There are various explanations as to the origin of the word Sonora. Here, we will tell you some of the most widely accepted versions. One of these says that when the Spaniards arrived in the lands occupied by the Opata people, they built a chapel and painted an image of the Virgin on a buffalo skin. Over time, when the Opatas began to worship the Virgin, they used to call her Senora instead of the Spanish word Señora (Our Lady). Finally, it would seem that this word became Sonora as we know it today.
