For world travelers, the consensus is usually that you shouldn't visit a place more than once -- there are so many other cities and countries to see! Personally, that rule gets broken for one place for me: Italy. I'll go back as many times as I possibly can in my lifetime and encourage those who can to do the same. It's culturally rich and there's always something new to see. Get started on your trip planning now: Can you match the Italian city to the famous site?
