Ultramodern towers define Riyadh's skyline, hinting at the Saudi capital's sophisticated culture, shopping, and dining. Prayer times set the pace for life in one of the country's most conservative cities, and gleaming architecture blends with historic landmarks from the kingdom's earliest years.

A Puglia port town that’s equal parts historic and functional, Monopoli makes a splash with medieval churches and castles jutting above the Adriatic. It’s also a painter’s dream, with bright blue fishing boats adding a pop of colour against whitewashed harbour walls.

It’s nicknamed the Eternal City for a reason. In Rome, you can drink from a street fountain fed by an ancient aqueduct. Or see the same profile on a statue in the Capitoline Museum and the guy making your cappuccino. (Which, of course, you know never to order after 11 am.) Rome is also a city of contrasts—what other place on earth could be home to both the Vatican and La Dolce Vita?
