This stream is called Arraiaga downstream of the Egurrola bridge. Adjacent municipalities Alkiza limits to the north with Larraul and Asteasu; to the south with Hernialde, Tolosa, Albiztur and Bidania-Goiatz; to the east with Anoeta; and to the west with Errezil. History The first human footprints in Alkiza date back to the Bronze Age. Ceramic pieces in the Olatzazpi cave and the burial mound of the place called Itzuregi are an example of this. The first written references to Alkiza are from 1348. In fact, by order of the King of Castile Alfonso XI, the list of noblemen of Tolosa was drawn up. In this list there are several Alkiza households. Alkiza is mentioned administratively associated to Tolosa. In 1396 Tolosa recognized Alkiza the right to choose its judges.
