About Rome

Rome layers nearly three thousand years of history into one walkable city, from the Colosseum and Forum to Baroque piazzas and Vatican art.

Ancient Rome is still in plain sight. The Colosseum, the Roman Forum and the Palatine Hill sit together at the city's heart, the Pantheon still stands with its open oculus, and fragments of temples and aqueducts turn up between apartment blocks. Across the Tiber, Vatican City holds St Peter's Basilica, the Vatican Museums and Michelangelo's Sistine Chapel ceiling.

Top-ranked sights in Rome: Colosseum, Vatican Museums, Sistine Chapel.
