is the beautiful Cathedral. Just outside, the sea! Across the road down between farms and olive trees, you reach the beach of Crete Rossa, one of many that dot the 17 km of the City of Ostuni coast. This is a place to "local" more than tourists, with small coves and beaches of fine sand and rocks, ideal for seeking peace.
