Langdon deduces that the first step – earth – leads north, to the Piazza del Popolo. Awesome movie location!
Next movie location - Santa Maria Della Vittoria church. This is where the first cardinal was murdered with his chest branded with the word "Earth"
We skipped the second movie location, cause it takes place in Vatican & you will have to walk twice around the city. The third cardinal was burnt in in Santa Maria della Vittoria church with the word "Fire" branded on him.
Besides being a famous movie location, Pantheon is also one of the most visited touristic spots in Rome. Robert and Vittoria visited Raphael Santi's grave here and you can do that too!
Fontana dei Quattro Fiumi or Fountain of the Four Rivers, designed by Gian Lorenzo Bernini in 1651, is the 4th element on the Path of Illuminati - water. This is where Robert finds the 4th cardinal, who is supposed to die here. However, Langdon saves him.
Robert and Vittoria enter the The Mausoleum of Hadrian or in Italian Castel Sant'Angelo. Here they find a hidden route that leads them to Vatican (please, don't try to find this route, it's forbidden) :)
Well, no need to say, even if you are not a big movie fan, St. Peter's Square or Piazza San Pietro is a must-go place, if you visit Rome! Piazza San Pietro is also such famous movie location - Roman Holiday, When in Rome, Spectre 7 many other movies were filmed here!
The Pope is being elected at Sistine Chapel. In case you're visiting Rome by the time when Sistine Chapel is open to it's visitors, then definitely get inside, it's truly awesome place (note: buy tickets beforehand to avoid queues)
Robert Langdon FINALLY received permission to get inside the Vatican Secret Archive. In real life, getting that permission is really hard, so don't even try (in case you are Robert Langdon)
