Rome

Rome draws over 33 million tourists annually, more than double the visitors of #3 Florence. The Colosseum, dating from 72 AD, the Vatican City, and the Trevi Fountain form an unmatched trio spanning three millennia. As Italy's capital since 27 BC, it offers a cultural depth that outperforms #2 Venice by offering ancient ruins woven into a vibrant modern metropolis. Every street uncovers 3,000 years of layered history, making it the definitive starting point for any Italian journey.
