Discover Rome's historic sites with a walking tour inspired by Dan Brown's Angels and Demons. Start at the Church of Santa Maria della Vittoria, also known as the stage for Langdon's discovery of the third fallen cardinal, branded with a fiery mark.

Then, visit the Pantheon and Santa Maria del Popolo and look at the beautiful architecture of these attractions. Next, explore St. Peter's Basilica, Repubblica Square, and Navona Square, where Langdon finds the final cardinal, marked with the essence of water.

End your tour at Castel Sant'Angelo to learn about the Passetto passage that leads all the way to Vatican City.
