An angel who fell from the sky
The area of Piazza Statuto in Turin was probably used during Ancient Roman times as a necropolis. And, still more macabre, as an area for executions: this is probably the reason why the legend was born (it is very well known that Turin is the City of Misteries and esoteric legends) and that on the peak of the Monument to the Frejus Tunnel at the centre of the square, there's Lucifer. This monument was built in 1879 by the at the time sculptor Luigi Belli, upon request of Count Marcello Panissera di veglio, the President of the "Accademia Albertina di Belle Arti" of Turin. This sort of mountain or pyramid is built with rocks actually coming from the tunnel: the structure shows Titans as tired bodies; The peak shows, with his huge, opened wings, the scientific genius so as to symbolize a victory of intellect on strength. Someone started to say that those wings are the ones of that Fallen Angel that God let fall from heaven: Satan in person. The wings would in fact point to trace the so called "black triangle" with two other esoteric cities: London and San Francisco.
This statue is a fountain and is an access to a primary point of the sewage system: the surface and underground join in fact through the Monument of the Frejus Tunnel, another element that fuelled the abovementioned legend. Are all these things untrue? Of course they are. Still, it is still fun to tell these kind of stories! If you would like more stories just like this one, there are dozens of guides on Esoteric Turin.
