Charming stretch of street which currently houses the homonymous bar, it derives its name from the presence of some florists’. In the back of one of these, in November 1794, two university students - Luigi Zamboni (from Bologna) and Giovanni Battista De Rolandis (from Asti) – prepared an attempted insurrection against the papal government, soon failed.
The present construction, named Casa Stagni, was renovated by the end of XIXth century by  Augusto Sezanne for the homonymous owner who purchased the building, formerly belonged to the Scappi family, which still incorporates the XIIIth century tower. According to the legend, the Scappi family was awarded the noble title and so called because they had failed the attempted escape of King Enzo (in Italian, Scappi means escape). It is said that a woman of the family, seeing King Enzo hidden in a basket, shouted "run run" making him be recaptured by the Bolognese.
The Scappi Tower is 39 meters high and at its base there is la Coroncina, one of the oldest shops in Bologna (1694), which originally sold religious items.
