 Its origin dates from the 11th century, when it was founded by shepherds from Tierra de Cameros and Calahorra after its reconquest by García Sánchez III of Navarre in 1045.It was part of the town of Calahorra until it became independent in 1664, under the reign of Philip IV by means of a considerable sum of money lent by the friars of Fitero, whose monastery maintained bonds.After many lawsuits what was from then called Arnedo de Ebro passed into the hands of Manuel Íñiguez de Arnedo.
