Piazza di Porta Ravegnana
Strategically placed at the city entry point of the ancient Via Aemilia, the two towers are the symbol image of the "towered" Bologna , so named for the hundreds of towers and house-towers built in the Middle Ages, of which currently remain little more than twenty. Made in masonry work, they had very important military functions (signalling and defence), besides representing with their imposing heights the social prestige of noble families.
The Asinell tower (XIth century) is the tallest in the city (98 m.). From the top of the tower, which can be reached climbing 498 stairs, a marvelous view of the city can be enjoyed. Next to the Asinelli tower, there is the Garisenda tower (XIth century), which is 48 meters high and is leaning due to a land subsidence happened in the XIIth century. At its base, a tablet reports some verses of the canto XXXI of Dante Alighieri’s Inferno in which the tower is compared to the mythical giant Antaeus.
In front of the towers, there is a statue of Saint Petronio, the patron saint of the city, commissioned to the sculptor Gabriele Brunelli (XVIIth century) by the Company of the Drapers, who had their headquarters here.
Curiosity: among the traditions linked to the Asinelli tower, the following ones should be remembered: one concerns the true measure of the Bolognese tagliatella, which, according to tradition, must be 6,5-7 mm wide and this corresponds to the 12.270th part of the height of the tower; the second recalls that university students should not climb the tower before their graduation because they risk not not to finish their studies.
