Rome is the capital city of Italy located along the Tiber River near the Tyrrhenian Sea. It is worth visiting for its fascinating and ancient sites like the Colosseum where gladiators fought, as well as its variety of theaters, obelisks, and forums offering spectacular views. As the origin of the Roman Empire and the Renaissance, Rome had a profound impact on world history but its underground transportation system is limited. Key sites to experience the "eternal soul" of Rome include the Trevi Fountain, Vatican Museums, and dome for breathtaking views.
