Sciarra's funeral scene is taking place at Museo della Civiltà Romana (in english: Museum of Roman Civilization). In this scene we see Sciarra;s wife, played by Monica Belucci. Museum of Roman Civilization is one of the most famous museums in Rome, so yeah, definitely a must-go place.
Another scene, another beautiful view. Bond steals the luxury Aston Martin to find Sciarra's widow. In one of the shots he's passing by Colosseum. No need to say that it's a must visit place in Rome!
This is where the spectacular Aston Martin drowns in the Tiber. It happens near the Ponto Sisto bridge.
In another scene, on his way to the Sciarra's funeral James Bond passes through the famous Porta San Pancrazio, which houses the National Association of Garibaldi Veterans and Survivors along with the Garibaldi Museum!
In the chase scene, where Bond is being followed by one of Spectre's assassins in Rome, they pass by Via della Concilliazione, which takes them to Piazza San Pietro.
Well, if you see someone is racing on Aston Martin near Piazza San Pietro, make sure to hide in a safe place. The history shows that all these Bond chases do not end good for people around!
Passetto di Borgo or just Passetto was built in 1277 and racing through it on Aston Martin is actually a very bad idea. Have a nice walk there!
Attention, if you decided to take this tour on car, do not, we repeat, DO NOT ride down the Lungotevere Arnaldo da Brescia stairs. Instead go to the nearby Villa Borghese gardens, it's one of the most beautiful parks in Rome.
