The trulli of Alberobello have been designated as a UNESCO World Heritage Site. Built in the 15th century, the houses were intentionally constructed only out of stone, without mortar, so as to be easily demolished to avoid paying taxes. Great place to visit to ponder on how you, too, can stick it to the man.
Bari is the second largest city on Italy's southern mainland and the capital of the Puglia region. Here you can immerse yourself in nostalgia for historic Italy by strolling along the beautiful seaside promenade and by exploring Bari Vecchia, the Medieval old town. You can also visit the the remains of Saint Nicholas (famous for his stint as Santa Claus) in the Basilica di San Nicola; the 11th century Cathedral of San Sabino; and the Hohenstaufen Castle built for Frederick II, Holy Roman Emperor and King of Jerusalem.
The most fascinating castle built by Frederick II, Holy Roman Emperor and King of Jerusalem, the 13th century citadel served as his hunting lodge, and was later used as a prison and a refuge from the plague, before finally ending up on the Italian 1 cent Euro coin.
The spur on the Italian boot, Gargano is a promontory jetting out into the Adriatic sea. On it you will find the remains of the ancient Foresta Umbra, the only remaining portion of the forest in Italy; breath-taking views of the sea; and the oldest shrine in Western Europe dedicated to the archangel Michael, Monte Sant'Angelo sul Gargano. Some say it is also the only shrine consecrated by the archangel himself.
Puglia's White City, Ostuni is perched atop a hill overlooking the countryside of the Valle d'Itria, located just 5 miles from the Adriatic sea. Its white-washed buildings are a mixture of Gothic, Romanesque, and Byzantine architecture, while its Civic Museum and Archaeological Park houses the skeleton of a woman from Paleolithic times.
