Sfax Olive Oil Festival in Sfax
The closest verified real event is the Festival International de l'Olivier a Sfax (Sfax Olive Tree/Oil Festival), documented from at least 2015 onward, with a 2nd edition held January 26-30, 2018, and a 4th edition around March 2022, centered on Sfax's Institut de l'Olivier and hosted alongside a best monovarietal olive oil competition.
A full 260-400 word evergreen story is not written for this entry because the festival's founding date and consistency across years remain unclear, and inventing a longer history would overstate certainty.
