Under the tower of Frederick II of Swabia, in Enna, Sicily, there is an underground passage that no one knows where it leads or where it ends.
Some people from my hometown of Enna claim that the underground passage was used to connect the tower to the Castle of Lombardy, which was also built by Frederick II and is at least a kilometer away. However, there is no evidence of this. It might just be town talk.
The fact is that nobody ever dared to walk through the underground passage. Where could it lead?
The answer is just one: the Tower of Frederic II of Swabia in Enna is shrouded in mystery, like Castel Del Monte in Puglia. Both were built by Frederick II of Swabia on an octagonal plan and had no military function. It is said that Castel Del Monte is a huge safe to enclose a legendary object: the Holy Grail. Could the underground passage under the Tower of Frederick II of Swabia in Enna also hide something?
