The name certainly has Roman origins; for some historians it derives from the Latin word "casellae" (small houses), while for another school of thought, it derives from "casellum" (tax tool) as there was one located in the area. It is a town near Turin, not far from the regional capital, on the left side of the river Stura di Lanzo. The municipality, which includes the district of Mappano, has boundaries between Venaria Reale and Settimo Torinese. It is known worldwide as the seat of the International Airport of Turin, entitled to one most esteemed and loved Presidents of the Republic of Italy, Sandro Pertini.
Founded by the Romans, nearby its centre passed the ancient road that led to the Valleys of Lanzo. Caselle was a tax toll for all the merchants that sheltered in the centre and even for those that passed through the area. During the Middle Ages, an epidemic plague had a heavy impact on the lives and the whole history of the town. According to the traditions in that dramatic period only four families survived. The fate and the history of the town were strongly related to the those of the Marquis of Monferrato and the Dukes of Savoy.
