In the process of becoming Biosphere Certified, León, a crossroads, owes its outstanding heritage to the succession of peoples that lived in these lands: Astures (a Celtic tribe), Romans, Sueves, Visigoths, Arabs, Christian kingdoms… They all contributed to the creation of a history whose traces are visible in the character of current Leonese people, as well as in the monuments that enhance the province.
