On Monte Jato, inside the boundaries of the Ancient city of Jetas (which was benefiting from a incredible strategic status due to the "invisibility" from below of its buildings), the last Arab stronghold of Sicily found shelter.
Here, during the long battles and sieges which lasted from 1222 to 1246 and committed by Frederick II and his troops, the last Muslims were defeated and deported to Lucera in Apulia.
These historical events are closely connected with the lands of the Farm.
In fact, while the Swabian troops were stopping by Piano Campo (which takes the name from the fact that it was the area where the camp of Frederick’s army was placed), the Emperor was following the Arab movements and was leading the operations from the so-called "Campanaro", the picturesque round rock on the summit of Argivocale (a name which comes from Arab, meaning "pierced rock").
It is told that the last battle of the Swabian troops was won with a very clever stratagem: during the night a flock of goats, to whose horns the Swabian soldiers had hanged some torches, was pushed from below towards the western side of Monte Jato.
The Arabs, noticing such a great movement of lights and torches, were convinced it would be the final attack and moved all troops over the western city walls to push back the assault.
At the same time, the main army of the Emperor had outflanked the mount and, thanks to the help of some explorers, they had found the bristling and steep path of the "Scal'o ferro" (Iron Stair) that gave access to the mount from the eastern side.
This way, they could climb the slope unnoticed and surprise the Arab from behind, killing them with their swords and razing the city to the ground.
