Other unique features of its kind: the three external spiral staircases and the Marathon Tower, an exquisitely political-propaganda work, with the essential and rational momentum of its 55 meters vertically.
But in the history of this structure there are not only football or athletics matches. A much more singular episode is remembered by many among the audience on 27th October 1954.
On the field there were two teams, Fiorentina and Pistoiese, with very different stories and goals.
Well, during the game, exactly at 2:20 pm, a strange fact happened: all the spectators present, about ten thousand, raise a roar but not for some action on the pitch. The eyes of tens of thousands of fans, in fact, were no longer fixed on the important game that was about to stop before their eyes, but were turned towards the sky where they could see some strange objects in the shape of an egg or, depending on the testimonies reported, of Cuban cigar.
The same players, after a first moment in which they had to understand what it was, literally stopped playing because they were strongly affected by what was happening over their heads. In short: the Artemio Franchi Stadium witnessed a real UFO sighting.
