It’s a majestic sculpture composed of two elements, leaning and parallels, colored of white and black, in a delicate harmony of empty and solid. The sculpture, high 18m. has been realized in cement (reinforced concrete) in chromatic contrasting. More than the others, this sculpture testifies the relationship man-environment through the rationality of its conception and the lightness with which the cement becomes bi-dimensional and practicable. The sculpture invites the visitor to pass through it, like cross a door that take in an other time, in the archaic past. Then, we realize of the immensity of the sky, under which the history slides since a remote time. A refuge or a barrier placed between the imaginary reality.
