This enigmatic construction consists of a tower like structure penetrating 27 metre deep in the ground. Depending on the direction you choose, in is said to symbolise either a journey down into the depths of the earth, or a climb out of the darkness into the light, the journey through the earth is like a rebirth through mother natures womb, from where all things come and where one day all shall return. The fact is that nobody is really sure of the reason leading its construction nor its use. Its spiral staircase is said to evoke Dante's Divine Comedy and the path through the different circle of Hell, while other symbolism related with freemasonry can be appreciated in many details.
