A small amount of explosives were also placed under a nearby bridge that bridged the Ginestra river.
From May 1893, during the period of the Fasci Siciliani, the peasants of the neighbouring towns of Piana degli Albanesi, San Giuseppe Jato and San Cipirello used to gather at Portella della Ginestra for the Labour Day celebrations at the initiative of the physician and peasant leader Nicola Barbato, who used to speak to the crowd from a big rock that was later called "Barbato's Stone".
