Turin is nicknamed "The Magic City" because of the presence of myths and legends of esoteric cults. The city is known as one of the points of both the triangles of black magic (with London and San Francisco) and white magic (with Prague and Lyon) in the world. The landmark of Turin, the Mole Antonelliana, is one of the esoteric symbols of white magic of the city. According to experts of esotericism, this would be a huge antenna that stretches to the sky and radiates positive energy taken from the underground of the city. Among other things the statue of the Faith in front of the Gran Madre church has an eye towards the building, which might host the Holy Grail.
