1. The Colosseum and the Arch of Constantine
As the Eiffel Tower is to Paris, the silhouette of the Flavian Amphitheatre is to Rome. The largest structure left to us by Roman antiquity, the Colosseum still provides the model for sports arenas – present day football stadium design is clearly based on this oval Roman plan.
2. Vatican City
The Vatican is the smallest independent state in the world, with an area of less than half a square kilometer, most of it enclosed by the Vatican walls. Inside are the Vatican palace and gardens, St. Peter’s Basilica, and St. Peter’s Square, an area ruled by the Pope, supreme head of the Roman Catholic Church. This compact space offers a lot of things to see, between its museums and the great basilica itself.
