Lying at Italy’s geographic and historic heart, Lazio (or Latium) was the seat of the Roman Empire, and as such is teeming with ancient attractions, especially in the Eternal City of Rome itself. To the east, Tivoli has Emperor Hadrian’s exquisite and massive Villa Adriana. Civitavecchia, today a major cruise and ferry port, has been Rome’s main harbor since the second century. Many pre-Roman sites dot Lazio too, like the Etruscan necropolis at Cerveteri, dating from the 9th century BC.

Belgrade's long and storied history is suggested by its architecture, which varies from Byzantine and Ottoman to neoclassic and romantic buildings in the older neighborhoods, and from Art Nouveau to brutalism and neo-Byzantine design in New Belgrade. The city's many theaters, museums, monuments and opera houses boast a deep and fissured cultural life while the beaches and rivers attract sunbathers, sports enthusiasts and partygoers on the popular floating river barges that serve as nightclubs.
