 The archeological findings of "Los Infiernos" site prove the importance of Liétor as a border settlement during the Christian Reconquest.These items reflect a period of Muslim occupation in which the population was part of the border with the Christian kingdoms.The Arab knight whose objects were found in Los Infiernos, was probably spending long seasons warring and defending the territories of al-Andalus or trying to annex new ones.After the Reconquest, at the beginning of the 13th century, the monarch Fernando III donated the town to the Order of Santiago, an administrative unit that would last until the mid-nineteenth century.
