Leonor, the 12-year-old future Queen of Spain is set to undertake her first official visit to her principality, Asturias, in September. The young Princess of Asturias will travel with her parents Queen Letizia and King Felipe, as well as her younger sister Infanta Sofía to the northwest region of Spain. The visit will reportedly coincide with the Day of Asturias (September 8), during which the royal family will participate in commemorative events.
"Prince or Princess of Asturias" is the substantive title used by the heir apparent to the Spanish throne.
