The village was named after Canus Natus, a fifth century Roman Catholic Saint, who was a Roman clergyman born with white hair, a quirk synonymous with great wisdom at the time.[3] He was buried in Saint-Cannat, although there was no such place at the time, but soon enough several houses were built into a hamlet.[3]
In the twelfth century, Archbishop Pierre mentioned, 'Castrum Santi - Cannati' in a paper.[3]
In the thirteenth century, villagers turned on their archbishop and pledged allegiance to the Lord of the Baux-de-Provence, and then to the Kings of Sicily (namely, Frederic III of Aragon, or perhaps Louis XIII).[3] This, however, only lasted three years.[3] In the same century, the Knights Templar established a settlement there.[3]
On 11 June 1909 a terrible earthquake destroyed almost everything.[3] Shortly after, the houses were re-built in the same architectural style.[3] Both in 1984 and 1994 huge floods ravaged most houses.[3]
It has retained several fountains dating back to the 17th and 18th century, the remains of the medieval ramparts and the chateau, which today houses the town hall and museum.[3] The Route nationale 7 bisects the village.
There is a polo club, Polo Club de Saint Cannat, opened in the 1970s.[4] It organizes the Open d'Aix and the Tournoi de Noel every year.[5]
There is also an entertainment park called Village des automates.[6]
