Rome's Must-See Sights

Standing inside the Colosseum at opening hour when the stones still hold two thousand years of chill, tossing a coin over your shoulder into the Trevi Fountain at noon, drifting through Trastevere's alleys at dusk as the smell of fresh pasta spills from open kitchens, watching the Tiber turn gold under the streetlamps from Ponte Sant'Angelo at night—Rome isn't a city you can simply check off. Every paving stone hides a layer of history, and every corner might surprise you with a Michelangelo. Walk all 15 of these places and you'll understand why all roads still lead here, and why you won't quite want to leave.
