This is a detail of the Railway Bridge Garbatella, the one entitled to Settimia Spizzichino.
Bridge, however, posted in full later.
In this photo I wanted to emphasize geometric forms, exalting them with a strong contrast highlighting , the basic shape of the structure: the triangle.
I do not know if it was on purpose or wanted was random.
Of course it would be easy and perhaps imaginative approach the geometric shape based on the triangle with the beloved symbol in Freemasonry, the Builders of antiquity par excellence.
To you will judge.
Anyway thanks for your Like.
