The incoming origins from the legend and the myth, without letting even the name free ("Place of red stones") of this "fable". This legend has many different versions reaffirmed by some and refuted by others.

The central core of this tale says that by the year 870 or 888 of our age, in that place named Padura (where Arrigorriaga would be located), the armies of the Lord of Biscay, the first according to the history, defeated in a bloody battle the people from León, led by the prince Ordoño, successor to the crown of León and son of the king Alfonso "El Magno". Arrigorriaga would have its origins in the spilt blood that covered the fighting ground.
