5The Pantheon

The Pantheon is one of the best-preserved ancient Roman buildings and has been standing for nearly 2,000 years.

Its grand dome and stunning interior are admired by millions of visitors annually. It’s a free attraction, which adds to its popularity. As one of Rome’s most beloved landmarks, the Pantheon is usually crowded, especially in the middle of the day.
If you want to experience this awe-inspiring building with fewer people around, visiting early in the morning is a good idea.
